You can: + + * Develop new internal test cases + * Integrate the tests from your feature project + * Develop the framework to ease the integration of external test cases + * Develop the API / Test collection framework + * Develop dashboards or automatic reporting portals + +This document describes how, as a developer, you may interact with the +Functest project. The first section details the main working areas of +the project. The Second part is a list of "How to" to help you to join +the Functest family whatever your field of interest is. + + +======================== +Functest developer areas +======================== + + +Functest High level architecture +================================ + +Functest is project delivering a test container dedicated to OPNFV. +It includes the tools, the scripts and the test scenarios. + +Functest can be described as follow:: + + +----------------------+ + | | + | +--------------+ | +-------------------+ + | | | | Public | | + | | Tools | +------------------+ OPNFV | + | | Scripts | | | System Under Test | + | | Scenarios | +------------------+ | + | | | | Management | | + | +--------------+ | +-------------------+ + | | + | Functest Docker | + | | + +----------------------+ + +Functest internal test cases +============================ +The internal test cases in Danube are: + + * healthcheck + * connection_check + * api_check + * vping_ssh + * vping_userdata + * odl + * snaps_smoke + * tempest_smoke_serial + * rally_sanity + * tempest_full_parallel + * rally_full + * cloudify_ims + +By internal, we mean that this particular test cases have been +developped and/or integrated by functest contributors and the associated +code is hosted in the Functest repository. +An internal case can be fully developped or a simple integration of +upstream suites (e.g. Tempest/Rally developped in OpenStack are just +integrated in Functest). +The structure of this repository is detailed in `[1]`_. +The main internal test cases are in the opnfv_tests subfolder of the +repository, the internal test cases are: + + * sdn: odl, onos + * openstack: healthcheck, vping_ssh, vping_userdata, tempest_*, rally_*, connection_check, api_check, snaps_smoke + * vnf: cloudify_ims + +If you want to create a new test case you will have to create a new +folder under the testcases directory. + +Functest external test cases +============================ +The external test cases are inherited from other OPNFV projects, +especially the feature projects. + +The external test cases are: + + * promise + * doctor + * onos + * bgpvpn + * copper + * security_scan + * sfc-odl + * sfc-onos + * parser + * domino + * multisite + * opera_ims + * orchestra_ims + + +The code to run these test cases may be directly in the repository of +the project. We have also a **features** sub directory under opnfv_tests +directory that may be used (it can be usefull if you want to reuse +Functest library). + +Functest framework +================== + +Functest can be considered as a framework. +Functest is release as a docker file, including tools, scripts and a CLI +to prepare the environement and run tests. +It simplifies the integration of external test suites in CI pipeline +and provide commodity tools to collect and display results. + +Since Colorado, test categories also known as tiers have been created to +group similar tests, provide consistant sub-lists and at the end optimize +test duration for CI (see How To section). + +The definition of the tiers has been agreed by the testing working group. + +The tiers are: + * healthcheck + * smoke + * features + * components + * performance + * vnf + * stress + +Functest abstraction classes +============================ + +In order to harmonize test integration, 3 abstraction classes have been +introduced in Danube: + + * testcase_base: base for any test case + * feature_base: abstraction for feature project + * vnf_base: abstraction for vnf onboarding + +The goal is to unify the way to run test from Functest. + +feature_base and vnf_base inherit from testcase_base. + + +-----------------------------------------+ + | | + | Testcase_base | + | | + | - init() | + | - run() | + | - publish_report() | + | - check_criteria() | + | | + +-----------------------------------------+ + | | + V V + +--------------------+ +--------------------------+ + | | | | + | feature_base | | vnf_base | + | | | | + | - prepare() | | - prepare() | + | - post() | | - deploy_orchestrator() | + | - parse_results() | | - deploy_vnf() | + | | | - test_vnf() | + | | | - clean() | + | | | - execute() | + | | | | + +--------------------+ +--------------------------+ + + +Functest util classes +===================== + +In order to simplify the creation of test cases, Functest develops some +functions that can be used by any feature or internal test cases. +Several features are supported such as logger, configuration management and +Openstack capabilities (snapshot, clean, tacker,..). +These functions can be found under <repo>/functest/utils and can be described as +follows: + +functest/utils/ +|-- config.py +|-- constants.py +|-- env.py +|-- functest_constants.py +|-- functest_logger.py +|-- functest_utils.py +|-- openstack_clean.py +|-- openstack_snapshot.py +|-- openstack_tacker.py +`-- openstack_utils.py + +Note that for Openstack, keystone v3 is now deployed by default by compass, +fuel and joid in Danube. All installers still support keysone v2 (deprecated in +next version). + +Test collection framework +========================= + +The OPNFV testing group created a test collection database to collect +the test results from CI: + + + http://testresults.opnfv.org/test/swagger/spec.html + + Authentication: opnfv/api@opnfv + +Any test project running on any lab integrated in CI can push the +results to this database. +This database can be used to see the evolution of the tests and compare +the results versus the installers, the scenarios or the labs. + + +Overall Architecture +-------------------- +The Test result management can be summarized as follows:: + + +-------------+ +-------------+ +-------------+ + | | | | | | + | Test | | Test | | Test | + | Project #1 | | Project #2 | | Project #N | + | | | | | | + +-------------+ +-------------+ +-------------+ + | | | + V V V + +-----------------------------------------+ + | | + | Test Rest API front end | + | http://testresults.opnfv.org/test | + | | + +-----------------------------------------+ + A | + | V + | +-------------------------+ + | | | + | | Test Results DB | + | | Mongo DB | + | | | + | +-------------------------+ + | + | + +----------------------+ + | | + | test Dashboard | + | | + +----------------------+ + +TestAPI description +------------------- +The TestAPI is used to declare pods, projects, test cases and test +results. Pods are the pods used to run the tests. +The results pushed in the database are related to pods, projects and +cases. If you try to push results of test done on non referenced pod, +the API will return an error message. + +An additional method dashboard has been added to post-process +the raw results in release Brahmaputra (deprecated in Colorado). + +The data model is very basic, 4 objects are created: + + * Pods + * Projects + * Testcases + * Results + +Pods:: + + { + "id": <ID>, + "details": <URL description of the POD>, + "creation_date": "YYYY-MM-DD HH:MM:SS", + "name": <The POD Name>, + "mode": <metal or virtual>, + "role": <ci-pod or community-pod or single-node> + }, + +Projects:: + + { + "id": <ID>, + "name": <Name of the Project>, + "creation_date": "YYYY-MM-DD HH:MM:SS", + "description": <Short description> + }, + +Testcases:: + + { + "id": <ID>, + "name":<Name of the test case>, + "project_name":<Name of belonged project>, + "creation_date": "YYYY-MM-DD HH:MM:SS", + "description": <short description>, + "url":<URL for longer description> + }, + +Results:: + + { + "_id": <ID>, + "case_name": <Reference to the test case>, + "project_name": <Reference to project>, + "pod_name": <Reference to POD where the test was executed>, + "installer": <Installer Apex or Compass or Fuel or Joid>, + "version": <master or Colorado or Brahmaputra>, + "start_date": "YYYY-MM-DD HH:MM:SS", + "stop_date": "YYYY-MM-DD HH:MM:SS", + "build_tag": <such as "jenkins-functest-fuel-baremetal-daily-master-108">, + "scenario": <Scenario on which the test was executed>, + "criteria": <PASS or FAILED>, + "trust_indicator": { + "current": 0, + "histories": [] + } + } + +The API can described as follows.

The token value is added as a masked password. + +.. code-block:: python + + headers['X-Auth-Token'] = os.environ.get('TestApiToken') + +The above example is in Python. Token based authentication has been added so that only ci pods +jenkins job can have access to the database. + +Please note that currently token authorization is implemented but is not yet enabled. + + Automatic reporting + =================== + + An automatic reporting page has been created in order to provide a + consistant view of the scenarios. + In this page, each scenario is evaluated according to test criteria. + The code for the automatic reporting is available at `[8]`_. + + The results are collected from the centralized database every day and, + per scenario. A score is calculated based on the results from the last + 10 days. This score is the addition of single test scores. Each test + case has a success criteria reflected in the criteria field from the + results. + + Considering an instance of a scenario os-odl_l2-nofeature-ha, the + scoring is the addition of the scores of all the runnable tests from the + categories (tiers healthcheck, smoke and features) + corresponding to this scenario. + + + +---------------------+---------+---------+---------+---------+ + | Test | Apex | Compass | Fuel | Joid | + +=====================+=========+=========+=========+=========+ + | vPing_ssh | X | X | X | X | + +---------------------+---------+---------+---------+---------+ + | vPing_userdata | X | X | X | X | + +---------------------+---------+---------+---------+---------+ + | tempest_smoke_serial| X | X | X | X | + +---------------------+---------+---------+---------+---------+ + | rally_sanity | X | X | X | X | + +---------------------+---------+---------+---------+---------+ + | odl | X | X | X | X | + +---------------------+---------+---------+---------+---------+ + | promise | | | X | X | + +---------------------+---------+---------+---------+---------+ + | doctor | X | | X | | + +---------------------+---------+---------+---------+---------+ + | security_scan | X | | | | + +---------------------+---------+---------+---------+---------+ + | parser | | | X | | + +---------------------+---------+---------+---------+---------+ + | copper | X | | | X | + +---------------------+---------+---------+---------+---------+ + + All the testcases listed in the table are runnable on + os-odl_l2-nofeature scenarios. + If no result is available or if all the results are failed, the test + case get 0 point. + If it was succesfull at least once but not anymore during the 4 runs, + the case get 1 point (it worked once). + If at least 3 of the last 4 runs were successful, the case get 2 points. + If the last 4 runs of the test are successful, the test get 3 points. + + In the example above, the target score for fuel/os-odl_l2-nofeature-ha + is 3x6 = 18 points. + + The scenario is validated per installer when we got 3 points for all + individual test cases (e.g 18/18). + Please note that complex or long duration tests are not considered for + the scoring. The success criteria are not always easy to define and may + require specific hardware configuration. These results however provide + a good level of trust on the scenario. + + A web page is automatically generated every day to display the status. + This page can be found at `[9]`_. For the status, click on Status menu, + you may also get feedback for vims and tempest_smoke_serial test cases. + + Any validated scenario is stored in a local file on the web server. In + fact as we are using a sliding windows to get results, it may happen + that a successful scenarios is no more run (because considered as + stable) and then the number of iterations (4 needed) would not be + sufficient to get the green status. + + Please note that other test cases (e.g. sfc_odl, bgpvpn) need also + ODL configuration addons and as a consequence specific scenario. + There are not considered as runnable on the generic odl_l2 scenario. + +Dashboard +========= + +Dashboard is used to provide a consistant view of the results collected +in CI. +The results showed on the dashboard are post processed from the Database, +which only contains raw results. + +In Brahmaputra, we created a basic dashboard. +Since Colorado, it was decided to adopt ELK framework. Mongo DB results +are extracted to feed Elasticsearch database (`[7]`_). + +A script was developed to build elasticsearch data set. This +script can be found in `[16]`_. + +For next versions, it was decided to integrated bitergia dashboard. +Bitergia already provides a dashboard for code and infrastructure. +A new Test tab will be added. The dataset will be built by consuming +the TestAPI. + + +======= +How TOs +======= + +How Functest works? +=================== + +The installation and configuration of the Functest docker image is +described in `[1]`_. + +The procedure to start tests is described in `[2]`_ + + +How can I contribute to Functest? +================================= + +If you are already a contributor of any OPNFV project, you can +contribute to functest. If you are totally new to OPNFV, you must first +create your Linux Foundation account, then contact us in order to +declare you in the repository database. + +We distinguish 2 levels of contributors: + + * the standard contributor can push patch and vote +1/0/-1 on any Functest patch + * The commitor can vote -2/-1/0/+1/+2 and merge + +Functest commitors are promoted by the Functest contributors. + + +Where can I find some help to start? +==================================== + +This guide is made for you. You can also have a look at the project wiki +page `[10]`_. +There are references on documentation, video tutorials, tips... + +You can also directly contact us by mail with [Functest] prefix in the +title at opnfv-tech-discuss@lists.opnfv.org or on the IRC chan +#opnfv-functest. + + +What kind of testing do you do in Functest? +=========================================== + +Functest is focusing on Functional testing. The results must be PASS or +FAIL. We do not deal with performance and/or qualification tests. +We consider OPNFV as a black box and execute our tests from the jumphost +according to Pharos reference technical architecture. + +Upstream test suites are integrated (Rally/Tempest/ODL/ONOS,...). +If needed Functest may bootstrap temporarily testing activities if they +are identified but not covered yet by an existing testing project (e.g +security_scan before the creation of the security repository) + + +How test constraints are defined? +================================= + +Test constraints are defined according to 2 paramaters: + + * The scenario (DEPLOY_SCENARIO env variable) + * The installer (INSTALLER_TYPE env variable) + +A scenario is a formal description of the system under test. +The rules to define a scenario are described in `[4]`_ + +These 2 constraints are considered to determinate if the test is runnable +or not (e.g. no need to run onos suite on odl scenario). + +In the test declaration for CI, the test owner shall indicate these 2 +constraints. The file testcases.yaml `[5]`_ must be patched in git to +include new test cases. A more elaborated system based on template is +planned for next releases + +For each dependency, it is possible to define a regex:: + + name: promise + criteria: 'success_rate == 100%' + description: >- + Test suite from Promise project. + dependencies: + installer: '(fuel)|(joid)' + scenario: '' + +In the example above, it means that promise test will be runnable only +with joid or fuel installers on any scenario. + +The vims criteria means any installer and exclude onos and odl with +bgpvpn scenarios:: + + name: vims + criteria: 'status == "PASS"' + description: >- + This test case deploys an OpenSource vIMS solution from Clearwater + using the Cloudify orchestrator. It also runs some signaling traffic. + dependencies: + installer: '' + scenario: '(ocl)|(nosdn)|^(os-odl)((?!bgpvpn).)*$' + + +How to write and check constaint regex? +======================================= + +Regex are standard regex. You can have a look at `[11]`_ + +You can also easily test your regex via an online regex checker such as `[12]`_. +Put your scenario in the TEST STRING window (e.g. os-odl_l3-ovs-ha), put +your regex in the REGULAR EXPRESSION window, then you can test your rule +. + + +How to know which test I can run? +================================= + +You can use the API `[13]`_.

The project prosposal page is here `[1]`_. +The intern project was assigned to Svk Rohit and was mentored by S. Feng, J.Lausuch, M.Richomme. +The link to the patches submitted is `[2]`_. The internship was successfully completed and the +documentation is as follows. + +Problem Statement: +------------------ + +The problem statement could be divided into pending features that needed to be added into TestAPI +repo. The following were to be accomplished within the internship time frame. + +* **Add verification jenkins job for the TestAPI code** + The purpose of this job is to verify whehter the unit tests are successful or not with the + inclusion of the patchset submitted. + +* **Automatic update of opnfv/testapi docker image** + The docker image of TestAPI is hosted in the opnfv docker hub. To ensure that the TestAPI image + is always updated with the repository, automatic updation of the image is necessary and a job + is triggered whenever a new patch gets merged. + +* **Automation deployment of testresults.opnfv.org/test/ website** + In the same manner as the docker image of TestAPI is updated, the TestAPI website needs to be + in sync with the repository code. So, a job has been added to the opnfv jenkins ci for the + updation of the testresults website. + +* **Generate static documentation of TestAPI calls** + The purpose of this is to give an static/offline view of TestAPI. If someone wants to have a + look at the Restful APIs of TestAPI, he/she does't need to go to the website, he can download + a html page and view it anytime. + +* **Backup MongoDB of TestAPI** + The mongoDB needs to be backed up every week. Till now it was done manually, but due to this + internship, it is now automated using a jenkins job. + +* **Add token based authorization to the TestAPI calls** + The token based authorization was implemented to ensure that only ci_pods could access the + database. Authentication has been added to only delete/put/post requests. + +Curation Phase: +--------------- + +The curation phase was the first 3 to 4 weeks of the internship. This phase was to get familiar +with the TestAPI code and functionality and propose the solutions/tools for the tasks mentioned +above. Swagger codegen was choosen out of the four tools proposed `[3]`_ for generating static +documentaion. + +Also, specific amount of time was spent on the script flow of the jenkins jobs. The automatic +deployment task involves accessing a remote server from inside the jenkins build. The deployment +had to be done only after the docker image update is done. For these constraints to satisfy, a +multijob jenkins job was choosen instead of a freestyle job. + +Important Links: +---------------- + +* MongoDB Backup Link - `[4]`_ +* Static Documentation - `[5]`_ +* TestAPI Token addition to ci_pods - `[6]`_ + +Schedule: +========= + +The progress and completion of the tasks is described in the below table. + ++--------------------------+------------------------------------------+ +| **Date** | **Comment** | +| | | ++--------------------------+------------------------------------------+ +| Nov 14th - Dec 31st | Understand TestAPI code and the | +| | requirements. | ++--------------------------+------------------------------------------+ +| Jan 1st - Jan 7th | Add jenkins job to create static | +| | documentation and write build scripts. | ++--------------------------+------------------------------------------+ +| Jan 8th - Jan 21st | Add verification jenkins job for unit | +| | tests. | ++--------------------------+------------------------------------------+ +| Jan 22nd - Jan 28th | Add jenkins job for mongodb backup | +| | | ++--------------------------+------------------------------------------+ +| Jan 29th - Feb 11th | Enable automatic deployment of | +| | testresults.opnfv.org/test/ | ++--------------------------+------------------------------------------+ +| Feb 12th - Feb 17th | Add token based authentication | +| | | ++--------------------------+------------------------------------------+ + +FAQ's +===== + +This section lists the problems that I have faced and the understanding that I have acquired during +the internship. This section may help other developers in solving any errors casused because of the +code written as a part of this internship. + + +TestAPI +------- + +What is the difference between defining data_file as "/etc/.." and "etc/.." in setup.cfg ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If in the setup.cfg, it is defined as + +[files] +data_files = +etc/a.conf = etc/a.conf.sample + +then it ends up installed in the /usr/etc/. With this configuration, it would be installed +correctly within a venv. but when it is defined as + +[files] +data_files = +/etc/a.conf = etc/a.conf.sample + +then it ends up installed on the root of the filesystem instead of properly be installed within the +venv. + +Which attribute does swagger-codegen uses as the title in the generation of document generation ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +It uses the nickname of the api call in swagger as the title in the generation of the document +generation. + +Does swagger-codegen take more than one yaml file as input ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +No, swagger-codegen only takes one yaml file as input to its jar file. If there more than one yaml +file, one needs to merge them and give it as an input keeping mind the swagger specs. + + +Jenkins & JJB +------------- + +Which scm macro is used for verification jenkins jobs ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are two macros for scm one is git-scm and other git-scm-gerrit. git-scm-gerrit is used for +verification jenkins job. + +Does the virtualenv created in one build script exists in other build scripts too ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +No, the virtualenv created in one build script only exists in that build script/shell. + +What parameters are needed for the scm macros ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Project and Branch are the two parameters needed for scm macros. + +What is the directory inside the jenkins build ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The directory of the jenkins build is the directory of the repo. `ls $WORKSPACE` command will give +you all the contents of the directory. + +How to include a bash script in jenkins job yaml file ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +An example might be apt here as an answer. + +builders: + - shell: + !include-raw: include-raw001-hello-world.sh + + +How do you make a build server run on a specific machine ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +It can be done by defining a label parameter 'SLAVE_LABEL' or in OPNFV , there are macros for each +server, one can use those parameter macros. +Ex: opnfv-build-defaults. Note, if we use macro, then no need to define GIT_BASE, but if one uses +SLAVE_LABEL, one needs to define a parameter GIT_BASE. This is because macro already has GIT_BASE +defined. + +What job style should be used when there is a situation like one build should trigger other builds +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +or when different build scripts need to be run on different machines ? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +MultiJob style should be used as it has phases where each phase can be taken as a build scipt and +can have its own parameters by which one can define the SLAVE_LABEL parameter. + +References: +=========== + +_`[1]` : https://wiki.opnfv.org/display/DEV/Intern+Project%3A+testapi+evolution + +_`[2]` : https://gerrit.opnfv.org/gerrit/#/q/status:merged+owner:%22Rohit+Sakala+%253Crohitsakala%2540gmail.com%253E%22 + +_`[3]` : https://docs.google.com/document/d/1jWwVZ1ZpKgKcOS_zSz2KzX1nwg4BXxzBxcwkesl7krw/edit?usp=sharing + +_`[4]` : http://artifacts.opnfv.org/testapibackup.html + +_`[5]` : http://artifacts.opnfv.org/releng/docs/testapi.html + +_`[6]` : http://artifacts.opnfv.org/functest/docs/devguide/index.html#test-api-authorization diff --git a/docs/testing/developer/internship/unit_tests/index.rst b/docs/testing/developer/internship/unit_tests/index.rst new file mode 100644 index 00000000..f969aa72 --- /dev/null +++ b/docs/testing/developer/internship/unit_tests/index.rst @@ -0,0 +1,70 @@ +======= +License +======= + +Functest Docs are licensed under a Creative Commons Attribution 4.0 +International License. +You should have received a copy of the license along with this. +If not, see <http://creativecommons.org/licenses/by/4.0/>. + +=================== +Functest Unit tests +=================== + +Author: Ashish Kumar +Mentors: H.Yao, J.Lausuch, M.Richomme + +Abstract +======== + + +Version history +=============== + ++------------+----------+------------------+------------------------+ +| **Date** | **Ver.** | **Author** | **Comment** | +| | | | | ++------------+----------+------------------+------------------------+ +| 2016-??-?? | 0.0.1 | Morgan Richomme | Beginning of the | +| | | (Orange) | Internship | ++------------+----------+------------------+------------------------+ + + +Overview: +========= + + + + +Problem Statement: +------------------ + + + +Curation Phase +-------------- + + + + + +Schedule: +========= + + + ++--------------------------+------------------------------------------+ +| **Date** | **Comment** | +| | | ++--------------------------+------------------------------------------+ +| December - January | ........ | ++--------------------------+------------------------------------------+ +| January - february | ........ | ++--------------------------+------------------------------------------+ + + +References: +=========== + +.. _`[1]` : https://wiki.opnfv.org/display/DEV/Intern+Project%3A+Functest+unit+tests + diff --git a/docs/testing/developer/internship/vnf_catalog/index.rst b/docs/testing/developer/internship/vnf_catalog/index.rst new file mode 100644 index 00000000..df763339 --- /dev/null +++ b/docs/testing/developer/internship/vnf_catalog/index.rst @@ -0,0 +1,170 @@ +======= +License +======= + +Functest Docs are licensed under a Creative Commons Attribution 4.0 +International License. +You should have received a copy of the license along with this. +If not, see <http://creativecommons.org/licenses/by/4.0/>. + +======================= +Open Source VNF Catalog +======================= + +Author: Kumar Rishabh +Mentors: B.Souville, M.Richomme, J.Lausuch + +Abstract +======== + + + +Version hissory +=============== + ++------------+----------+------------------+------------------------+ +| **Date** | **Ver.** | **Author** | **Comment** | +| | | | | ++------------+----------+------------------+------------------------+ +| 2016-12-12 | 0.0.1 | Morgan Richomme | Beginning of the | +| | | (Orange) | Internship | ++------------+----------+------------------+------------------------+ + + +Overview: +========= + + +This project aims to create an Open Source catalog for reference and +classification of Virtual Network Functions (VNFs)s available on +Internet. The classification method proposed will be in sync with the +requirements of Telcos active in NFV landscape. The project aims to have +running web platform similar to [1] by the mid of internship (2nd week +of March). By the penultimate month of internship I aim to have fully +functional implementation of an Open Source VNF in functest. + + +Problem Statement: +------------------ + +OPNFV aims to be the reference platform for development, +standardization and integration of Open Source NFV components across +various Open Source Platforms. It mainly deals with the infrastructure +through the Network Function Virtualization Infrastructure (NFVI) and +Virtual Infrastructure manager (VIM). The MANO (Management and +orchestration) stacks have been introduced recently. VNFs are not +directly in OPNFV scope, however VNFs are needed to test and qualify the +infrastructure. In this regard having a common curated Open Source +Reference VNF catalog would be of immense importance to community. + +Since major focus of OPNFV is Telcos, a curated platform targeted from +industry point of view would be very useful. We plan to divide the +entire project into three major phases(with some iterative improvements +and overlaps) + + +Curation Phase +-------------- +This phase pertains to studying various Open Source VNFs available and +classification of them based on certain parameters. The parameters that +I currently have in mind are: + * Developer Metrics: These pertain to repo characteristics of VNF under + study + * Usage Statistics - Activity, Number of Commits, stars + * Maturity Statistics - For instance if an NFV community decides code + coverage is important for them, it shows the NFV community is serious + about taking the project forward + * Technical Tagging: These are the tags that pertain to technical + characteristics of a VNF + * Broad Use Cases - Whether the VNF fits strictly in IaaS, PaaS or + SaaS layer or is an hybrid of two/all. + * Generic Use Cases - This in my opinion is the broadest + classification category. For instance a VNF could be built with a + broad idea of powering IOT devices at home or from usage perspective + of Telco Operators (vFW, vEPC, vIMS, vCDN, vAAA, vCPE,...).`[2]`_ + * Fields of Application + * Library Status - Whether APIs are standardized, support RESTful + services. + * Dependency Forwarding Graph - This is pretty complex tagging + mechanism. It essentially tries to establish a graph relationship + between the VNFs (elementary VNFs are used in Service Function + Chaining chains such as Firewall, DPI, content enrichment,..). In my + opinion this is useful immensely. This will allow users to go to + platform and ask a question like - “I have this X tech stack to + support, Y and Z are my use cases, which NFVs should I use to support + this. + * Visitor Score - Based on `[1]`_ I plan to evolve a visitor score for + the platform. This will allow users to score an NFV on certain + parameters, may be post comments. + +**I plan to use the above three scores and evolve cumulative score which +will be displayed next to each of the NFV on the platform.** + + * Platform building phase - This will involve erecting a Web Platform + which will be similar to this `[1]`_. I am decently familiar with + Django and hence I will write the platform in Django. There are two + action plans that I have in mind right now. Either I can start writing + the platform simultaneously which will help keep track of my progress + or I can write the platform after 1.5 - 2 months into the internship. + Either way I aim to have the Web Platform ready by March 12. + + * Functest VNF implementation phase - This is the last phase that will + involve writing a fully functional implementation of an Open Source VNF + into Functest. I will undertake this after I am 3 months into the + internship. I have a decent familiarity with python and hence I think + it shouldn’t be too difficult. I need to decide how complex the VNFI + should undertake this exercise for (e.g. AAA such as free radius sounds + relatively easy, vCDN is much more challenging). + This will be decided in consent with my mentors. + + + + +Schedule: +========= +I plan to take this project in 6 months time frame as I want to use it +as a chance to read more about NFVs in particular and SDN in general + + ++--------------------------+------------------------------------------+ +| **Date** | **Comment** | +| | | ++--------------------------+------------------------------------------+ +| December 12 - January 12 | Study the above mentioned metrics | +| | Decide which of them are important for | +| | community (and which are not). | ++--------------------------+------------------------------------------+ +| January 12 - January 27 | Make a database for the above studied | +| | metrics and evolve it further based on | +| | Mentors’ input. + associated API | ++--------------------------+------------------------------------------+ +| January 27 - February 5 | Compile the data collected above and make| +| | it public.

If you need to specifically pull the latest +Functest docker image, then omit the tag argument:: + + docker pull opnfv/functest + +After pulling the Docker image, check that it is available with the +following docker command:: + + [functester@jumphost ~]$ docker images + REPOSITORY TAG IMAGE ID CREATED SIZE + opnfv/functest latest 8cd6683c32ae 2 weeks ago 1.321 GB + opnfv/functest danube.1.0 13fa54a1b238 4 weeks ago 1.29 GB + opnfv/functest colorado.1.0 94b78faa94f7 9 weeks ago 968 MB + +The Functest docker container environment can -in principle- be also +used with non-OPNFV official installers (e.g. 'devstack'), with the +**disclaimer** that support for such environments is outside of the +scope and responsibility of the OPNFV project. + +Accessing the Openstack credentials +----------------------------------- +OpenStack credentials are mandatory and can be retrieved in different +ways. From inside the running Functest docker container the +"functest env prepare" command will automatically look for the +Openstack credentials file "/home/opnfv/functest/conf/openstack.creds" +and retrieve it unless the file already exists. This Functest +environment preparation step is described later in this document. + +WARNING: When the installer type is "joid" you have to have the +credentials file inside the running container **before** initiating the +functest environment preparation. For that reason you have to choose +either one of the options below, since the automated copying does not +work for "joid". + +You can also specifically pass in the needed file prior to running the +environment preparation either: + + * by using the -v option when creating the Docker container. This is + referred to in docker documentation as "Bind Mounting". See the + usage of this parameter in the following chapter. + * or creating a local file '/home/opnfv/functest/conf/openstack.creds' + inside the running container with the credentials in it. Consult + your installer guide for further details. This is however not + instructed in this document. + +NOTE: When the installer type is "fuel" and virtualized deployment +is used, there you have to explicitly fetch the credentials file +executing the following sequence + + #. Create a container as described in next chapter but do not + "Bind Mount" the credentials + #. Log in to container and execute the following command. Replace + the IP with installer address after the "-a" parameter:: + + $REPOS_DIR/releng/utils/fetch_os_creds.sh \ + -d /home/opnfv/functest/conf/openstack.creds \ + -i fuel \ + -a 10.20.0.2 \ + -v + ( -d specifies the full path to the Openstack credential file + -i specifies the INSTALLER_TYPE + -a specifies the INSTALLER_IP + -v indicates a virtualized environment and takes no arguments ) + + #. Continue with your testing, initiate functest environment + preparation, run tests etc. + +In proxified environment you may need to change the credentials file. +There are some tips in chapter: `Proxy support`_ + +Functest Docker parameters +-------------------------- +This chapter explains how to run a container for executing functest +test suites. Numbered list below explains some details of the +recommended parameters for invoking docker container + + #. It is a good practice to assign a precise container name through + the **--name** option. + + #. Assign parameter for installer type:: + + -e "INSTALLER_TYPE=<type>" + # Use one of following apex, compass, fuel or joid + + #. Functest needs to know the IP of some installers:: + + -e "INSTALLER_IP=<Specific IP Address>" + + This IP is needed to fetch RC file from deployment, fetch logs, ... + If not provided, there is no way to fetch the RC file. It must be + provided manually as a volume + + #. Credentials for accessing the Openstack. + Most convenient way of passing them to container is by having a + local copy of the credentials file in Jumphost and then using the + **-v** option. In the example we have local file by the name of + "overcloudrc" and we are using that as an argument:: + + -v ~/overcloudrc:/home/opnfv/functest/conf/openstack.creds + + The credentials file needs to exist in the Docker container + under the path: '/home/opnfv/functest/conf/openstack.creds'. + + **WARNING:** If you are using the Joid installer, you must pass the + credentials using the **-v** option: + -v /var/lib/jenkins/admin-openrc:/home/opnfv/functest/conf/openstack.creds. + See the section `Accessing the Openstack credentials`_ above. + + #. Passing deployment scenario + When running Functest against any of the supported OPNFV scenarios, + it is recommended to include also the environment variable + **DEPLOY_SCENARIO**. The **DEPLOY_SCENARIO** environment variable + is passed with the format:: + + -e "DEPLOY_SCENARIO=os-<controller>-<nfv_feature>-<ha_mode>" + where: + os = OpenStack (No other VIM choices currently available) + controller is one of ( nosdn | odl_l2 | odl_l3 | onos | ocl) + nfv_feature is one or more of ( ovs | kvm | sfc | bgpvpn | nofeature ) + If several features are pertinent then use the underscore + character '_' to separate each feature (e.g. ovs_kvm) + 'nofeature' indicates no NFV feature is deployed + ha_mode (high availability) is one of ( ha | noha ) + + **NOTE:** Not all possible combinations of "DEPLOY_SCENARIO" are + supported. The name passed in to the Functest Docker container + must match the scenario used when the actual OPNFV platform was + deployed. See release note to see the list of supported scenarios. + + **NOTE:** The scenario name is mainly used to automatically detect + if a test suite is runnable or not (e.g. it will prevent ONOS test suite + to be run on ODL scenarios). If not set, Functest will try to run the + default test cases that might not include SDN controller or a specific + feature + + **NOTE:** A HA scenario means that 3 OpenStack controller nodes are + deployed. It does not necessarily mean that the whole system is HA. See + installer release notes for details. + + +Putting all above together, when using installer 'fuel' and an invented +INSTALLER_IP of '10.20.0.2', the recommended command to create the +Functest Docker container is as follows:: + + docker run --name "FunctestContainer" -it \ + -e "INSTALLER_IP=10.20.0.2" \ + -e "INSTALLER_TYPE=fuel" \ + -e "DEPLOY_SCENARIO=os-odl_l2-ovs_kvm-ha" \ + -v ~/overcloudrc:/home/opnfv/functest/conf/openstack.creds \ + opnfv/functest /bin/bash + +After the *run* command, a new prompt appears which means that we are inside +the container and ready to move to the next step. + +For tips on how to set up container with installer Apex, see chapter +`Apex Installer Tips`_. + +Finally, three additional environment variables can also be passed in +to the Functest Docker Container, using the -e +"<EnvironmentVariable>=<Value>" mechanism. The first two of these are +only relevant to Jenkins CI invoked testing and **should not be used** +when performing manual test scenarios:: + + -e "NODE_NAME=<Test POD Name>" \ + -e "BUILD_TAG=<Jenkins Build Tag>" \ + -e "CI_DEBUG=<DebugTraceValue>" + where: + <Test POD Name> = Symbolic name of the POD where the tests are run. + Visible in test results files, which are stored + to the database. This option is only used when + tests are activated under Jenkins CI control. + It indicates the POD/hardware where the test has + been run. If not specified, then the POD name is + defined as "Unknown" by default. + DO NOT USE THIS OPTION IN MANUAL TEST SCENARIOS. + <Jenkins Build tag> = Symbolic name of the Jenkins Build Job. + Visible in test results files, which are stored + to the database. This option is only set when + tests are activated under Jenkins CI control. + It enables the correlation of test results, + which + are independently pushed to the results datbase + from different Jenkins jobs. + DO NOT USE THIS OPTION IN MANUAL TEST SCENARIOS. + <DebugTraceValue> = "true" or "false" + Default = "false", if not specified + If "true" is specified, then additional debug trace + text can be sent to the test results file / log files + and also to the standard console output. + +Apex Installer Tips +------------------- +Some specific tips are useful for the Apex Installer case. If not using +Apex Installer; ignore this section. + +In case of Triple-O based installer (like Apex) the docker container +needs to connect to the installer VM, so it is then required that some +known SSH keys are present in docker container. Since the Jumphost root +SSH keys are already known, easiest way is to use those using the +'Bind mount' method. See below for sample parameter:: + + -v /root/.ssh/id_rsa:/root/.ssh/id_rsa + + NOTE: You need the "sudo" when creating the container to access root + users ssh credentials even the docker command itself might not + require that. + +HINT! In case of Triple-O installers you can find value for the +INSTALLER_IP parameter by executing command and note the returned IP +address:: + + inst=$(sudo virsh list | grep -iEo "undercloud|instack") + sudo virsh domifaddr ${inst} + + NOTE: In releases prior to Colorado, the name 'instack' was + used. Currently the name 'undercloud' is used. + +You can copy the credentials file from the "stack" users home directory +in installer VM to Jumphost. Please check the correct IP from the +command above. In the example below we are using invented IP address +"192.168.122.89":: + + scp stack@192.168.122.89:overcloudrc . + +Here is an example of the full docker command invocation for an Apex +installed system, using latest Functest docker container, for +illustration purposes:: + + sudo docker run -it --name "ApexFuncTestODL" \ + -e "INSTALLER_IP=192.168.122.89" \ + -e "INSTALLER_TYPE=apex" \ + -e "DEPLOY_SCENARIO=os-odl_l2-nofeature-ha" \ + -v /root/.ssh/id_rsa:/root/.ssh/id_rsa \ + -v ~/overcloudrc:/home/opnfv/functest/conf/openstack.creds \ + opnfv/functest /bin/bash + +Compass installer local development env usage Tips +-------------------------------------------------- +In the compass-functest local test case check and development environment, +in order to get openstack service inside the functest container, some +parameters should be configured during container creation, which are +hard to guess for freshman.

A custom built **functest** +CLI utility is available to perform the needed environment preparation +action. Once the environment is prepared, the **functest** CLI utility +can be used to run different functional tests. The usage of the +**functest** CLI utility to run tests is described further in the +Functest User Guide `OPNFV_FuncTestUserGuide`_ + +Prior to commencing the Functest environment preparation, we can check +the initial status of the environment. Issue the **functest env status** +command at the prompt:: + + functest env status + Functest environment is not installed. + + Note: When the Functest environment is prepared, the command will + return the status: "Functest environment ready to run tests." + +To prepare the Functest docker container for test case execution, issue +the **functest env prepare** command at the prompt:: + + functest env prepare + +This script will make sure that the requirements to run the tests are +met and will install the needed libraries and tools by all Functest +test cases. It should be run only once every time the Functest docker +container is started from scratch. If you try to run this command, on +an already prepared enviroment, you will be prompted whether you really +want to continue or not:: + + functest env prepare + It seems that the environment has been already prepared. + Do you want to do it again? [y|n] + + (Type 'n' to abort the request, or 'y' to repeat the + environment preparation) + + +To list some basic information about an already prepared Functest +docker container environment, issue the **functest env show** at the +prompt:: + + functest env show + +======================================================+ + | Functest Environment info | + +======================================================+ + | INSTALLER: apex, 192.168.122.89 | + | SCENARIO: os-odl_l2-nofeature-ha | + | POD: localhost | + | GIT BRANCH: master | + | GIT HASH: 5bf1647dec6860464eeb082b2875798f0759aa91 | + | DEBUG FLAG: false | + +------------------------------------------------------+ + | STATUS: ready | + +------------------------------------------------------+ + + Where: + + INSTALLER: Displays the INSTALLER_TYPE value + - here = "apex" + and the INSTALLER_IP value + - here = "192.168.122.89" + SCENARIO: Displays the DEPLOY_SCENARIO value + - here = "os-odl_l2-nofeature-ha" + POD: Displays the value passed in NODE_NAME + - here = "localhost" + GIT BRANCH: Displays the git branch of the OPNFV Functest + project repository included in the Functest + Docker Container. + - here = "master" + (In first official colorado release + would be "colorado.1.0") + GIT HASH: Displays the git hash of the OPNFV Functest + project repository included in the Functest + Docker Container. + - here = "5bf1647dec6860464eeb082b2875798f0759aa91" + DEBUG FLAG: Displays the CI_DEBUG value + - here = "false" + + NOTE: In Jenkins CI runs, an additional item "BUILD TAG" + would also be listed.

In any other case, check that the credentials are sourced:: + + env|grep OS_ + +This command must show a set of environment variables starting with +*OS_*, for example:: + + OS_REGION_NAME=RegionOne + OS_DEFAULT_DOMAIN=default + OS_PROJECT_NAME=admin + OS_PASSWORD=admin + OS_AUTH_STRATEGY=keystone + OS_AUTH_URL=http://172.30.10.3:5000/v2.0 + OS_USERNAME=admin + OS_TENANT_NAME=admin + OS_ENDPOINT_TYPE=internalURL + OS_NO_CACHE=true + +If the OpenStack command still does not show anything or complains +about connectivity issues, it could be due to an incorrect url given to +the OS_AUTH_URL environment variable. Check the deployment settings. + +SSL Support +----------- +If you need to connect to a server that is TLS-enabled (the auth URL +begins with "https") and it uses a certificate from a private CA or a +self-signed certificate, then you will need to specify the path to an +appropriate CA certificate to use, to validate the server certificate +with the environment variable OS_CACERT:: + + echo $OS_CACERT + /etc/ssl/certs/ca.crt + +However, this certificate does not exist in the container by default. +It has to be copied manually from the OpenStack deployment. This can be +done in 2 ways: + + #. Create manually that file and copy the contents from the OpenStack + controller. + #. (Recommended) Add the file using a Docker volume when starting the + container:: + + -v <path_to_your_cert_file>:/etc/ssl/certs/ca.cert + +You might need to export OS_CACERT environment variable inside the +container:: + + export OS_CACERT=/etc/ssl/certs/ca.crt + +Certificate verification can be turned off using OS_INSECURE=true. For +example, Fuel uses self-signed cacerts by default, so an pre step would +be:: + + export OS_INSECURE=true + +Proxy support +------------- +If your Jumphost node is operating behind a http proxy, then there are +2 places where some special actions may be needed to make operations +succeed: + + #. Initial installation of docker engine First, try following the + official Docker documentation for Proxy settings. Some issues were + experienced on CentOS 7 based Jumphost. Some tips are documented + in section: `Docker Installation on CentOS behind http proxy`_ + below. + + #. Execution of the Functest environment preparation inside the + created docker container Functest needs internet access to + download some resources for some test cases. This might not + work properly if the Jumphost is connecting to internet + through a http Proxy. + +If that is the case, make sure the resolv.conf and the needed +http_proxy and https_proxy environment variables, as well as the +'no_proxy' environment variable are set correctly:: + + # Make double sure that the 'no_proxy=...' line in the + # 'openstack.creds' file is commented out first. Otherwise, the + # values set into the 'no_proxy' environment variable below will + # be ovewrwritten, each time the command + # 'source ~/functest/conf/openstack.creds' is issued. + + cd ~/functest/conf/ + sed -i 's/export no_proxy/#export no_proxy/' openstack.creds + source ./openstack.creds + + # Next calculate some IP addresses for which http_proxy + # usage should be excluded: + + publicURL_IP=$(echo $OS_AUTH_URL | grep -Eo "([0-9]+\.){3}[0-9]+") + + adminURL_IP=$(openstack catalog show identity | \ + grep adminURL | grep -Eo "([0-9]+\.){3}[0-9]+") + + export http_proxy="<your http proxy settings>" + export https_proxy="<your https proxy settings>" + export no_proxy="127.0.0.1,localhost,$publicURL_IP,$adminURL_IP" + + # Ensure that "git" uses the http_proxy + # This may be needed if your firewall forbids SSL based git fetch + git config --global http.sslVerify True + git config --global http.proxy <Your http proxy settings> + +Validation check: Before running **'functest env prepare'** CLI command, +make sure you can reach http and https sites from inside the Functest +docker container. + +For example, try to use the **nc** command from inside the functest +docker container:: + + nc -v opnfv.org 80 + Connection to opnfv.org 80 port [tcp/http] succeeded! + + nc -v opnfv.org 443 + Connection to opnfv.org 443 port [tcp/https] succeeded! + +Note: In a Jumphost node based on the CentOS family OS, the **nc** +commands might not work.

This allows running Functest +on any platform on any Operating System. + +The automated mechanisms inside the Functest Docker container will: + + * Retrieve OpenStack credentials + * Prepare the environment according to the SUT + * Perform the appropriate functional tests + * Push the test results into the OPNFV test result database + +This Docker image can be integrated into CI or deployed independently. + +Please note that the Functest Docker container has been designed for +OPNFV, however, it would be possible to adapt it to any VIM + controller +environment, since most of the test cases are integrated from upstream +communities. + +The functional test cases are described in the Functest User Guide `[2]`_ + + +Prerequisites +============= +The OPNFV deployment is out of the scope of this document but it can be +found in http://docs.opnfv.org. +The OPNFV platform is considered as the System Under Test (SUT) in this +document. + +Several prerequisites are needed for Functest: + + #. A Jumphost to run Functest on + #. A Docker daemon shall be installed on the Jumphost + #. A public/external network created on the SUT + #. An admin/management network created on the SUT + #. Connectivity from the Jumphost to the SUT public/external network + #. Connectivity from the Jumphost to the SUT admin/management network + +WARNING: Connectivity from Jumphost is essential and it is of paramount +importance to make sure it is working before even considering to install +and run Functest. Make also sure you understand how your networking is +designed to work. + +NOTE: **Jumphost** refers to any server which meets the previous +requirements. Normally it is the same server from where the OPNFV +deployment has been triggered previously. + +NOTE: If your Jumphost is operating behind a company http proxy and/or +Firewall, please consult first the section `Proxy Support`_, towards +the end of this document. The section details some tips/tricks which +*may* be of help in a proxified environment. + +Docker installation +------------------- +Docker installation and configuration is only needed to be done once +through the life cycle of Jumphost. + +If your Jumphost is based on Ubuntu, RHEL or CentOS linux, please +consult the references below for more detailed instructions. The +commands below are offered as a short reference. + +*Tip:* For running docker containers behind the proxy, you need first +some extra configuration which is described in section +`Docker Installation on CentOS behind http proxy`_. You should follow +that section before installing the docker engine. + +Docker installation needs to be done as root user. You may use other +userid's to create and run the actual containers later if so desired. +Log on to your Jumphost as root user and install the Docker Engine +(e.g. for CentOS family):: + + curl -sSL https://get.docker.com/ | sh + systemctl start docker + + *Tip:* If you are working through proxy, please set the https_proxy + environment variable first before executing the curl command. + +Add your user to docker group to be able to run commands without sudo:: + + sudo usermod -aG docker <your_user> + +A reconnect is needed. There are 2 ways for this: + #. Re-login to your account + #. su - <username> + +References - Installing Docker Engine on different Linux Operating Systems: + * Ubuntu_ + * RHEL_ + * CentOS_ + +.. _Ubuntu: https://docs.docker.com/engine/installation/linux/ubuntulinux/ +.. _RHEL: https://docs.docker.com/engine/installation/linux/rhel/ +.. _CentOS: https://docs.docker.com/engine/installation/linux/centos/ + +Public/External network on SUT +------------------------------ +Some of the tests against the VIM (Virtual Infrastructure Manager) need +connectivity through an existing public/external network in order to +succeed. This is needed, for example, to create floating IPs to access +VM instances through the public/external network (i.e. from the Docker +container). + +By default, the four OPNFV installers provide a fresh installation with +a public/external network created along with a router. Make sure that +the public/external subnet is reachable from the Jumphost. + +*Hint:* For the given OPNFV Installer in use, the IP sub-net address +used for the public/external network is usually a planning item and +should thus be known. Consult the OPNFV Configuration guide `[4]`_, and +ensure you can reach each node in the SUT, from the Jumphost using the +'ping' command using the respective IP address on the public/external +network for each node in the SUT. The details of how to determine the +needed IP addresses for each node in the SUT may vary according to the +used installer and are therefore ommitted here. + +Connectivity to Admin/Management network on SUT +----------------------------------------------- +Some of the Functest tools need to have access to the OpenStack +admin/management network of the controllers `[1]`_. + +For this reason, check the connectivity from the Jumphost to all the +controllers in cluster in the OpenStack admin/management network range. + +Installation and configuration +============================== + +.. include:: ./configguide.rst + +Integration in CI +================= +In CI we use the Docker image and execute the appropriate commands within the +container from Jenkins. + +Docker creation in set-functest-env builder `[3]`_:: + + envs="-e INSTALLER_TYPE=${INSTALLER_TYPE} -e INSTALLER_IP=${INSTALLER_IP} -e NODE_NAME=${NODE_NAME}" + [...] + docker pull opnfv/functest:$DOCKER_TAG >/dev/null + cmd="sudo docker run -id ${envs} ${volumes} ${custom_params} ${TESTCASE_OPTIONS} opnfv/functest:${DOCKER_TAG} /bin/bash" + echo "Functest: Running docker run command: ${cmd}" + ${cmd} >${redirect} + sleep 5 + container_id=$(docker ps | grep "opnfv/functest:${DOCKER_TAG}" | awk '{print $1}' | head -1) + echo "Container ID=${container_id}" + if [ -z ${container_id} ]; then + echo "Cannot find opnfv/functest container ID ${container_id}.

In the OPNFV Danube system release, +a Functest CLI utility is introduced for easier execution of test procedures. + +**IMPORTANT**: It is assumed here that the Functest Docker container is already +properly deployed and that all instructions described in this guide are to be +performed from *inside* the deployed Functest Docker container. + +.. include:: ./introduction.rst + +The different test cases are described in the remaining sections of this document. + +VIM (Virtualized Infrastructure Manager) +---------------------------------------- + +Healthcheck +^^^^^^^^^^^ +In Colorado release a new Tier 'healthcheck' with one testcase 'healthcheck' +was introduced. The healthcheck testcase verifies that some basic IP connectivity +and essential operations of OpenStack functionality over the command line are +working correctly. + +In particular, the following verifications are performed: + + * DHCP agent functionality for IP address allocation + * Openstack Authentication management functionality via the Keystone API + * OpenStack Image management functionality via the Glance API + * OpenStack Block Storage management functionality via the Cinder API + * OpenStack Networking management functionality via the Neutron API + * Openstack Compute management functionality via the NOVA API + +Self-obviously, successful completion of the 'healthcheck' testcase is a +necessary pre-requisite for the execution of all other test Tiers. + + +vPing_ssh +^^^^^^^^^ + +Given the script **ping.sh**:: + + #!/bin/sh + while true; do + ping -c 1 $1 2>&1 >/dev/null + RES=$? + if [ "Z$RES" = "Z0" ] ; then + echo 'vPing OK' + break + else + echo 'vPing KO' + fi + sleep 1 + done + + +The goal of this test is to establish an SSH connection using a floating IP +on the Public/External network and verify that 2 instances can talk over a Private +Tenant network:: + + vPing_ssh test case + +-------------+ +-------------+ + | | | | + | | Boot VM1 with IP1 | | + | +------------------->| | + | Tester | | System | + | | Boot VM2 | Under | + | +------------------->| Test | + | | | | + | | Create floating IP | | + | +------------------->| | + | | | | + | | Assign floating IP | | + | | to VM2 | | + | +------------------->| | + | | | | + | | Establish SSH | | + | | connection to VM2 | | + | | through floating IP| | + | +------------------->| | + | | | | + | | SCP ping.sh to VM2 | | + | +------------------->| | + | | | | + | | VM2 executes | | + | | ping.sh to VM1 | | + | +------------------->| | + | | | | + | | If ping: | | + | | exit OK | | + | | else (timeout): | | + | | exit Failed | | + | | | | + +-------------+ +-------------+ + +This test can be considered as an "Hello World" example. +It is the first basic use case which **must** work on any deployment. + +vPing_userdata +^^^^^^^^^^^^^^ + +This test case is similar to vPing_ssh but without the use of Floating IPs +and the Public/External network to transfer the ping script. +Instead, it uses Nova metadata service to pass it to the instance at booting time. +As vPing_ssh, it checks that 2 instances can talk to +each other on a Private Tenant network:: + + vPing_userdata test case + +-------------+ +-------------+ + | | | | + | | Boot VM1 with IP1 | | + | +------------------->| | + | | | | + | | Boot VM2 with | | + | | ping.sh as userdata| | + | | with IP1 as $1. | | + | +------------------->| | + | Tester | | System | + | | VM2 exeutes ping.sh| Under | + | | (ping IP1) | Test | + | +------------------->| | + | | | | + | | Monitor nova | | + | | console-log VM 2 | | + | | If ping: | | + | | exit OK | | + | | else (timeout) | | + | | exit Failed | | + | | | | + +-------------+ +-------------+ + +When the second VM boots it will execute the script passed as userdata +automatically. The ping will be detected by periodically capturing the output +in the console-log of the second VM. + + +Tempest +^^^^^^^ + +Tempest `[2]`_ is the reference OpenStack Integration test suite. +It is a set of integration tests to be run against a live OpenStack cluster. +Tempest has suites of tests for: + + * OpenStack API validation + * Scenarios + * Other specific tests useful in validating an OpenStack deployment + +Functest uses Rally `[3]`_ to run the Tempest suite. +Rally generates automatically the Tempest configuration file **tempest.conf**. +Before running the actual test cases, +Functest creates the needed resources (user, tenant) and +updates the appropriate parameters into the configuration file. + +When the Tempest suite is executed, each test duration is measured and the full +console output is stored to a *log* file for further analysis. + +The Tempest testcases are distributed accross two +Tiers: + + * Smoke Tier - Test Case 'tempest_smoke_serial' + * Components Tier - Test case 'tempest_full_parallel' + +NOTE: Test case 'tempest_smoke_serial' executes a defined set of tempest smoke +tests with a single thread (i.e. serial mode). Test case 'tempest_full_parallel' +executes all defined Tempest tests using several concurrent threads +(i.e. parallel mode). The number of threads activated corresponds to the number +of available logical CPUs. + +The goal of the Tempest test suite is to check the basic functionalities of the +different OpenStack components on an OPNFV fresh installation, using the +corresponding REST API interfaces. + + +Rally bench test suites +^^^^^^^^^^^^^^^^^^^^^^^ + +Rally `[3]`_ is a benchmarking tool that answers the question: + +*How does OpenStack work at scale?* + +The goal of this test suite is to benchmark all the different OpenStack modules and +get significant figures that could help to define Telco Cloud KPIs. + +The OPNFV Rally scenarios are based on the collection of the actual Rally scenarios: + + * authenticate + * cinder + * glance + * heat + * keystone + * neutron + * nova + * quotas + * requests + +A basic SLA (stop test on errors) has been implemented. + +The Rally testcases are distributed accross two Tiers: + + * Smoke Tier - Test Case 'rally_sanity' + * Components Tier - Test case 'rally_full' + +NOTE: Test case 'rally_sanity' executes a limited number of Rally smoke test +cases. Test case 'rally_full' executes the full defined set of Rally tests. + +SNAPS +----- + +SNAPS stands for "SNA/NFV Application development Platform and Stack". +This project seeks to develop baseline OpenStack NFV installations. It has been +developed by Steven Pisarski and provided an object oriented library to perform +functional and performance tests. It has been declined in several test suites in +Functest, 2 are part of healthcheck tier, one belongs to smoke tier. + +connection check +^^^^^^^^^^^^^^^^ +Connection_check consists in 9 test cases (test duration < 5s) checking the +connectivity with Glance, Keystone, Neutron, Nova and the external network. + +api_check +^^^^^^^^^ +This test case verifies the retrieval of OpenStack clients: Keystone, Glance, +Neutron and Nova and may perform some simple queries. When the config value of +snaps.use_keystone is True, functest must have access to the cloud's private +network. +This suite consists in 49 tests (test duration< 2 minutes) + +snaps_smoke +^^^^^^^^^^^ +This test case contains tests that setup and destroy environments with VMs with +and without Floating IPs with a newly created user and project. Set the config +value snaps.use_floating_ips (True|False) to toggle this functionality. When +the config value of snaps.use_keystone is True, functest must have access +the cloud's private network. +This suite consists in 38 tests (test duration < 10 minutes) + +More information on SNAPS can be found in  `[13]`_ + + +SDN Controllers +--------------- + +There are currently 2 available controllers: + + * OpenDaylight (ODL) + * ONOS + +OpenDaylight +^^^^^^^^^^^^ + +The OpenDaylight (ODL) test suite consists of a set of basic tests inherited +from the ODL project using the Robot `[11]`_ framework. +The suite verifies creation and deletion of networks, subnets and ports with +OpenDaylight and Neutron. + +The list of tests can be described as follows: + + * Basic Restconf test cases + * Connect to Restconf URL + * Check the HTTP code status + + * Neutron Reachability test cases + * Get the complete list of neutron resources (networks, subnets, ports) + + * Neutron Network test cases + * Check OpenStack networks + * Check OpenDaylight networks + * Create a new network via OpenStack and check the HTTP status code returned by Neutron + * Check that the network has also been successfully created in OpenDaylight + + * Neutron Subnet test cases + * Check OpenStack subnets + * Check OpenDaylight subnets + * Create a new subnet via OpenStack and check the HTTP status code returned by Neutron + * Check that the subnet has also been successfully created in OpenDaylight + + * Neutron Port test cases + * Check OpenStack Neutron for known ports + * Check OpenDaylight ports + * Create a new port via OpenStack and check the HTTP status code returned by Neutron + * Check that the new port has also been successfully created in OpenDaylight + + * Delete operations + * Delete the port previously created via OpenStack + * Check that the port has been also succesfully deleted in OpenDaylight + * Delete previously subnet created via OpenStack + * Check that the subnet has also been successfully deleted in OpenDaylight + * Delete the network created via OpenStack + * Check that the network has also been succesfully deleted in OpenDaylight + +Note: the checks in OpenDaylight are based on the returned HTTP status +code returned by OpenDaylight. + + +ONOS +^^^^ + +TestON Framework is used to test the ONOS SDN controller functions. +The test cases deal with L2 and L3 functions. +The ONOS test suite can be run on any ONOS compliant scenario. + +The test cases are described as follows: + + * onosfunctest: The main executable file contains the initialization of + the docker environment and functions called by FUNCvirNetNB and + FUNCvirNetNBL3 + +

+checks, as part of an automated CI / CD platform delivery process. + +The project makes use of the existing SCAP format `[6]`_ to perform deep +scanning of NFVI nodes, to insure they are hardened and free of known CVE +reported vulnerabilities. + +The SCAP content itself, is then consumed and run using an upstream opensource tool +known as OpenSCAP `[7]`_. + +The OPNFV Security Group have developed the code that will called by the OPNFV Jenkins +build platform, to perform a complete scan.

Each 'test case' usually represents an actual +'Test Suite' comprised -in turn- of several test cases internally. + +Test cases also have an implicit execution order. For example, if the early +'healthcheck' Tier testcase fails, or if there are any failures in the 'smoke' +Tier testcases, there is little point to launch a full testcase execution round. + +In Danube, we merged smoke and sdn controller tiers in smoke tier. + +An overview of the Functest Structural Concept is depicted graphically below: + +.. figure:: ../images/concepts_mapping_final.png + :align: center + :alt: Functest Concepts Structure + +Some of the test cases are developed by Functest team members, whereas others +are integrated from upstream communities or other OPNFV projects. For example, +`Tempest <http://docs.openstack.org/developer/tempest/overview.html>`_ is the +OpenStack integration test suite and Functest is in charge of the selection, +integration and automation of those tests that fit suitably to OPNFV. + +The Tempest test suite is the default OpenStack smoke test suite but no new test +cases have been created in OPNFV Functest. + +The results produced by the tests run from CI are pushed and collected into a +NoSQL database. The goal is to populate the database with results from different +sources and scenarios and to show them on a `Functest Dashboard`_. A screenshot +of a live Functest Dashboard is shown below: + +** TODO ** +.. figure:: ../images/FunctestDashboardDanube.png + :align: center + :alt: Functest Dashboard + + +Basic components (VIM, SDN controllers) are tested through their own suites. +Feature projects also provide their own test suites with different ways of +running their tests. + +The notion of domain has been introduced in the description of the test cases +stored in the Database. +This parameters as well as possible tags can be used for the Test case catalog. + +vIMS test case was integrated to demonstrate the capability to deploy a +relatively complex NFV scenario on top of the OPNFV infrastructure. + +Functest considers OPNFV as a black box. As of Danube release the OPNFV +offers a lot of potential combinations: + + * 3 controllers (OpenDaylight, ONOS, OpenContrail) + * 4 installers (Apex, Compass, Fuel, Joid) + +Most of the tests are runnable by any combination, but some tests might have +restrictions imposed by the utilized installers or due to the available +deployed features. The system uses the environment variables (INSTALLER_IP and +DEPLOY_SCENARIO) to automatically determine the valid test cases, for each given +environment. + +A convenience Functest CLI utility is also available to simplify setting up the +Functest evironment, management of the OpenStack environment (e.g. resource +clean-up) and for executing tests. +The Functest CLI organised the testcase into logical Tiers, which contain in +turn one or more testcases. The CLI allows execution of a single specified +testcase, all test cases in a specified Tier, or the special case of execution +of **ALL** testcases.

In this particular system the deployment does not support the 'onos' SDN +Controller Test Case; for example. + +**Important** If you use the command 'functest tier run <tier_name>', then the +Functest CLI utility will call **all valid Test Cases**, which belong to the +specified Test Tier, as relevant to scenarios deployed to the SUT environment. +Thus, the Functest CLI utility calculates automatically which tests can be +executed and which cannot, given the environment variable **DEPLOY_SCENARIO**, +which is passed in to the Functest docker container. + +Currently, the Functest CLI command 'functest testcase run <testcase_name>', supports +two possibilities:: + + * Run a single Test Case, specified by a valid choice of <testcase_name> + * Run ALL test Test Cases (for all Tiers) by specifying <testcase_name> = 'all' + +Functest includes a cleaning mechanism in order to remove all the OpenStack +resources except those present before running any test. The script +*$REPOS_DIR/functest/functest/utils/generate_defaults.py* is called once when setting up +the Functest environment (i.e. CLI command 'functest env prepare') to snapshot +all the OpenStack resources (images, networks, volumes, security groups, tenants, +users) so that an eventual cleanup does not remove any of these defaults. + +The script **clean_openstack.py** which is located in +*$REPOS_DIR/functest/functest/utils/* is normally called after a test execution. It is +in charge of cleaning the OpenStack resources that are not specified in the +defaults file generated previously which is stored in +*/home/opnfv/functest/conf/os_defaults.yaml* in the Functest docker container. + +It is important to mention that if there are new OpenStack resources created +manually after preparing the Functest environment, they will be removed, unless +you use the special method of invoking the test case with specific suppression +of clean up. (See the `Troubleshooting`_ section). + +The reason to include this cleanup meachanism in Functest is because some +test suites such as Tempest or Rally create a lot of resources (users, +tenants, networks, volumes etc.) that are not always properly cleaned, so this +function has been set to keep the system as clean as it was before a +full Functest execution. + +Although the Functest CLI provides an easy way to run any test, it is possible to +do a direct call to the desired test script. For example: + + python $REPOS_DIR/functest/functest/opnfv_tests/OpenStack/vPing/vPing_ssh.py -d + + +Automated testing +----------------- + +As mentioned previously, the Functest Docker container preparation as well as +invocation of Test Cases can be called within the container from the Jenkins CI +system. There are 3 jobs that automate the whole process. The first job runs all +the tests referenced in the daily loop (i.e. that must been run daily), the second +job runs the tests referenced in the weekly loop (usually long duration tests run +once a week maximum) and the third job allows testing test suite by test suite specifying +the test suite name. The user may also use either of these Jenkins jobs to execute +the desired test suites. + +One of the most challenging task in the Danube release consists +in dealing with lots of scenarios and installers. Thus, when the tests are +automatically started from CI, a basic algorithm has been created in order to +detect whether a given test is runnable or not on the given scenario. +Some Functest test suites cannot be systematically run (e.g. ODL suite can not +be run on an ONOS scenario). The daily/weekly notion has been introduces in +Colorado in order to save CI time and avoid running systematically +long duration tests. It was not used in Colorado due to CI resource shortage. +The mechanism remains however as part of the CI evolution. + +CI provides some useful information passed to the container as environment +variables: + + * Installer (apex|compass|daisy|fuel|joid), stored in INSTALLER_TYPE + * Installer IP of the engine or VM running the actual deployment, stored in INSTALLER_IP + * The scenario [controller]-[feature]-[mode], stored in DEPLOY_SCENARIO with + + * controller = (odl|onos|ocl|nosdn) + * feature = (ovs(dpdk)|kvm|sfc|bgpvpn|multisites) + * mode = (ha|noha) + +The constraints per test case are defined in the Functest configuration file +*/home/opnfv/repos/functest/functest/ci/testcases.yaml*:: + + tiers: + - + name: healthcheck + order: 0 + ci_loop: '(daily)|(weekly)' + description : >- + First tier to be executed to verify the basic + operations in the VIM. + testcases: + - + name: healthcheck + criteria: 'status == "PASS"' + blocking: true + description: >- + This test case verifies the basic OpenStack services like + Keystone, Glance, Cinder, Neutron and Nova. + + dependencies: + installer: '' + scenario: '' + + - + name: smoke + order: 1 + ci_loop: '(daily)|(weekly)' + description : >- + Set of basic Functional tests to validate the OpenStack deployment. + testcases: + - + name: vping_ssh + criteria: 'status == "PASS"' + blocking: true + description: >- + This test case verifies: 1) SSH to an instance using floating + IPs over the public network. 2) Connectivity between 2 instances + over a private network. + dependencies: + installer: '' + scenario: '^((?!bgpvpn|odl_l3).)*$' + run: + module: 'functest.opnfv_tests.openstack.vping.vping_ssh' + class: 'VPingSSH' + .... + +We may distinguish 2 levels in the test case description: + * Tier level + * Test case level + +At the tier level, we define the following parameters: + + * ci_loop: indicate if in automated mode, the test case must be run in daily and/or weekly jobs + * description: a high level view of the test case + +For a given test case we defined: + * the name of the test case + * the criteria (experimental): a criteria used to declare the test case as PASS or FAIL + * blocking: if set to true, if the test is failed, the execution of the following tests is canceled + * the description of the test case + * the dependencies: a combination of 2 regex on the scenario and the installer name + * run: In Danube we introduced the notion of abstract class in order to harmonize the way to run internal, feature or vnf tests + +For further details on abstraction classes, see developper guide. + +Additional parameters have been added in the desription in the Database. +The target is to use the configuration stored in the Database and consider the +local file as backup if the Database is not reachable. +The additional fields related to a test case are: + * trust: we introduced this notion to put in place a mechanism of scenario promotion. + * Version: it indicates since which version you can run this test + * domains: the main domain covered by the test suite + * tags: a list of tags related to the test suite + +The order of execution is the one defined in the file if all test cases are selected. + +In CI daily job the tests are executed in the following order: + + 1) healthcheck (blocking) + 2) smoke: both vPings are blocking + 3) Feature project tests cases + +In CI weekly job we add 2 tiers: + + 4) VNFs (vIMS) + 5) Components (Rally and Tempest long duration suites) + +As explained before, at the end of an automated execution, the OpenStack resources +might be eventually removed. +Please note that a system snapshot is taken before any test case execution. + +This testcase.yaml file is used for CI, for the CLI and for the automatic reporting. diff --git a/docs/testing/user/userguide/troubleshooting.rst b/docs/testing/user/userguide/troubleshooting.rst new file mode 100644 index 00000000..84550191 --- /dev/null +++ b/docs/testing/user/userguide/troubleshooting.rst @@ -0,0 +1,387 @@ +..

There is one difference, between the Functest CLI based test case + execution compared to the earlier used Bash shell script, which is + relevant to point out in troubleshooting scenarios: + + The Functest CLI does **not yet** support the option to suppress + clean-up of the generated OpenStack resources, following the execution + of a test case. + + Explanation: After finishing the test execution, the corresponding + script will remove, by default, all created resources in OpenStack + (image, instances, network and security group). When troubleshooting, + it is advisable sometimes to keep those resources in case the test + fails and a manual testing is needed. + + It is actually still possible to invoke test execution, with suppression + of OpenStack resource cleanup, however this requires invocation of a + **specific Python script:** '/home/opnfv/repos/functest/ci/run_test.py'. + The `OPNFV Functest Developer Guide`_ provides guidance on the use of that + Python script in such troubleshooting cases. + +Some of the common errors that can appear in this test case are:: + + vPing_ssh- ERROR - There has been a problem when creating the neutron network.... + +This means that there has been some problems with Neutron, even before creating the +instances. Try to create manually a Neutron network and a Subnet to see if that works. +The debug messages will also help to see when it failed (subnet and router creation). +Example of Neutron commands (using 10.6.0.0/24 range for example):: + + neutron net-create net-test + neutron subnet-create --name subnet-test --allocation-pool start=10.6.0.2,end=10.6.0.100 \ + --gateway 10.6.0.254 net-test 10.6.0.0/24 + neutron router-create test_router + neutron router-interface-add <ROUTER_ID> test_subnet + neutron router-gateway-set <ROUTER_ID> <EXT_NET_NAME> + +Another related error can occur while creating the Security Groups for the instances:: + + vPing_ssh- ERROR - Failed to create the security group... + +In this case, proceed to create it manually. These are some hints:: + + neutron security-group-create sg-test + neutron security-group-rule-create sg-test --direction ingress --protocol icmp \ + --remote-ip-prefix 0.0.0.0/0 + neutron security-group-rule-create sg-test --direction ingress --ethertype IPv4 \ + --protocol tcp --port-range-min 80 --port-range-max 80 --remote-ip-prefix 0.0.0.0/0 + neutron security-group-rule-create sg-test --direction egress --ethertype IPv4 \ + --protocol tcp --port-range-min 80 --port-range-max 80 --remote-ip-prefix 0.0.0.0/0 + +The next step is to create the instances. The image used is located in +*/home/opnfv/functest/data/cirros-0.3.5-x86_64-disk.img* and a Glance image is created +with the name **functest-vping**. If booting the instances fails (i.e. the status +is not **ACTIVE**), you can check why it failed by doing:: + + nova list + nova show <INSTANCE_ID> + +It might show some messages about the booting failure. To try that manually:: + + nova boot --flavor m1.small --image functest-vping --nic net-id=<NET_ID> nova-test + +This will spawn a VM using the network created previously manually. +In all the OPNFV tested scenarios from CI, it never has been a problem with the +previous actions. Further possible problems are explained in the following sections. + + +vPing_SSH +^^^^^^^^^ +This test case creates a floating IP on the external network and assigns it to +the second instance **opnfv-vping-2**. The purpose of this is to establish +a SSH connection to that instance and SCP a script that will ping the first +instance. This script is located in the repository under +*$REPOS_DIR/functest/functest/opnfv_tests/OpenStack/vPing/ping.sh* and takes an IP as +a parameter. When the SCP is completed, the test will do an SSH call to that script +inside the second instance. Some problems can happen here:: + + vPing_ssh- ERROR - Cannot establish connection to IP xxx.xxx.xxx.xxx. Aborting + +If this is displayed, stop the test or wait for it to finish, if you have used +the special method of test invocation with specific supression of OpenStack +resource clean-up, as explained earler. It means that the Container can not +reach the Public/External IP assigned to the instance **opnfv-vping-2**. There +are many possible reasons, and they really depend on the chosen scenario. For +most of the ODL-L3 and ONOS scenarios this has been noticed and it is a known +limitation. + +First, make sure that the instance **opnfv-vping-2** succeeded to get an IP +from the DHCP agent. It can be checked by doing:: + + nova console-log opnfv-vping-2 + +If the message *Sending discover* and *No lease, failing* is shown, it probably +means that the Neutron dhcp-agent failed to assign an IP or even that it was not +responding. At this point it does not make sense to try to ping the floating IP. + +If the instance got an IP properly, try to ping manually the VM from the container:: + + nova list + <grab the public IP> + ping <public IP> + +If the ping does not return anything, try to ping from the Host where the Docker +container is running. If that solves the problem, check the iptable rules because +there might be some rules rejecting ICMP or TCP traffic coming/going from/to the +container. + +At this point, if the ping does not work either, try to reproduce the test +manually with the steps described above in the vPing common section with the +addition:: + + neutron floatingip-create <EXT_NET_NAME> + nova floating-ip-associate nova-test <FLOATING_IP> + + +Further troubleshooting is out of scope of this document, as it might be due to +problems with the SDN controller. Contact the installer team members or send an +email to the corresponding OPNFV mailing list for more information. + + + +vPing_userdata +^^^^^^^^^^^^^^ +This test case does not create any floating IP neither establishes an SSH +connection. Instead, it uses nova-metadata service when creating an instance +to pass the same script as before (ping.sh) but as 1-line text. This script +will be executed automatically when the second instance **opnfv-vping-2** is booted. + +The only known problem here for this test to fail is mainly the lack of support +of cloud-init (nova-metadata service). Check the console of the instance:: + + nova console-log opnfv-vping-2 + +If this text or similar is shown:: + + checking http://169.254.169.254/2009-04-04/instance-id + failed 1/20: up 1.13. request failed + failed 2/20: up 13.18. request failed + failed 3/20: up 25.20. request failed + failed 4/20: up 37.23. request failed + failed 5/20: up 49.25. request failed + failed 6/20: up 61.27. request failed + failed 7/20: up 73.29. request failed + failed 8/20: up 85.32. request failed + failed 9/20: up 97.34. request failed + failed 10/20: up 109.36. request failed + failed 11/20: up 121.38. request failed + failed 12/20: up 133.40. request failed + failed 13/20: up 145.43. request failed + failed 14/20: up 157.45. request failed + failed 15/20: up 169.48. request failed + failed 16/20: up 181.50. request failed + failed 17/20: up 193.52. request failed + failed 18/20: up 205.54. request failed + failed 19/20: up 217.56. request failed + failed 20/20: up 229.58. request failed + failed to read iid from metadata. tried 20 + +it means that the instance failed to read from the metadata service.
