Pulling the Docker image ------------------------ Pull the Functest Docker image ('opnfv/functest') from the public dockerhub registry under the OPNFV account: [̀`dockerhub`_], with the following docker command:: docker pull opnfv/functest: where identifies a release of the Functest docker container image in the public Dockerhub registry. There are many tags created automatically by the CI mechanisms, and you must ensure you pull an image with the **correct tag** to match the OPNFV software release installed in your environment. All available tagged images can be seen from location [FunctestDockerTags_]. For example, when running on the first official release of the OPNFV Danube system platform, tag "danube.1.0" is needed. For the second and third releases, the tag "danube.2.0" and "danube.3.0" can be used respectively. Pulling other tags might cause some problems while running the tests. Docker images pulled without a tag specifier bear the implicitly assigned label "latest". 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.2.0 d2c174a91911 7 minutes ago 1.471 GB opnfv/functest danube.1.0 13fa54a1b238 4 weeks ago 1.29 GB 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. Please note that alpine dockers have been introduced in Euphrates. See alpine section for details. Accessing the Openstack credentials ----------------------------------- OpenStack credentials are mandatory and must be provided to Functest. When running the command "functest env prepare", the framework will automatically look for the Openstack credentials file "/home/opnfv/functest/conf/openstack.creds" and will exit with error if it is not present or it is empty. There are 2 ways to provide that file: * by using a Docker volume with -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 manually the file '/home/opnfv/functest/conf/openstack.creds' inside the running container and pasting the credentials in it. Consult your installer guide for further details. This is however not instructed in this document. There is a default environment variable in the Functest container **$creds** that points to the credentials absolute path to help the user with this task. 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=" # Use one of following apex, compass, fuel or joid #. Functest needs to know the IP of some installers:: -e "INSTALLER_IP=" These two env variables are useful extract some information from the deployment. However, for some test cases like SFC or Barometer they are mandatory since the tests need to access the installer node and the deployment. #. 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---" 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 "=" 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=" \ -e "BUILD_TAG=" \ -e "CI_DEBUG=" where: = 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. = 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 database from different Jenkins jobs. DO NOT USE THIS OPTION IN MANUAL TEST SCENARIOS. = "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. Installer Tips -------------- 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. This section will provide the guideline, the parameters values are defaults here, which should be adjusted according to the settings, the complete steps are given here so as not to appear too abruptly. 1, Pull Functest docker image from public dockerhub:: docker pull opnfv/functest: here can be "brahmaputra.1.0", "colorado.1.0", etc. Tag omitted means the latest docker image:: docker pull opnfv/functest 2, Functest Docker container creation To make a file used for the environment, such as 'functest-docker-env':: CINDER_ENDPOINT_TYPE=publicURL NOVA_ENDPOINT_TYPE=publicURL OS_ENDPOINT_TYPE=publicURL OS_INTERFACE=publicURL OS_USERNAME=admin OS_PASSWORD='990232e0885da343ac805523322d' OS_PROJECT_NAME=admin OS_TENANT_NAME=admin OS_AUTH_URL=https://192.16.1.222:5000/v3 OS_NO_CACHE=1 OS_USER_DOMAIN_NAME=Default OS_PROJECT_DOMAIN_NAME=Default OS_REGION_NAME=RegionOne OS_IDENTITY_API_VERSION=3 OS_AUTH_VERSION=3 Note: please adjust the content according to the environment, such as 'TENANT_ID' maybe used for some special cases. Then to create the Functest docker:: docker run --privileged=true --rm -t \ --env-file functest-docker-env \ --name \ opnfv/functest: /bin/bash 3, To attach Functest container Before trying to attach the Functest container, the status can be checked by:: docker ps -a to attach the 'Up' status Functest container and start bash mode:: docker exec -it bash 4, Functest environment preparation and check To see the Section below `Preparing the Functest environment`_. Functest docker container directory structure --------------------------------------------- Inside the Functest docker container, the following directory structure should now be in place:: `-- home | `-- opnfv | |-- functest | | |-- conf | | |-- data | | |-- images | | `-- results | `-- repos | |-- onos | |-- doctor | `-- vnfs -- src |-- tempest |-- vims-test |-- odl_test `-- fds Underneath the '/home/opnfv/' directory, the Functest docker container includes two main directories: * The **functest** directory stores configuration files (e.g. the OpenStack creds are stored in path '/home/opnfv/functest/conf/openstack.creds'), the **data** directory stores a 'cirros' test image used in some functional tests and the **results** directory stores some temporary result log files * The **repos** directory holds various repositories. The directories are used for the installation of the needed tooling (e.g. rally) or for the retrieval of feature projects scenarios (e.g. promise) The structure under the **functest** repository can be described as follows:: |-- INFO |-- LICENSE |-- api | `-- apidoc |-- build.sh |-- commons | |-- docker | |-- Dockerfile | |-- Dockerfile.aarch64.patch | |-- components | |-- config_install_env.sh | |-- core | |-- docker_remote_api | |-- features | |-- healthcheck | |-- smoke | |-- vnf | `-- thirdparty-requirements.txt |-- docs | |-- com | |-- images | |-- release | | `-- release-notes | |-- results | | testing | | |-- developer | | `-- user | | |-- configguide | | `-- userguide `-- functest |-- api | |-- base.py | |-- server.py | |-- urls.py | |-- common | | |-- api_utils.py | | `-- error.py | `-- resources | `-- v1 | |-- creds.py | |-- envs.py | |-- testcases.py | `-- tiers.py |-- ci │   |-- check_deployment.py │   |-- config_aarch64_patch.yaml │   |-- config_functest.yaml │   |-- config_patch.yaml │   |-- download_images.sh │   |-- installer_params.yaml │   |-- logging.ini │   |-- prepare_env.py │   |-- rally_aarch64_patch.conf │   |-- run_tests.py │   |-- testcases.yaml │   |-- tier_builder.py │   `-- tier_handler.py |-- cli │   |-- cli_base.py │   |-- commands │   │   |-- cli_env.py │   │   |-- cli_os.py │   │   |-- cli_testcase.py │   │   `-- cli_tier.py │   |-- functest-complete.sh |-- core │   |-- feature.py │   |-- testcase.py │   |-- unit.py │   `-- vnf.py |-- energy │   |-- energy.py │   `-- energy.pyc |-- opnfv_tests │   |-- mano │   │   |-- orchestra.py │   |-- openstack │   │   |-- rally │   │   |-- refstack_client │   │   |-- snaps │   │   |-- tempest │   │   `-- vping │   |-- sdn │   │   |-- odl │   │   `-- onos │   `-- vnf │   |-- aaa │   |-- ims │   `-- router |-- tests │   `-- unit │   |-- ci │   |-- cli │   |-- core │   |-- energy │   |-- features │   |-- odl │   |-- openstack │   |-- opnfv_tests │   |-- test_utils.py │   |-- utils │   `-- vnf |-- utils | |-- config.py | |-- constants.py | |-- decorators.py | |-- env.py | |-- functest_utils.py | |-- functest_vacation.py | |-- openstack_clean.py | |-- openstack_snapshot.py | |-- openstack_tacker.py | `-- openstack_utils.py |-- requirements.txt |-- setup.cfg |-- setup.py |-- test-requirements.txt |-- tox.ini |-- upper-constraints.txt (Note: All *.pyc files removed from above list for brevity...) We may distinguish several directories, the first level has 5 directories: * **api**: This directory is dedicated for the internal Functest API and the API (framework) documentations. * **commons**: This directory is dedicated for storage of traffic profile or any other test inputs that could be reused by any test project. * **docker**: This directory includes the needed files and tools to build the Functest Docker image. * **docs**: This directory includes documentation: Release Notes, User Guide, Configuration Guide and Developer Guide. * **functest**: This directory contains all the code needed to run functest internal cases and OPNFV onboarded feature or VNF test cases. Functest directory has 6 directories: * **ci**: This directory contains test structure definition files (e.g .yaml) and bash shell/python scripts used to configure and execute Functional tests. The test execution script can be executed under the control of Jenkins CI jobs. * **cli**: This directory holds the python based Functest CLI utility source code, which is based on the Python 'click' framework. * **core**: This directory holds the python based Functest core source code. Three abstraction classes have been created to ease the integration of internal, feature or vnf cases. * **opnfv_tests**: This directory includes the scripts required by Functest internal test cases and other feature projects test cases. * **tests**: This directory includes the functest unit tests * **utils**: this directory holds Python source code for some general purpose helper utilities, which testers can also re-use in their own test code. See for an example the Openstack helper utility: 'openstack_utils.py'. Useful Docker commands ---------------------- When typing **exit** in the container prompt, this will cause exiting the container and probably stopping it. When stopping a running Docker container all the changes will be lost, there is a keyboard shortcut to quit the container without stopping it: -P + -Q. To reconnect to the running container **DO NOT** use the *run* command again (since it will create a new container), use the *exec* or *attach* command instead:: docker ps # docker exec -ti /bin/bash There are other useful Docker commands that might be needed to manage possible issues with the containers. List the running containers:: docker ps List all the containers including the stopped ones:: docker ps -a Start a stopped container named "FunTest":: docker start FunTest Attach to a running container named "StrikeTwo":: docker attach StrikeTwo It is useful sometimes to remove a container if there are some problems:: docker rm Use the *-f* option if the container is still running, it will force to destroy it:: docker rm -f Check the Docker documentation [`dockerdocs`_] for more information. Preparing the Functest environment ---------------------------------- Once the Functest docker container is up and running, the required Functest environment needs to be prepared. 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`_ 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 environment, 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. The value is set by Jenkins CI. Finally, the **functest** CLI has a **--help** options: Some examples:: functest --help Usage: functest [OPTIONS] COMMAND [ARGS]... Options: --version Show the version and exit. -h, --help Show this message and exit. Commands: env openstack testcase tier functest env --help Usage: functest env [OPTIONS] COMMAND [ARGS]... Options: -h, --help Show this message and exit. Commands: prepare Prepares the Functest environment. show Shows information about the current... status Checks if the Functest environment is ready... Checking Openstack and credentials ---------------------------------- It is recommended and fairly straightforward to check that Openstack and credentials are working as expected. Once the credentials are there inside the container, they should be sourced before running any Openstack commands:: source /home/opnfv/functest/conf/openstack.creds After this, try to run any OpenStack command to see if you get any output, for instance:: openstack user list This will return a list of the actual users in the OpenStack deployment. 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 :/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="" export https_proxy="" 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 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. You can use the **curl** command instead. curl http://www.opnfv.org:80 curl https://www.opnfv.org:443 (Ignore the content. If command returns a valid HTML page, it proves the connection.) Docker Installation on CentOS behind http proxy ----------------------------------------------- This section is applicable for CentOS family OS on Jumphost which itself is behind a proxy server. In that case, the instructions below should be followed **before** installing the docker engine:: 1) # Make a directory '/etc/systemd/system/docker.service.d' # if it does not exist sudo mkdir /etc/systemd/system/docker.service.d 2) # Create a file called 'env.conf' in that directory with # the following contents: [Service] EnvironmentFile=-/etc/sysconfig/docker 3) # Set up a file called 'docker' in directory '/etc/sysconfig' # with the following contents: HTTP_PROXY="" HTTPS_PROXY="" http_proxy="${HTTP_PROXY}" https_proxy="${HTTPS_PROXY}" 4) # Reload the daemon systemctl daemon-reload 5) # Sanity check - check the following docker settings: systemctl show docker | grep -i env Expected result: ---------------- EnvironmentFile=/etc/sysconfig/docker (ignore_errors=yes) DropInPaths=/etc/systemd/system/docker.service.d/env.conf Now follow the instructions in [`InstallDockerCentOS`_] to download and install the **docker-engine**. The instructions conclude with a "test pull" of a sample "Hello World" docker container. This should now work with the above pre-requisite actions. Installation and Configuration (Alpine) ======================================= Introduction to Alpine ---------------------- Alpine container have been introduced in Euphrates and released as experimental. Alpine allows Functest testing in several very light container and thanks to the refactoring on dependency management shoudl allow the creation of light and fully customized docker files Functest Alpine --------------- Docker files are available on the the dockerhub: * opnfv/functest-core * opnfv/functest-healthcheck * opnfv/functest-smoke * opnfv/functest-features * opnfv/functest-components * opnfv/functest-vnf Preparing your environment -------------------------- cat env:: INSTALLER_TYPE=XXX INSTALLER_IP=XXX EXTERNAL_NETWORK=XXX cat openstack.creds:: export OS_AUTH_URL=XXX export OS_USER_DOMAIN_NAME=XXX export OS_PROJECT_DOMAIN_NAME=XXX export OS_USERNAME=XXX export OS_TENANT_NAME=XXX export OS_PROJECT_NAME=XXX export OS_PASSWORD=XXX export OS_VOLUME_API_VERSION=XXX export OS_IDENTITY_API_VERSION=XXX export OS_IMAGE_API_VERSION=XXX md5sum images/*md5sum images/*:: c03e55c22b6fb2127e7de391b488d8d6 `images/CentOS-7-x86_64-GenericCloud.qcow2`_ f8ab98ff5e73ebab884d80c9dc9c7290 `images/cirros-0.3.5-x86_64-disk.img`_ 845c9b0221469f9e0f4d7ea0039ab5f2 `images/ubuntu-14.04-server-cloudimg-amd64-disk1.img`_ .. _`dockerdocs`: https://docs.docker.com/ .. _`dockerhub`: https://hub.docker.com/r/opnfv/functest/ .. _`Proxy`: https://docs.docker.com/engine/admin/systemd/#http-proxy .. _`FunctestDockerTags`: https://hub.docker.com/r/opnfv/functest/tags/ .. _`InstallDockerCentOS`: https://docs.docker.com/engine/installation/linux/centos/ .. _`Functest User Guide`: http://docs.opnfv.org/en/stable-danube/submodules/functest/docs/testing/user/userguide/index.html :: _`images/CentOS-7-x86_64-GenericCloud.qcow2` http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img :: _`images/cirros-0.3.5-x86_64-disk.img` https://cloud-images.ubuntu.com/releases/14.04/release/ubuntu-14.04-server-cloudimg-amd64-disk1.img :: _`images/ubuntu-14.04-server-cloudimg-amd64-disk1.img` https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2
