The +installation procedure on Ubuntu 14.04 or via the docker image are detailed in +the section below. + +To use Yardstick you should have access to an OpenStack environment, with at +least Nova, Neutron, Glance, Keystone and Heat installed. + +The steps needed to run Yardstick are: + +1. Install Yardstick. +2. Load OpenStack environment variables. +3. Create a Neutron external network. +4. Build Yardstick flavor and a guest image. +5. Load the guest image into the OpenStack environment. +6. Create the test configuration .yaml file. +7. Run the test case. + + +Prerequisites +------------- + +The OPNFV deployment is out of the scope of this document but it can be +found in http://artifacts.opnfv.org/opnfvdocs/colorado/docs/configguide/index.html. +The OPNFV platform is considered as the System Under Test (SUT) in this +document. + +Several prerequisites are needed for Yardstick: + + #. A Jumphost to run Yardstick on + #. A Docker daemon shall be installed on the Jumphost + #. A public/external network created on the SUT + #. Connectivity from the Jumphost to the SUT public/external 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 Yardstick. 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. + + +Installing Yardstick on Ubuntu 14.04 +------------------------------------ + +.. _install-framework: + +You can install Yardstick framework directly on Ubuntu 14.04 or in an Ubuntu +14.04 Docker image. No matter which way you choose to install Yardstick +framework, the following installation steps are identical. + +If you choose to use the Ubuntu 14.04 Docker image, You can pull the Ubuntu +14.04 Docker image from Docker hub: + +:: + + docker pull ubuntu:14.04 + +Installing Yardstick framework +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Download source code and install python dependencies: + +:: + + git clone https://gerrit.opnfv.org/gerrit/yardstick + cd yardstick + ./install.sh + + +Installing Yardstick using Docker +--------------------------------- + +Yardstick has a Docker image, this Docker image (**Yardstick-stable**) +serves as a replacement for installing the Yardstick framework in a virtual +environment (for example as done in :ref:`install-framework`). +It is recommended to use this Docker image to run Yardstick test. + +Pulling the Yardstick Docker image +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +.. _dockerhub: https://hub.docker.com/r/opnfv/yardstick/ + +Pull the Yardstick Docker image ('opnfv/yardstick') from the public dockerhub +registry under the OPNFV account: [dockerhub_], with the following docker +command:: + + docker pull opnfv/yardstick:stable + +After pulling the Docker image, check that it is available with the +following docker command:: + + [yardsticker@jumphost ~]$ docker images + REPOSITORY TAG IMAGE ID CREATED SIZE + opnfv/yardstick stable a4501714757a 1 day ago 915.4 MB + +Run the Docker image: + +:: + + docker run --privileged=true -it opnfv/yardstick:stable /bin/bash + +In the container the Yardstick repository is located in the /home/opnfv/repos +directory. + + +OpenStack parameters and credentials +------------------------------------ + +Environment variables +^^^^^^^^^^^^^^^^^^^^^ +Before running Yardstick it is necessary to export OpenStack environment variables +from the OpenStack *openrc* file (using the ``source`` command) and export the +external network name ``export EXTERNAL_NETWORK="external-network-name"``, +the default name for the external network is ``net04_ext``. + +Credential environment variables in the *openrc* file have to include at least: + +* OS_AUTH_URL +* OS_USERNAME +* OS_PASSWORD +* OS_TENANT_NAME + +A sample openrc file may look like this: + +* export OS_PASSWORD=console +* export OS_TENANT_NAME=admin +* export OS_AUTH_URL=http://172.16.1.222:35357/v2.0 +* export OS_USERNAME=admin +* export OS_VOLUME_API_VERSION=2 +* export EXTERNAL_NETWORK=net04_ext + + +Yardstick falvor and guest images +--------------------------------- + +Before executing Yardstick test cases, make sure that yardstick guest image and +yardstick flavor are available in OpenStack. +Detailed steps about creating yardstick flavor and building yardstick-trusty-server +image can be found below. + +Yardstick-flavor +^^^^^^^^^^^^^^^^ +Most of the sample test cases in Yardstick are using an OpenStack flavor called +*yardstick-flavor* which deviates from the OpenStack standard m1.tiny flavor by the +disk size - instead of 1GB it has 3GB. Other parameters are the same as in m1.tiny. + +Create yardstick-flavor: + +:: + + nova flavor-create yardstick-flavor 100 512 3 1 + + +.. _guest-image: + +Building a guest image +^^^^^^^^^^^^^^^^^^^^^^ +Most of the sample test cases in Yardstick are using a guest image called +*yardstick-trusty-server* which deviates from an Ubuntu Cloud Server image +containing all the required tools to run test cases supported by Yardstick. +Yardstick has a tool for building this custom image. It is necessary to have +sudo rights to use this tool. + +Also you may need install several additional packages to use this tool, by +follwing the commands below: + +:: + + apt-get update && apt-get install -y \ + qemu-utils \ + kpartx + +This image can be built using the following command while in the directory where +Yardstick is installed (``~/yardstick`` if the framework is installed +by following the commands above): + +:: + + export YARD_IMG_ARCH="amd64" + sudo echo "Defaults env_keep += \"YARD_IMG_ARCH\"" >> /etc/sudoers + sudo ./tools/yardstick-img-modify tools/ubuntu-server-cloudimg-modify.sh + +**Warning:** the script will create files by default in: +``/tmp/workspace/yardstick`` and the files will be owned by root! + +If you are building this guest image in inside a docker container make sure the +container is granted with privilege. + +The created image can be added to OpenStack using the ``glance image-create`` or +via the OpenStack Dashboard. + +Example command: + +:: + + glance --os-image-api-version 1 image-create \ + --name yardstick-image --is-public true \ + --disk-format qcow2 --container-format bare \ + --file /tmp/workspace/yardstick/yardstick-image.img + +Some Yardstick test cases use a Cirros image, you can find one at +http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img + + +Automatic flavor and image creation +----------------------------------- +Yardstick has a script for automatic creating yardstick flavor and building +guest images. This script is mainly used in CI, but you can still use it in +your local environment. + +Example command: + +:: + + export YARD_IMG_ARCH="amd64" + sudo echo "Defaults env_keep += \"YARD_IMG_ARCH\"" >> /etc/sudoers + source $YARDSTICK_REPO_DIR/tests/ci/load_images.sh + + +Yardstick default key pair +^^^^^^^^^^^^^^^^^^^^^^^^^^ +Yardstick uses a SSH key pair to connect to the guest image. This key pair can +be found in the ``resources/files`` directory. To run the ``ping-hot.yaml`` test +sample, this key pair needs to be imported to the OpenStack environment. + + +Examples and verifying the install +---------------------------------- + +It is recommended to verify that Yardstick was installed successfully +by executing some simple commands and test samples. Before executing yardstick +test cases make sure yardstick flavor and building yardstick-trusty-server +image can be found in glance and openrc file is sourced. Below is an example +invocation of yardstick help command and ping.py test sample: +:: + + yardstick –h + yardstick task start samples/ping.yaml + +Each testing tool supported by Yardstick has a sample configuration file. +These configuration files can be found in the **samples** directory. + +Default location for the output is ``/tmp/yardstick.out``. + + +Deploy InfluxDB and Grafana locally +------------------------------------ + +.. pull docker images + +Pull docker images + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +:: + + docker pull tutum/influxdb + docker pull grafana/grafana + +Run influxdb and config +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Run influxdb +:: + + docker run -d --name influxdb \ + -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 \ + tutum/influxdb + docker exec -it influxdb bash + +Config influxdb +:: + + influx + >CREATE USER root WITH PASSWORD 'root' WITH ALL PRIVILEGES + >CREATE DATABASE yardstick; + >use yardstick; + >show MEASUREMENTS; + +Run grafana and config +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Run grafana +:: + + docker run -d --name grafana -p 3000:3000 grafana/grafana + +Config grafana +:: + + http://{YOUR_IP_HERE}:3000 + log on using admin/admin and config database resource to be {YOUR_IP_HERE}:8086 + +.. image:: images/Grafana_config.png + :width: 800px + :alt: Grafana data source configration + +Config yardstick conf +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +cp ./etc/yardstick/yardstick.conf.sample /etc/yardstick/yardstick.conf + +vi /etc/yardstick/yardstick.conf +Config yardstick.conf +:: + + [DEFAULT] + debug = True + dispatcher = influxdb + + [dispatcher_influxdb] + timeout = 5 + target = http://{YOUR_IP_HERE}:8086 + db_name = yardstick + username = root + password = root + +Now you can run yardstick test cases and store the results in influxdb +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + + +Create a test suite for yardstick +------------------------------------ + +A test suite in yardstick is a yaml file which include one or more test cases. +Yardstick is able to support running test suite task, so you can customize you +own test suite and run it in one task. + +"tests/opnfv/test_suites" is where yardstick put ci test-suite. A typical test +suite is like below: + +fuel_test_suite.yaml + +:: + + --- + # Fuel integration test task suite + + schema: "yardstick:suite:0.1" + + name: "fuel_test_suite" + test_cases_dir: "samples/" + test_cases: + - + file_name: ping.yaml + - + file_name: iperf3.yaml + +As you can see, there are two test cases in fuel_test_suite, the syntax is simple +here, you must specify the schema and the name, then you just need to list the +test cases in the tag "test_cases" and also mark their relative directory in the +tag "test_cases_dir". + +Yardstick test suite also support constraints and task args for each test case. +Here is another sample to show this, which is digested from one big test suite. + +os-nosdn-nofeature-ha.yaml + +:: + + --- + + schema: "yardstick:suite:0.1" + + name: "os-nosdn-nofeature-ha" + test_cases_dir: "tests/opnfv/test_cases/" + test_cases: + - + file_name: opnfv_yardstick_tc002.yaml + - + file_name: opnfv_yardstick_tc005.yaml + - + file_name: opnfv_yardstick_tc043.yaml + constraint: + installer: compass + pod: huawei-pod1 + task_args: + huawei-pod1: '{"pod_info": "etc/yardstick/.../pod.yaml", + "host": "node4.LF","target": "node5.LF"}' + +As you can see in test case "opnfv_yardstick_tc043.yaml", there are two tags, "constraint" and +"task_args". "constraint" is where you can specify which installer or pod it can be run in +the ci environment. "task_args" is where you can specify the task arguments for each pod. + +All in all, to create a test suite in yardstick, you just need to create a suite yaml file +and add test cases and constraint or task arguments if necessary. + -- cgit 1.2.3-korg
