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 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Install dependencies: :: sudo apt-get update && sudo apt-get install -y \ wget \ git \ sshpass \ qemu-utils \ kpartx \ libffi-dev \ libssl-dev \ python \ python-dev \ python-virtualenv \ libxml2-dev \ libxslt1-dev \ python-setuptools Create a python virtual environment, source it and update setuptools: :: virtualenv ~/yardstick_venv source ~/yardstick_venv/bin/activate easy_install -U setuptools Download source code and install python dependencies: :: git clone https://gerrit.opnfv.org/gerrit/yardstick cd yardstick python setup.py install A Youtube video tutorial on this installation mode is available at: http://www.youtube.com/watch?v=4S4izNolmR0 .. image:: http://img.youtube.com/vi/4S4izNolmR0/0.jpg :alt: http://www.youtube.com/watch?v=4S4izNolmR0 :target: http://www.youtube.com/watch?v=4S4izNolmR0 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-trusty-server --is-public true \ --disk-format qcow2 --container-format bare \ --file /tmp/workspace/yardstick/yardstick-trusty-server.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 suite. 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.
