Below is an example invocation of Yardstick plugin command and Storperf plug-in sample. Installing Storperf into Yardstick ================================== Storperf is delivered as a Docker container from https://hub.docker.com/r/opnfv/storperf/tags/. There are two possible methods for installation in your environment: * Run container on Jump Host * Run container in a VM In this introduction we will install Storperf on Jump Host. Step 0: Environment preparation ------------------------------- Running Storperf on Jump Host Requirements: * Docker must be installed * Jump Host must have access to the OpenStack Controller API * Jump Host must have internet connectivity for downloading docker image * Enough floating IPs must be available to match your agent count Before installing Storperf into yardstick you need to check your openstack environment and other dependencies: 1. Make sure docker is installed. 2. Make sure Keystone, Nova, Neutron, Glance, Heat are installed correctly. 3. Make sure Jump Host have access to the OpenStack Controller API. 4. Make sure Jump Host must have internet connectivity for downloading docker image. 5. You need to know where to get basic openstack Keystone authorization info, such as OS_PASSWORD, OS_PROJECT_NAME, OS_AUTH_URL, OS_USERNAME. 6. To run a Storperf container, you need to have OpenStack Controller environment variables defined and passed to Storperf container. The best way to do this is to put environment variables in a "storperf_admin-rc" file. The storperf_admin-rc should include credential environment variables at least: * OS_AUTH_URL * OS_USERNAME * OS_PASSWORD * OS_PROJECT_NAME * OS_PROJECT_ID * OS_USER_DOMAIN_ID *Yardstick* has a ``prepare_storperf_admin-rc.sh`` script which can be used to generate the ``storperf_admin-rc`` file, this script is located at ``test/ci/prepare_storperf_admin-rc.sh`` :: #!/bin/bash # Prepare storperf_admin-rc for StorPerf. AUTH_URL=${OS_AUTH_URL} USERNAME=${OS_USERNAME:-admin} PASSWORD=${OS_PASSWORD:-console} # OS_TENANT_NAME is still present to keep backward compatibility with legacy # deployments, but should be replaced by OS_PROJECT_NAME. TENANT_NAME=${OS_TENANT_NAME:-admin} PROJECT_NAME=${OS_PROJECT_NAME:-$TENANT_NAME} PROJECT_ID=`openstack project show admin|grep '\bid\b' |awk -F '|' '{print $3}'|sed -e 's/^[[:space:]]*//'` USER_DOMAIN_ID=${OS_USER_DOMAIN_ID:-default} rm -f ~/storperf_admin-rc touch ~/storperf_admin-rc echo "OS_AUTH_URL="$AUTH_URL >> ~/storperf_admin-rc echo "OS_USERNAME="$USERNAME >> ~/storperf_admin-rc echo "OS_PASSWORD="$PASSWORD >> ~/storperf_admin-rc echo "OS_PROJECT_NAME="$PROJECT_NAME >> ~/storperf_admin-rc echo "OS_PROJECT_ID="$PROJECT_ID >> ~/storperf_admin-rc echo "OS_USER_DOMAIN_ID="$USER_DOMAIN_ID >> ~/storperf_admin-rc The generated ``storperf_admin-rc`` file will be stored in the root directory. If you installed *Yardstick* using Docker, this file will be located in the container. You may need to copy it to the root directory of the Storperf deployed host. Step 1: Plug-in configuration file preparation ---------------------------------------------- To install a plug-in, first you need to prepare a plug-in configuration file in YAML format and store it in the "plugin" directory. The plugin configration file work as the input of yardstick "plugin" command. Below is the Storperf plug-in configuration file sample: :: --- # StorPerf plugin configuration file # Used for integration StorPerf into Yardstick as a plugin schema: "yardstick:plugin:0.1" plugins: name: storperf deployment: ip: 192.168.23.2 user: root password: root In the plug-in configuration file, you need to specify the plug-in name and the plug-in deployment info, including node ip, node login username and password. Here the Storperf will be installed on IP 192.168.23.2 which is the Jump Host in my local environment. Step 2: Plug-in install/remove scripts preparation -------------------------------------------------- In ``yardstick/resource/scripts`` directory, there are two folders: an ``install`` folder and a ``remove`` folder. You need to store the plug-in install/remove scripts in these two folders respectively. The detailed installation or remove operation should de defined in these two scripts. The name of both install and remove scripts should match the plugin-in name that you specified in the plug-in configuration file. For example, the install and remove scripts for Storperf are both named ``storperf.bash``. Step 3: Install and remove Storperf ----------------------------------- To install Storperf, simply execute the following command:: # Install Storperf yardstick plugin install plugin/storperf.yaml Removing Storperf from yardstick ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ To remove Storperf, simply execute the following command:: # Remove Storperf yardstick plugin remove plugin/storperf.yaml What yardstick plugin command does is using the username and password to log into the deployment target and then execute the corresponding install or remove script.
