Installing a plug-in into yardstick
===================================
Abstract
========
Yardstick currently provides a ``plugin`` CLI command to support integration
with other OPNFV testing projects. 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_TENANT_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_TENANT_ID
* OS_TENANT_NAME
* OS_PROJECT_NAME
* OS_USERNAME
* OS_PASSWORD
* OS_REGION_NAME
For this storperf_admin-rc file, during environment preparation a "prepare_storperf_admin-rc.sh"
script can be used to generate it.
::
#!/bin/bash
AUTH_URL=${OS_AUTH_URL}
USERNAME=${OS_USERNAME:-admin}
PASSWORD=${OS_PASSWORD:-console}
TENANT_NAME=${OS_TENANT_NAME:-admin}
VOLUME_API_VERSION=${OS_VOLUME_API_VERSION:-2}
PROJECT_NAME=${OS_PROJECT_NAME:-$TENANT_NAME}
TENANT_ID=`keystone tenant-get admin|grep 'id'|awk -F '|' '{print $3}'|sed -e 's/^[[:space:]]*//'`
rm -f ~/storperf_admin-rc
touch ~/storperf_admin-rc
echo "OS_AUTH_URL="$AUTH_URL >> ~/storperf_admin-rc
echo "OS_USERNAME="$USERNAME >> ~/storperf_admin-rc
echo "OS_PASSWORD="$PASSWORD >> ~/storperf_admin-rc
echo "OS_TENANT_NAME="$TENANT_NAME >> ~/storperf_admin-rc
echo "OS_VOLUME_API_VERSION="$VOLUME_API_VERSION >> ~/storperf_admin-rc
echo "OS_PROJECT_NAME="$PROJECT_NAME >> ~/storperf_admin-rc
echo "OS_TENANT_ID="$TENANT_ID >> ~/storperf_admin-rc
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
++++++++++++++++++++++++++++++++++++++++++++++++++
Under "yardstick/resource/scripts directory", there are two folders: a "install"
folder and a "remove" folder. You need to store the plug-in install/remove script
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 to "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.
