4. Yardstick Installation

Yardstick supports installation by Docker or directly in Ubuntu. The installation procedure for Docker and direct installation are detailed in the sections 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 Yardstick flavor.
  4. Build a guest image and load it into the OpenStack environment.
  5. Create the test configuration .yaml file and run the test case/suite.

4.1. Prerequisites

The OPNFV deployment is out of the scope of this document and can be found in User Guide & Configuration Guide. The OPNFV platform is considered as the System Under Test (SUT) in this document.

Several prerequisites are needed for Yardstick:

  1. A Jumphost to run Yardstick on
  2. A Docker daemon or a virtual environment installed on the Jumphost
  3. A public/external network created on the SUT
  4. Connectivity from the Jumphost to the SUT public/external network

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.

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

If your Jumphost is operating behind a company http proxy and/or Firewall, please first consult Proxy Support section which is towards the end of this document. That section details some tips/tricks which may be of help in a proxified environment.

4.3. Install Yardstick directly in Ubuntu (second option)

Alternatively you can install Yardstick framework directly in Ubuntu or in an Ubuntu Docker image. No matter which way you choose to install Yardstick, the following installation steps are identical.

If you choose to use the Ubuntu Docker image, you can pull the Ubuntu Docker image from Docker hub:

sudo -EH docker pull ubuntu:16.04

4.3.1. Install Yardstick

Prerequisite preparation:

sudo -EH apt-get update && sudo -EH apt-get install -y \
   git python-setuptools python-pip
sudo -EH easy_install -U setuptools==30.0.0
sudo -EH pip install appdirs==1.4.0
sudo -EH pip install virtualenv

Download the source code and install Yardstick from it:

git clone https://gerrit.opnfv.org/gerrit/yardstick
export YARDSTICK_REPO_DIR=~/yardstick
cd ~/yardstick
sudo -EH ./install.sh

If the host is ever restarted, nginx and uwsgi need to be restarted:

service nginx restart
uwsgi -i /etc/yardstick/yardstick.ini

4.3.2. Configure the Yardstick environment (Todo)

For installing Yardstick directly in Ubuntu, the yardstick env command is not available. You need to prepare OpenStack environment variables and create Yardstick flavor and guest images manually.

4.3.3. Uninstall Yardstick

For uninstalling Yardstick, just delete the virtual environment:

rm -rf ~/yardstick_venv

4.4. Install Yardstick directly in OpenSUSE

You can install Yardstick framework directly in OpenSUSE.

4.4.1. Install Yardstick

Prerequisite preparation:

sudo -EH zypper -n install -y gcc \
   wget \
   git \
   sshpass \
   qemu-tools \
   kpartx \
   libffi-devel \
   libopenssl-devel \
   python \
   python-devel \
   python-virtualenv \
   libxml2-devel \
   libxslt-devel \
   python-setuptools-git

Create a virtual environment:

virtualenv ~/yardstick_venv
export YARDSTICK_VENV=~/yardstick_venv
source ~/yardstick_venv/bin/activate
sudo -EH easy_install -U setuptools

Download the source code and install Yardstick from it:

git clone https://gerrit.opnfv.org/gerrit/yardstick
export YARDSTICK_REPO_DIR=~/yardstick
cd yardstick
sudo -EH python setup.py install
sudo -EH pip install -r requirements.txt

Install missing python modules:

sudo -EH pip install pyyaml \
   oslo_utils \
   oslo_serialization \
   oslo_config \
   paramiko \
   python.heatclient \
   python.novaclient \
   python.glanceclient \
   python.neutronclient \
   scp \
   jinja2

4.4.2. Configure the Yardstick environment

Source the OpenStack environment variables:

source DEVSTACK_DIRECTORY/openrc

Export the Openstack external network. The default installation of Devstack names the external network public:

export EXTERNAL_NETWORK=public
export OS_USERNAME=demo

Change the API version used by Yardstick to v2.0 (the devstack openrc sets it to v3):

export OS_AUTH_URL=http://PUBLIC_IP_ADDRESS:5000/v2.0

4.4.3. Uninstall Yardstick

For unistalling Yardstick, just delete the virtual environment:

rm -rf ~/yardstick_venv

4.5. Verify the installation

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 yardstick-image can be found in OpenStack and the 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

Note

The above commands could be run in both the Yardstick container and the Ubuntu directly.

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.

4.6. Deploy InfluxDB and Grafana using Docker

Without InfluxDB, Yardstick stores results for running test case in the file /tmp/yardstick.out. However, it’s inconvenient to retrieve and display test results. So we will show how to use InfluxDB to store data and use Grafana to display data in the following sections.

4.6.2. Manual deployment of InfluxDB and Grafana containers

You can also deploy influxDB and Grafana containers manually on the Jumphost. The following sections show how to do.

Pull docker images:

sudo -EH docker pull tutum/influxdb
sudo -EH docker pull grafana/grafana

Run influxDB:

sudo -EH docker run -d --name influxdb \
   -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 \
   tutum/influxdb
docker exec -it influxdb bash

Configure influxDB:

influx
   >CREATE USER root WITH PASSWORD 'root' WITH ALL PRIVILEGES
   >CREATE DATABASE yardstick;
   >use yardstick;
   >show MEASUREMENTS;

Run Grafana:

sudo -EH docker run -d --name grafana -p 1948:3000 grafana/grafana

Log on http://{YOUR_IP_HERE}:1948 using admin/admin and configure database resource to be {YOUR_IP_HERE}:8086.

Grafana data source configuration

Configure yardstick.conf:

sudo -EH docker exec -it yardstick /bin/bash
sudo cp etc/yardstick/yardstick.conf.sample /etc/yardstick/yardstick.conf
sudo vi /etc/yardstick/yardstick.conf

Modify 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.

4.7. Deploy InfluxDB and Grafana directly in Ubuntu (Todo)

4.8. Proxy Support

To configure the Jumphost to access Internet through a proxy its necessary to export several variables to the environment, contained in the following script:

#!/bin/sh
_proxy=<proxy_address>
_proxyport=<proxy_port>
_ip=$(hostname -I | awk '{print $1}')

export ftp_proxy=http://$_proxy:$_proxyport
export FTP_PROXY=http://$_proxy:$_proxyport
export http_proxy=http://$_proxy:$_proxyport
export HTTP_PROXY=http://$_proxy:$_proxyport
export https_proxy=http://$_proxy:$_proxyport
export HTTPS_PROXY=http://$_proxy:$_proxyport
export no_proxy=127.0.0.1,localhost,$_ip,$(hostname),<.localdomain>
export NO_PROXY=127.0.0.1,localhost,$_ip,$(hostname),<.localdomain>

To enable Internet access from a container using docker, depends on the OS version. On Ubuntu 14.04 LTS, which uses SysVinit, /etc/default/docker must be modified:

.......
# If you need Docker to use an HTTP proxy, it can also be specified here.
export http_proxy="http://<proxy_address>:<proxy_port>/"
export https_proxy="https://<proxy_address>:<proxy_port>/"

Then its necessary to restart the docker service:

sudo -EH service docker restart

In Ubuntu 16.04 LTS, which uses Systemd, its necessary to create a drop-in directory:

sudo mkdir /etc/systemd/system/docker.service.d

Then, the proxy configuration will be stored in the following file:

# cat /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=https://<proxy_address>:<proxy_port>/"
Environment="HTTPS_PROXY=https://<proxy_address>:<proxy_port>/"
Environment="NO_PROXY=localhost,127.0.0.1,<localaddress>,<.localdomain>"

The changes need to be flushed and the docker service restarted:

sudo systemctl daemon-reload
sudo systemctl restart docker

Any container is already created won’t contain these modifications. If needed, stop and delete the container:

sudo docker stop yardstick
sudo docker rm yardstick

Warning

Be careful, the above rm command will delete the container completely. Everything on this container will be lost.

Then follow the previous instructions Prepare the Yardstick container to rebuild the Yardstick container.
