+Yardstick Installation
+======================
+
+Abstract
+--------
+
+Yardstick supports installation on Ubuntu 14.04 or via a Docker image. 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.
+
