What is Rally-OpenSack/xRally-OpenStack

Rally is tool & framework that allows one to write simple plugins and combine them in complex tests scenarios that allows to perform all kinds of testing!

Rally-OpenStack is a package of Rally plugins for OpenStack platform.

How to run and use xrally-openstack container

First of all, you need to pull the container. We suggest to use the last tagged version:

# pull the 2.2.0 image (the latest release at the point of writing the note)
$ docker pull xrally/xrally-openstack:2.2.0

WARNING: never attach folders and volumes to /rally inside the container. It can break everything.

The default configuration file is located at /etc/rally/rally.conf. You should not be aware of it. If you want to override some options, use /home/rally/.rally/rally.conf location instead. Rally does not load all configuration files, so the primary one will be used.

The default place for rally database file is /home/rally/.rally/rally.sqlite. To make the storage persistent across all container runs, you may want to use docker volumes or mount the directory.

• use docker volumes. It is the easiest way. You just need to do something like:

  $ docker volume create --name rally_volume
  $ docker run -v rally_volume:/home/rally/.rally xrally/xrally-openstack:2.2.0 env create --name "foo"
  

• mount outer directory inside the container

  # you can create directory in whatever you want to place, but you
  # may wish to make the data available for all users
  $ sudo mkdir /var/lib/rally_container
  
  # In order for the directory to be accessible by the Rally user
  # (uid: 65500) inside the container, it must be accessible by UID
  # 65500 *outside* the container as well, which is why it is created
  # in ``/var/lib/rally_container``. Creating it in your home directory is
  # only likely to work if your home directory has excessively open
  # permissions (e.g., ``0755``), which is not recommended.
  $ sudo chown 65500 /var/lib/rally_container
  
  # As opposed to mounting docker image, you must initialize rally database*
  $ docker run -v /var/lib/rally_container:/home/rally/.rally xrally/xrally-openstack:2.2.0 db create
  
  # And finally, you can start doing your things.*
  $ docker run -v /var/lib/rally_container:/home/rally/.rally xrally/xrally-openstack:2.2.0 env create --name "foo"
  

Have fun!
