Jimmy McCrory 4c1eff91cd Add service specific rabbitmq vars 
Each service role makes use of its own *_rabbitmq_servers and
*_rabbitmq_port variables. Include these for glance, keystone, nova, and
neutron and default them to the previously set rabbitmq_servers and
rabbitmq_port variables.

OpenStack-Ansible testing

This is a PoC for centralizing the testing within OpenStack-Ansible. Aiming to move out the common pieces so that changes that affect testing don't have to occur in every single repository. This allows you to run the common set of plays based on your requirements, and will work based on the inventory specs. The aim is to avoid (as much as possible) the requirement to change the same thing in 50 different places.

Steps so far:

  1. Move out playbooks for role installs
  2. Move out variables to become a test-default vars.
  3. Genericize rolename calls

General notes

I've patched some issues that I've put upstream (Mostly for nova):

These are incorporated in the patches I have for the repositories.

Discussion points

Variable locations/precendence

Currently using testing defaults as an include within the play files - this lives inside the generic repository (this one) Using a {rolename}-overrides.yml within each role's repository we can set various vars that are non-default (these are pretty minimal though for the roles I've done. nova/glance/keystone/swift). Open to suggestions/discussion.

Rolename includes

To use a generic keystone playbook for testing (as an example), we need to set the rolename to be a default of os_keystone (this is how we specify it in ansible-role-requirements). However for keystone testing we need it to be openstack-ansible-os_keystone, so there are 2 options:

  1. We set the the ansible-role-requirements to clone ALL repos to openstack-ansible-x and code the rolenames as such.
  2. We have a var per repo to specify its own rolename (e.g. openstack-ansible-os_keystone) and use the shortname as a default.

I've gone with option 2 for the purposes of this PoC Open to other suggestions/discussion.

Inventory management

For swift I have split out the group/host_vars so that very little is in the inventory, I think this is the way forward. This isn't generic to roles - so isn't really covered in this, but I'd like a uniform method of preparing hosts.

Method of running plays

There was an idea to simply run the test.yml from the generic repo which will call all the appropriate repos. This will fail if the requirements repositories don't exist though, regardless of whether they are used. For example, rabbitmq isn't used by swift, but you would need to download the role just to be able to ignore the rabbitmq role. I've gone with the alternative, for the purposes of this PoC, which is to specify in the role repositories, which generic playbooks to run.

I think the decisions made so far are solid but feel free to give ideas/discuss etc. Here are the 4 repositories I have working with this method, so you can see the patch required to get it working on each repository:
