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:
- Move out playbooks for role installs
- Move out variables to become a
test-defaultvars. - 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:
- We set the the
ansible-role-requirementsto clone ALL repos toopenstack-ansible-xand code the rolenames as such. - 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:
