Is there any work planned for dynamic inventory (
https://docs.ansible.com/ansible/2.5/dev_guide/developing_inventory.html) ?
Peers, bricks and volumes are all good candidates for dynamic inventory.

I recommend running ansible-lint in CI. For example:
[ykaul at ykaul gluster-ansible-infra]$ find . -name "*.yml" |xargs
ansible-lint
Syntax Error while loading YAML.
  did not find expected ',' or '}'

The error appears to have been in
'/home/ykaul/github/gluster-ansible-infra/examples/backend_with_vdo.yml':
line 22, column 8, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

       - {vgname: 'vg_sdb', thinpoolname: 'foo_thinpool', thinpoolsize:
'100G', poolmetadatasize: '16G'
       - {vgname: 'vg_sdc', thinpoolname: 'bar_thinpool', thinpoolsize:
'500G', poolmetadatasize: '16G'
       ^ here
This one looks easy to fix.  It seems that there is a value started
with a quote, and the YAML parser is expecting to see the line ended
with the same kind of quote.  For instance:

    when: "ok" in result.stdout

Could be written as:

   when: '"ok" in result.stdout'

Or equivalently:

   when: "'ok' in result.stdout"
