======================================
Add support for multiple globals files
======================================
https://blueprints.launchpad.net/kolla-ansible/+spec/multiple-globals-files
Adding this feature to the kolla-ansible script, which will make it, automatically,
read multiple globals files. This would give operators the ability to have
separate globals files for some services, giving them a bit more granular control,
without the need to add the ``-e @/path/to/file`` flag. These files will be placed
under a new ``/etc/kolla/globals.d`` directory and ``kolla-ansible`` will search
for ``globals.d/*.yml`` files. The main ``globals.yml`` file will still exist
under ``/etc/kolla``, as usual.
Problem description
===================
There's no problem, per say, to solve. This feature will basically give operators
the ability to have separate globals files for some services, giving them a bit
more granular control, without the need to add the ``-e @/path/to/file`` flag.
Use cases
---------
1. Allow a more granular controller over individual service's options
2. Better file and directory structure
Proposed change
===============
- Add the capability in the ``tools/kolla-ansible`` script
- Check if the ``globals.d`` directory exists
- If it is, add its files in the ``CONFIG_OPTS`` variable at the end of the ``tools/kolla-ansible`` script
Security impact
---------------
None
Performance Impact
------------------
None
Implementation
==============
Assignee(s)
-----------
Konstantinos Mouzaitis <kon.mouzakitis@vscaler.com>
Milestones
----------
Target Milestone for completion:
ussuri-10.0.0
Work Items
----------
- Add the capability in the ``tools/kolla-ansible`` script
- Check if the ``globals.d`` directory exists
- If it is, add its files in the ``CONFIG_OPTS`` variable at the end of the ``tools/kolla-ansible`` script
Testing
=======
Test the new kolla-ansible script when the ``globals.d`` directory exists and
includes some more yml files, as well as when it doesn't exist.
Documentation Impact
====================
``doc/source/user/quickstart.rst`` will need to be updated to include the options discussed in this feature
