Konstantinos Mouzakitis f6d8c0d481 Adding support for multiple globals files 
Added a spec file for this blueprint.
Changed the kolla-ansible script to accept more than one
globals.yml file. That will still be the main one but operators
will be able to create more, under the /etc/kolla/globals.d
directory.
Also added some paragraphs in the quickstart documentation
about this.
Finally, Adding a release note

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 controler 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

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
