"Dynamic" groups

[qraynaud]

My issue

I have a git repos containing all my personal server's applications described using the docker-compose syntax. I’d like to add each application backup config alongside those. So I made my profiles.yaml look like that:

version: 2

global:
  initialize: true
  scheduler: crontab:-:/resticprofile/crontab

groups:
  daily:
    schedules:
      backup:
        at: '03:00'
        permission: user
  # ...

includes:
  - "/config/applications/*/*.backup.yaml"

And I’d like to be able to add to the daily group the profiles of apps that would make sense. Something like:

profiles:
  my-app:
    # ...

groups:
  daily:
    profiles:
      - my-app

Obviously, this does not work because each app file replaces the profiles (like described in the documentation).

Idea 1

Would it be possible to also support the append/prepend syntax in includes:

profiles:
  my-app:
    # ...

groups:
  daily:
    profiles...: my-app

Idea 2

Or to add a groups attribute in profiles that could be used in conjunction with groups.profiles to allow the link to be created wherever it makes more sense?

profiles:
  my-app:
    # ...
    groups:
      - daily

Idea 3

Or maybe it could be both #1 and #2?

Ending word

Great project! Thanks a lot for the hard work!
