Support `configs:`

[jmaibaum]

Is your feature request related to a problem? Please describe. I tried to run https://git.sr.ht/~emersion/sr.ht-container-compose/ which requires configs: support. However, I always got "No such file or directory" errors being displayed for all defined configs.

Describe the solution you'd like Full support for configs: would be the preferred solution. :smiley:

Describe alternatives you've considered I don't really think there is an alternative to supporting configs, because, if a compose file uses (and thus requires) them, you cannot use podman-compose right now.

Additional context https://docs.docker.com/compose/compose-file/05-services/#configs https://docs.docker.com/compose/compose-file/08-configs/

Minimal example

$ cat compose.yaml 
configs:
  my_config:
    file: ./my_config.ini
services:
  busybox:
    image: busybox:latest
    command: /bin/sh -c "id; ls -lash /; cat /my_config.ini"
    configs:
      - my_config
$ cat my_config.ini

I agree, this is part of the compose-spec, podman-compose really ought to support it!
