Allow glob in include statement paths

[brad2014]

Description

To create a compose environment that allows for plugins/extensions, we would like to be able to say:

services:
  # common services for this designed environment

include: docker-compose.d/*.yml # admin selected plugins for this environment, loaded in alphabetical order 

Of course, because the order of inclusion may matter for certain compose environments (not all), the glob would be sorted, and admins would have the ability to name their drop-in files as is customary in traditional unix subsystems that support drop-ins (e.g. /etc/sysctl.d, /etc/grub.d, /etc/X11/xinit/xinitrc.d, etc) : 00-firstcompose.yml, 05-earlycompose.yml, 99-finalcompose.yml, etc.

docker compose -f doesn't support glob patterns, so I don't see any reason include would.

Indeed, the feature request is for a feature that is not currently supported. The use case providing the reason for including it is described in the feature request, to allow for the creation of environments that permit plugins/extensions developed separately and dropped in at the option of the site admin.

Presumably, if this is considered a feature worth supporting, the -f flag could work similarly if the feature were implemented (although that is not part of this feature request, it wouldn't interfere with our use case).

If a decision was already made to consider and reject that use case, my apologies.

Hi, @brad2014.

I also wanted to be able to pass -f *.compose.yaml to merge multiple compose globbed config files together, so I ended up with a bash script to loop over matching files (per the glob) to expand an array of -f $file items as arguments to docker compose and also forward all other args ($@) to the docker compose command. -- Hope this helps!

#!/usr/bin/env bash

files=()
for file in *.compose.yaml; do
	files+=("-f" "$file")
done

docker compose ${files[@]} $@
