docker stack deploy use COMPOSE_FILE environment variable

[augnustin]

I recently found about the COMPOSE_FILE environment variable that could be set in .env file (doc).

Is there any plan on integrating this to docker stack deploy, as I find my deploy command ugly and hard to remember (I need to copy/paste it each time).

docker stack deploy --prune -c docker-stack.yml -c docker-compose.yml myapp

Thanks

I'm not sure if the .env file is something that will be supported, but the COMPOSE_FILE variable could perhaps be considered.

With the removal of the experimental .dab file (--bundle-file) option in #2216, perhaps docker stack deploy could now look for a docker-compose.yml by default as well (but that would obviously not solve your example which is using multiple compose files)

Using docker-compose.yml by default would be great too!

In general, I would be in favor of aligning docker stack deploy behavior with docker-compose one:

• default is docker-compose.yml
• extendable by default with docker-compose.override.yml
• can be set with COMPOSE_FILE environment variable

Any plans?
