Any plan on supporting docker-compose

[arnav13081994]

I was wondering if there was any plan to support build images from docker-compose as well?

@arnav13081994 I thought about it and it would need many changes int he code, and as you can accomplish the same creating a step for each image you need to build based on the compose file, I decided it wasn't worth it.

I am not telling I can't change my mind in the future. I will leave this open just in case I have some free time to give it a try and to see if there are more people interested.

@whoan Yes, you are right.

@whoan That sounds like a good option that would probably save a lot of headaches. Do you know if I build the images using this action separately, will this cache be used by docker compose afterwards?

[whoan]

I tried to think of the different use cases reading from a compose file and having multiple images hosted in different registries is not an easy scenario to handle without many changes in the script.

I still think that it's better to build individually and then the docker-compose build should take advantage of the cache created by the individual builds as long as you use the correct names in the compose file in subsequent steps of the same job (that is what happens if you build individually in your host and then run docker-compose build).

I will continue thinking on it though.

hmm, this Action rocks!
But we have a build script that uses docker-compose to build mutiple images. I used this action to build individual images but it results in:

• Duplication of the config
• passing multiple build args is a bit hard if you have a lot
• You can't build locally the same way as you would in the CI pipeline. Our build script was designed so it would build and behave the same way no matter where it ran.

So the ability to run docker build or docker-compose would be amazing.

I also tried to use this action but it seems to make my builds even slower than if I don't use any cache at all.

I would appreciate if this is given some thought.

Hi @NasAmin . Thanks for your feedback.
I promise I will give another chance to this issue in my spare time and will let you know the outcome.

@NasAmin @arnav13081994 @helloguille You can test the branch support-compose-files to see if it works for you. I made this test and seems to work fine. I will wait for some feedback to merge and release a new version (probably v5.8.0)
