Use with `docker compose push`?

[forabi]

Is it possible for this plugin to work with docker compose instead of docker?

My CI pipeline builds and pushes images with compose:

infisical run \
            --domain=<domain> \
            --projectId=<uuid> \
            --env=staging \
            --command="docker compose build && docker compose push"

Short answer is yes, you can build with docker compose build and then push the built image with docker pussh plugin.

Long answer:
docker compose is in fact a Docker CLI plugin:

docker info                                                                                                                                                 Fri 24 Oct 20:18:02 2025

Compose works with the same image storage as Docker. So you can even build an image with docker compose build and then push it to the registry with docker push. The difference is that you need to specify the full image name instead of the service name when using docker push.

Similarly to docker push, you can use docker pussh to upload an image to a remote machine over SSH.

I was actually asking if we can have a command like docker compose pussh so that I don't have to manually specify which images to push

Ah got it! The compose itself doesn't seem to provide a way to implement extensions for it so I guess this should be a standalone CLI plugin/command that would parse the compose file and implement the push logic for it.

I'm actually working on something very similar for uncloud right now.
uc deploy command:

1. Build an image according to the build section in compose.yaml file
2. Tag the image with git sha/time
3. Push the image to remote machines directly using unregistry
4. Deploy services from compose.yaml on remote machines

I believe this logic could be extracted to create a standalone docker CLI plugin (e.g. docker compose-pussh) that would work for compose files. Alternatively, it could be just a tiny script that parses the compose file, extracts the image names from them (assuming they're built with docker compose build) and calls docker-pussh to upload them over ssh.
Although, I won't have time working on this in the near future.
