Config for different Dockerfile for release doesnt work

[matramos]

In my config, I add the path for my release just like in
https://github.com/Recruitee/mix_docker#how-to-move-the-dockerfiles

config :mix_docker,
  image: "path/to/image",
  tag: "{app}_{mix-version}_{git-sha}",
  dockerfile_release: "release/Dockerfile.release"

And when I try to do mix docker.release it just run the default Dockerfile.release not the costume written by me.

I tried differents ways to write the path, like ./path, /path, etc. Different names for the Dockerfile and it still doesn't work.

Any ideas?

@matramos I advise migrating to docker multi-stage according to the new readme - https://github.com/Recruitee/mix_docker/pull/58/files
