After mutliple tries, i'm not sure it's improve a lot the build time.

probably because it's concurrent build.

@albttx can you please update the branch to the latest master and resolve conflicts? 🙏

[albttx]

@zivkovicmilos So i fixed / rebased this PR, and added a workflow that didn't push the Docker image (this can be remove if you want).

The idea is to add a simple dockerfile that could be use by dev (because the goreleaser version require the go toolchain locally, this is a more "pure" docker image where the binaries are built inside the images.

This Dockerfile is require for me for the ci/portal-loop test!
