setup-buildx-action VS exec

Is it this? https://github.com/docker/setup-buildx-action/issues/358

Good luck running this locally. There's no script code to speak of, just references to external "actions" and parameters (for example, https://github.com/docker/setup-buildx-action).

Some CI platforms are just a simple glue layer (Gitlab CI - which I prefer - is one of them), but in most cases Github CI is not. Maybe it adds to the author frustration?

Set up Docker Buildx: We will use the docker/setup-buildx-action action to set up Docker Buildx.

There’s an amazing docker/bake-action which makes it insanely easy to build all of your containers in the most optimal way. Since we’ve set the group “default” block in the docker-bake.hcl, config is very minimal. One step in your GitHub Action workflow file will build all of your images and will push all of your cache layers, tag all of your containers, and push all your final images. You’ll still have to do things like checkout the code and don’t forget that you’ll want to use the docker/setup-buildx-action since bake is a buildx feature. There’s one quick gotcha for the actual docker/bake-action. We don’t want to push PR builds and we don’t want to pollute the cache with PR builds.

To be clear, that article does NOT provide a solution for avoiding QEMU. I suggested it because it describes "the hard way" to get a single image multi-arch image. The github action crazy-max/ghaction-docker-buildx has been archived and replaced by docker/setup-qemu-action and docker/setup-buildx-action, which it seems like you were already using.

Third step is docker/setup-buildx-action configures buildx, which is a Docker CLI plugin that provides enhanced build capabilities.

We then use the docker/setup-buildx-action action to initialize an environment to build Docker images:

The setup-buildx-action configures Docker Buildx to create a builder instance for running the image build. The following step build-push-action, makes use of that instance to build your Docker image. The build-push-action supports all of the features provided by BuildKit out of the box. In our simple example, we are only specifying the Docker context, but more advanced features like SSH, secrets, and build args are supported.

@semantic-release/exec - used to set GitHub action environment variables when run as from docker container and GitHub action outputs when run as a marketplace action

This meant that forcing a major tag update with @semantic-release/exec as part of the release process was possible, but would result in the major tag (for example v3) linking to a valid repository commit SHA that is not actually released in the marketplace.

This article introduces semantic-release as a solution. It automates the release process, and its exec plugin helps us to run @vercel/ncc before the release automatically.

You may need a minor tweak up. For example, push some pkg to both public and internal registries. Ooops. "...publishing to two different registry is not a good idea". In this case you can not rely on stable, convenient and tested in millions runs semrel/npm plugin, and you have to just write a pair of commands by hand with semantic-release/exec instead:
