Publish to github registry

[chenrui333]

Right now, you have to build the container every time, it would be nice to publish this into github registry or some other docker registry.

Github Actions have become GA and the minutes for private repositories have become chargeable. This will help save some minutes.

I understand the need for this, but unfortunately this feature does not seem to be ready yet, see this forum thread: https://github.community/t5/GitHub-Actions/docker-pull-from-public-GitHub-Package-Registry-fail-with-quot/td-p/32782

However, I have pushed v0.6.0 to docker.pkg.github.com now, so when GH enables the feature, you should be able to switch to using the pre-built Docker image immediately.

For security reasons, I recommend to use the full SHA, when referencing the Docker image (as I also recommend when referencing the action from GH directly). So the workflow file should look like this:

# [...]
jobs:
  automerge:
    runs-on: ubuntu-latest
    steps:
      - name: automerge
        uses: "docker://docker.pkg.github.com/pascalgn/automerge-action/automerge-action:c7859ab63774304798c4dd36ed106b59bbf728974117a9f350cac756d80d9e37"
        # [...]

(the usual Docker syntax would be docker.pkg.github.com/pascalgn/automerge-action/automerge-action@sha256:c7859ab63774304798c4dd36ed106b59bbf728974117a9f350cac756d80d9e37, but for some reason GH chose to use a slightly different syntax here)

Also, I pushed that image manually, but when someone finds a good example where the action is automatically built and pushed to docker.pkg.github.com, feel free to link it here!

I will leave this issue open until GH fully supports pulling from docker.pkg.github.com in actions.

Just had a dig into this as running hundreds of this action a day is eating into our Actions minutes, and Microsoft still has not fixed this issue :(

Thanks for leaving this open though, hopefully we'll see a fix one day

Not sure I understand how this action differs from others I use, but I get An action could not be found at the URI 'https://api.github.com/repos/pascalgn/automerge-action/tarball/0.8.4' if I use uses: "pascalgn/[email protected]" is that caused by this issue? It's probably worth calling out in the readme because it seems to be unique to this action.

[pascalgn]

I think it's not related to this issue, it could be because you use 0.8.4 instead of v0.8.4. If it's fine for you, I would like to ask you to create a new issue for that topic, if you have additional questions/remarks.

[jrjohnson]

Yup, that was the issue. Sorry for the noise! 😊

Hi, have you considered publishing the docker image to DockerHub until GitHub solves (if ever) the authentication issue with their own registry?

I'm referring to this answer in the community thread: https://github.community/t/docker-pull-from-public-github-package-registry-fail-with-no-basic-auth-credentials-error/16358/37

PS. I'm not a Docker 🧙 , therefore, I'm not sure if it'll work but I'm willing to help with reducing GH Action minutes usage in this case.

@pascalgn Could this allow us to cache the Docker image here?

[pascalgn]

The action is now a JS action and no longer uses Docker now (see #125 and #135) so I will close this 😊
