> to run CI in a container specified by the repo

Would you happen to have an example YAML at hand?

Here's one:

https://github.com/ahepp/resume/blob/d7778b1339271cbd7812634...

It uses GitHub's devcontainer plugin. There's a devcontainer config at .devcontainer/devcontainer.json, which says to use the image specified by .ci/Dockerfile.

So when I'm developing on any Linux system, I can run

    $ docker build .ci/Dockerfile -t my-container
    $ docker run --rm -it -v $(pwd):/project -w /project my-container

And have a shell with my LaTeX environment all ready to go.

I can also create a GitHub codespace from the devcontainer config. I'm excited to explore more of the possibilities with devcontainers. I've included Dockerfiles with all my projects for quite a while now, it's cool to have some kind of standard written down that tooling can be written for.

I think the GitHub YAML a slight improvement over the old Jenkins configs it replaced:

https://github.com/ahepp/resume/commit/a144ee06b868ae867b287...

For one, there's no out-of-band Jenkins UI I need to configure the pipeline in. The syntax is probably a slight improvement over Jenkins. I'm also happy to use opaque plugins for certain things, like uploading to S3.

Thank you for sharing! This shows nicely how you can keep the GitHub YAML at minimum by referring to an action (in this case devcontainers/ci) which configures itself based on the content of the repo.
