  • This adds an 'escape hatch', allowing the repo user to pass in additional arguments to
    repo2docker that we may not explicitly have options for.
  • Adds another option to force a specific version of repo2docker to be installed. Potentially
    helpful for reproducibiliy, but also helpful when we want to test an unreleased version of
    repo2docker
  • Install some base python packages required to build repo2docker from source - this is
    required if we want to install an unreleased version of repo2docker. This mostly brings in
    packages present in the build stage of the upstream repo2docker image that we use:
    https://github.com/jupyterhub/repo2docker/blob/main/Dockerfile

You can see an example of this in action in volcanocyber/VICTOR-notebook#6,
where we switch the base image to Ubuntu 22.04 by bringing in this PR: jupyterhub/repo2docker#909

Do we want this to be a required flag?
Update: this looks like it isn't actually used, so it could be removed?

I figure "in the image" is confusing as "the image" could be the GitHub action container image or the built repo2docker image. So I suggest "in the environment where repo2docker is run" instead.

But also since I suggested removing FORCE_REPO2DOCKER_VERSION in favor of sticking with EXTRA_PIP_INSTALL I figure we also need a note about using this to pin repo2docker's version.

And finally, this includes @GeorgianaElena require: false addition.

description: Extra packages to install in the environment that runs repo2docker. You can for example use this to pin a specific version of repo2docker by providing `repo2docker==<version>` or `git+https://<github-url>@<commit-hash` to reference a repo2docker fork not on PyPI.

There are lengthy notes as it took a while for me to think this through, but I think I got this reduced to quite clear suggested changes making these review notes more of a background to my suggested changes.

Review notes

I figure ideally this should be three PRs as this adds three separate things, currently the title reflects only Add REPO2DOCKER_EXTRA_ARGS input I think. I care to a large extent because I want the changelog to be easy to follow from the changelog titles.

  • REPO2DOCKER_EXTRA_ARGS
    The implementation of this is straight forward and seems ok, I can go for a quick merge on a PR adding this especially since a changelog entry is self explanatory with a title focused on adding that.
  • FORCE_REPO2DOCKER_VERSION
    • I added an inline comment about why we added base-build python3-dev at all time to the custom Dockerfile we have.
  • EXTRA_PIP_INSTALL
    • This is an input added to the action.yml but not implemented in any way. I suspect its a remnant after needing python3-dev to be able to build repo2docker.

Discussion points

Regarding FORCE_REPO2DOCKER_VERSION

  • Naming:
    • I think the FORCE_ prefix is more verbose than we need to be
    • I suspect _VERSION is a surprise as it really is a pip install entry of some kind.
  • Implementation:
    • I suspect adding build-base and python3-dev setup time will increase quite notably even if this feature isn't used and don't feel great about it, what could be done? Depends, keep reading...
    • If a GitHub Dockerfile based action that first builds an action and then runs it can be adjusted already while it builds the Dockerfile, then maybe we can make this be conditionally installed. I think though you can't. The documentation don't mention it and the Job's start out by preparing Dockerfile actions by building the Dockerfile, and when they do, no information is passed with build-args etc.

With all of this considered...

Suggested changes

  1. Let REPO2DOCKER_EXTRA_ARGS be a dedicated PR very easy to merge quickly and include the name in the title
  2. Transform this PR to a EXTRA_PIP_INSTALL + base-build and python3-dev PR where FORCE_REPO2DOCKER_VERSION is dropped. Let the PR title reflect that EXTRA_PIP_INSTALL is added. Document the input with a note that EXTRA_PIP_INSTALL can be used to install a specific repo2docker version.
