build-singularity-cvmfs-action

GitHub Action Package for Requesting Singularity Builds on CVMFS

Overview

A CI workflow can request to add or remove Docker-based Singularity builds on CVMFS at a specified directory/sub-directory.

Examples

Minimal Example

These inputs are required.

- uses: WIPACrepo/build-singularity-cvmfs-action@v##
  with:
    github_token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}  # so job can git push
    docker_tags: ${{ needs.docker.outputs.tags }}  # or similar

Full Example

See Skymap Scanner's publish.yml

Under The Hood

This action adds one or more lines to the end of WIPACrepo/cvmfs-actions/docker_tags.txt, and the changes are pushed using the github-actions user (bot). This triggers Singularity-image building and hosting on CVMFS. Optionally, a - prefix is attached to lines when images are requested to be removed.

For example, a line may look like, docker://icecube/skymap_scanner:3 realtime/skymap_scanner:3 for the image tag, icecube/skymap_scanner:3 (See full example). All previous occurrences of this line are removed from the .txt file (including those with and without the - (remove) prefix). This process repeats for each image tag.
