shard

Manifest: shard/action.yml

This action produces a list of versions for an image. This is to be used as a matrix dimension to parallelize builds. It does the following work:

  1. Reads the <IMAGE_NAME>/boil-config.toml file, extracting the versions for the image
  2. Write the JSON array of versions to $GITHUB_OUTPUT for use in a matrix.

Example usage:

jobs:
  generate_matrix:
    name: Generate Version List
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout
      - id: shard
        uses: stackabletech/actions/shard
        with:
          image-name: ${{ env.IMAGE_NAME }}
    outputs:
      versions: ${{ steps.shard.outputs.versions }}

  actual_matrix:
    needs: [generate_matrix]
    strategy:
      matrix:
        versions: ${{ fromJson(needs.generate_matrix.outputs.versions) }}
    # ...
