shard

Manifest: shard/action.yml

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

1. Reads the conf.py, filtering versions for the product
2. Write the JSON array of version 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:
          product-name: ${{ env.PRODUCT_NAME }}
    outputs:
      versions: ${{ steps.shard.outputs.versions }}

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