PR numbers are easy to come by in PRs, but passing those same numbers to releases, merge queues and PR-backed merges can get tricky. This action makes that convenient in the following cases:

• PR merge queues
• Merged PR workflows
• Release events (finds the most recently merged PR)
• PRs themselves (just for consistency)

This process has been an integral part of PR-based workflows where images are promoted from development (PRs) to test/staging to production. It is also useful for release events where the most recent PR is tied to the release.

The build will return a PR number as output.

- id: vars
  uses: bcgov/[email protected]

- name: Echo PR number
  run: echo "PR: ${{ steps.vars.outputs.pr }}"

Private repositories may need to provide a GitHub token.

- id: vars
  uses: bcgov/[email protected]
  with:
    token: ${{ secrets.GITHUB_TOKEN }}

- name: Echo PR number
  run: echo "PR: ${{ steps.vars.outputs.pr }}"
