Question

Your team maintains a 'CI' workflow that runs on every push. You want a separate 'Deploy' workflow to run automatically only after the 'CI' workflow finishes successfully on the main branch, and you must inspect whether that upstream run passed before deploying. Which trigger and condition configuration achieves this?

Accepted Answer

Use `on: workflow_run` with `workflows: ["CI"]` and `types: [completed]`, then gate the deploy job with `if: github.event.workflow_run.conclusion == 'success' && github.event.workflow_run.head_branch == 'main'`

Answer

Use `on: workflow_call` in the Deploy workflow so the CI workflow can invoke it, and check `if: success()` at the job level

Answer

Use `on: push` in the Deploy workflow with `needs: CI` to establish a dependency on the CI workflow

Answer

Use `on: workflow_run` with `types: [requested]` and gate with `if: github.event.workflow_run.status == 'completed'`
