Follow-up PR

When terraform apply fails in tfaction, you need to resolve the failure. tfaction downloads the plan file from GitHub Artifacts and runs terraform apply. Once terraform apply fails, the plan file becomes stale, and rerunning the failed workflow run will fail again. Therefore, you need to create a new PR.

info

If the workflow fails due to a transient error before terraform apply runs, rerunning the workflow may resolve the issue.

tfaction can automate the creation of this PR. This automatically created PR is called a "follow-up PR." Add the create-follow-up-pr action after the apply action:

- name: Apply
  uses: suzuki-shunsuke/tfaction@latest
  with:
    action: apply
    github_token: ${{ steps.token.outputs.token }}

# Add this after apply
- name: Create follow up PR
  uses: suzuki-shunsuke/tfaction@latest
  if: failure()
  with:
    action: create-follow-up-pr
    github_token: ${{ steps.token.outputs.token }}

Review the apply error message and the plan result of the follow-up PR to fix the problem. If the follow-up PR's plan result is "No Change", it is most likely safe to simply close the follow-up PR without any action.
