PR creation while checking out from tag

[Poornachand200]

Subject of the issue:

I am trying to create a pull request from checking out to a tag. I have supplied input base as main. Nevertheless I am facing the error fatal: ref HEAD is not a symbolic ref.

Goal:

I have the required the changes in the tag. peter-evans/create-pull-request@v6 has to create a pull request for the new changes in the existing tag to main branch from the branch "release/${{inputs.product}}-test-to-production" to be created. How to achieve this?

  You are in 'detached HEAD' state. You can look around, make experimental
  changes and commit them, and you can discard any commits you make in this
  state without impacting any branches by switching back to a branch.

  If you want to create a new branch to retain commits you create, you may
  do so (now or later) by using -c with the switch command. Example:

    git switch -c <new-branch-name>

  Or undo this operation with:

    git switch -

  Turn off this advice by setting config variable advice.detachedHead to false_

Hi @Poornachand200

The reason this isn't working is not the message you see in the logs about detached HEAD, it's this line here: Branch 'release/pingfederate-test-to-production' is not ahead of base 'main' and will not be created

Please follow this example: https://github.com/peter-evans/create-pull-request/blob/main/docs/examples.md#keep-a-branch-up-to-date-with-another

My understanding is that you want to update main from the specified tag. So your solution should look something like this:

jobs:
  productionPromotion:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          ref: main
      - name: Reset main branch to match the specified tag
        run: |
          git fetch origin ${{ inputs.tag }}:${{ inputs.tag }}
          git reset --hard ${{ inputs.tag }}
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v6
        with:
          branch: "release/${{inputs.product}}-test-to-production"

I've never tried to use this method with a tag before, so it will be interesting to hear if it works ok.

[Poornachand200]

I tried updating the workflow like this. Attached the screen shot of the pull request and the extracted logs.

The below screen shot in create pull request steps shows only file is modified and will be added. But the created PR has the file which is copied in copy step in below. I need to ignore the file in test folder after copy step. The PR shouldn't have the test folder changes.

      - name: Copy PingDirectory
        if: inputs.product == 'pingdirectory'
        run: |
          rm -rf ./nuuday-ciam/production/pingdirectory
          cp -r nuuday-ciam/test/pingdirectory/ nuuday-ciam/production/pingdirectory
          find ./nuuday-ciam/production/pingdirectory/ -name '*_test.*' -type f -delete

      - name: Copy PingFederate
        if: inputs.product == 'pingfederate'
        run: |
          npm install --dev --prefix .build
          rm -rf nuuday-ciam/production/pingfederate
          cp -r nuuday-ciam/test/pingfederate nuuday-ciam/production/pingfederate
          find ./nuuday-ciam/production/pingfederate/ -name '*.css.map*' -type f -delete
          npm run config:production --prefix .build

add-paths doesn't seem to work as expected. It also add nuuday-ciam/test which doesn't match.
