Add both version tag and branch name tag

I have the following configuration:

            type=raw,value={{branch}}
            type=sha
            type=semver,pattern={{version}}

But when I push just a tag to the main branch, the container is tagged only with latest, 1.0.0 and sha tags, but not with the branch name.

Is it possible to always have a branch name tag in addition to version tag? The goal is to be able to refer either to a specific version tag or the latest container build in each branch.

Ok, it worked after I added a couple of tweaks.

1. This snippet I found on the internet was immensely helpful in debugging the variables:

      - name: Dump GitHub context
        env:
          GITHUB_CONTEXT: ${{ toJson(github) }}
        run: echo "$GITHUB_CONTEXT"

1. The solution that works both for tag pushes and branch pushes looks like this (although it needs more testing)

      - name: Base ref
        run: |
          if [ "${{ github.ref_type }}" = "tag" ]; then BASEREF="${{ github.event.base_ref }}"; BASEREF="${BASEREF#refs/heads/}"; elif [ "${{ github.ref_type }}" = "branch" ]; then BASEREF="${{ github.ref_name }}"; else BASEREF=""; fi
          echo "BASEREF=${BASEREF}" >> $GITHUB_ENV

Thanks a lot! I’ll test the workaround in a couple of days.

And yes, a global expression would be nice: https://github.com/docker/metadata-action/issues/102#issuecomment-859083282
