Description

When using a raw tag with the enable flag, the tag is still in the metadata output when enable is set to false.

Expected behaviour

Run docker/metadata-action@v5

type=raw,value=latest,enable=${{ inputs.is-latest }}

Do you repro as well with type=raw,value=latest,enable=false? If not then that might be related to how GitHub handles boolean inputs.

Yea that question is in the comment of the line where the bug originates from. It is a GHA typed boolean for sure. The peculiar thing is the fix I ended up going with.

Intsead of

- name: Docker Meta
  id: meta
  uses: docker/metadata-action@v5
  with:
    images: ${{ needs.set-workflow-vars.outputs.image-name }}
    tags: |
      type=semver,pattern={{raw}},value=${{ needs.set-workflow-vars.outputs.version }}
      type=raw,value=latest,enable=${{ inputs.is-latest }} # This input is typed as a boolean in the callable workflow, maybe that's it?

I ended up using the flavor input. Which is documented the same as tags as far as booleans go:

- name: Docker Meta
   id: meta
   uses: docker/metadata-action@v5
   with:
     images: ${{ steps.set-vars.outputs.image-name }}
     flavor: |
       latest=${{ inputs.is-latest }}
     tags: |
       type=semver,pattern={{raw}},value=${{ inputs.version }}
