Setting tags not shown in the matrix example

[andy5995]

Is this a docs issue?

• My issue is about the documentation content or website

Type of issue

I can't find what I'm looking for

Description

In the example for the workflow using the matrix, setting the tags isn't shown.

Location

https://docs.docker.com/build/ci/github-actions/multi-platform/

Suggestion

Do the tags only need to be set in the meta section?

I'm trying this:

      -
        name: Docker meta
        id: meta
        uses: docker/metadata-action@v5
        with:
          images: ${{ env.REGISTRY_IMAGE }}
          tags: type=raw,value=dependencies-latest

-
        name: Build and push by digest
        id: build
        uses: docker/build-push-action@v5
        with:
          context: .
          file: ./dependencies.dockerfile
          platforms: ${{ matrix.platform }}
          labels: ${{ steps.meta.outputs.labels }}
          outputs: type=image,name=${{ env.REGISTRY_IMAGE }},push-by-digest=true,name-canonical=true,push=true
          tags: ${{ steps.meta.outputs.tags }}

The build finishes but the push fails:

#15 exporting config sha256:702f28b89befc2ea0d12a904c3a353ccf80cb4be0d9770769b5839c9b997e53b done

Here's a real-world workflow with the implementation. Note the "tags" section is only in the merge job.

Hi!
I'm struggling with the same thing.
If we add tags, we get an error:

Error: buildx failed with: ERROR: invalid tag "xxx/yyy:zzz": invalid reference format
buildx failed with: ERROR: failed to solve: failed to push xxx/yyy:zzz: can't push tagged ref docker.io/xxx/yyy:zzz by digest

If we remove the tags to push-by-digest it fails with:

Error: buildx failed with: ERROR: tag is needed when pushing to registry

I think this is still an issue, following the example at https://docs.docker.com/build/ci/github-actions/multi-platform/#distribute-build-across-multiple-runners I still get the error reported at the top of the ticket
