How can I add multiple tags for the same image?

[jdkent]

I'm treating this as a list, this is not the correct syntax:

name: Build and push
        uses: docker/bake-action@v2
        with:
          files: docker-compose.yml
          push: true
          load: false
          pull: false
          set: |
              worker.tags=["ghcr.io/${{ env.OWNER_LC }}/neurovault:${{ hashFiles('**/neurovault/**') }}", "ghcr.io/${{ env.OWNER_LC }}/neurovault:${{ env.SANITIZED_BRANCH_NAME }}"]
              worker.cache-from=type=registry,ref=ghcr.io/${{ env.OWNER_LC }}/neurovault:${{ hashFiles('**/neurovault/**') }}
              worker.cache-from=type=gha,scope=cached-neurovault
              worker.cache-to=type=gha,scope=cached-neurovault,mode=max
              django.tags=["ghcr.io/${{ env.OWNER_LC }}/neurovault_fs:${{ hashFiles('**/neurovault/**') }}", "ghcr.io/${{ env.OWNER_LC }}/neurovault_fs:${{ env.SANITIZED_BRANCH_NAME }}"]
              django.cache-from=type=registry,ref=ghcr.io/${{ env.OWNER_LC }}/neurovault_fs:${{ hashFiles('**/neurovault/**') }}
              django.cache-from=type=gha,scope=cached-neurovault_fs
              django.cache-to=type=gha,scope=cached-neurovault_fs,mode=max

Does anyone know the correct syntax for specifying multiple tags?

Thank you!

        uses: docker/bake-action@v6
        with:
          .....
          set: |
            *.tags=registry/image_name:latest
            *.tags+=registry/image_name:othertag

Try something like that to add more than one tag to the images. You may need to replace the * with your image name.

Yes you can append with += operator: https://docs.docker.com/reference/cli/docker/buildx/bake/#set

How does that work when I have multiple services in a docker-compose file? I would like to append tags to all of them without specifying every single service like registry/image_name:mynewtag?
