Description

I have a bake configuration that uses matrix:

target "foo1" {
  matrix {
    VAR = ["a", "b", "c"]
  }
}

target "foo2" {
}

Expected behaviour

Build summary includes foo1 images

Actual behaviour

Build summary only includes foo2 image

I see it exports two refs here and I guess it should be three.

Can you show the docker/bake-action@v6 logs please? Would like to see the Bake definition output like https://github.com/docker/bake-action/actions/runs/13028830780/job/36343369617#step:6:213

And also the Metadata https://github.com/docker/bake-action/actions/runs/13028830780/job/36343369617#step:6:306 and Build references https://github.com/docker/bake-action/actions/runs/13028830780/job/36343369617#step:6:387

Thanks

The whole log is full of lines that would need scrubbing but it's only just our own build output. Example lines for matrix images are like

#159 [foo1-a] exporting to image
#159 pushing layers 3.8s done
#159 ...

And also the Metadata https://github.com/docker/bake-action/actions/runs/13028830780/job/36343369617#step:6:306 and Build references https://github.com/docker/bake-action/actions/runs/13028830780/job/36343369617#step:6:387

Metadata is probably relevant. It has much more output for foo2 than foo1. foo1 entries are output like:

    "foo1-a": {
      "containerimage.digest": "sha256:fd0a44ef71590ffd6a24d965f0bf76d8b4cbf0fab7f77beeff75317dbcf03278"
    },
    "foo1-b": {
      "containerimage.digest": "sha256:da1731a3b50ddda9fd50ad84ee6a3602349e39c8107b7d8ae1a64b634c57d106"
    },

Build references:

  builder-<UUID1>/builder-<UUID1>/<ID1>
  builder-<UUID1>/builder-<UUID1>/<ID2>
  builder-<UUID1>/builder-<UUID1>/<ID3>

Latest release v6.17.0 should fix this issue. It now exports using the buildx history export command instead of the legacy export-build tool.
