Description
setting labels with bake fails with "labels require name"
Expected behaviour
docker buildx bake --set=*.labels=x.y=name
should give me an error message or link to a doc on how to specify labels correctly
Actual behaviour
This works:
docker buildx build --label=x.y=name .
This fails:
docker buildx bake --set=*.labels=x.y=name
ERROR: labels require name
i wasn't able to find any examples in the docs about how to set a label from the cli
i eventually figured out that the right syntax is
docker buildx bake --set=*.labels.x.y=name
