Hm, that’s interesting. Are you saying just specifying the FROM in the Dockerfile is enough? I’ve seen a trick floating around specifying from in the bake config in addition to Dockerfile.
You can create contexts that point to other targets. So in your Dockerfile you can use `FROM project-base` where `project-base` is whatever you specified in the context.
