Unfortunately, this is the current limitation of Docker. There is no way to use a Dockerfile not from context when building an image for a compressed context that reads from STDIN (default werf behavior).

There are no such limitations when using the Buildah backend, and we can add such a possibility. I'll make sure to keep you informed.
