Summary

  • Default REGISTRY_URL to docker.io and rename the image to positro/openpi-base (was Nebius cr.eu-north1.nebius.cloud/.../openpi-training)
  • This makes make push publish exactly the base image the positronic docker/Makefile pulls via --build-arg BASE_IMAGE=positro/openpi-base:latest; previously the two never connected (different registry and name)
  • Pin the build to --platform linux/amd64 so builds on Apple Silicon still produce amd64 images, matching the positronic Makefile convention
  • REGISTRY_URL remains overridable for the old Nebius target

Test plan

  • make -C docker help shows Registry URL: docker.io and image positro/openpi-base
  • Pushing requires docker login with push access to the positro Docker Hub namespace (manual; no CI publishes this image)

…md64

Default REGISTRY_URL to docker.io and rename image to positro/openpi-base so it matches the base image the positronic Makefile pulls. Pin the build to linux/amd64.
