seeing the same problem

hanging on "resolve image config for docker-image://docker.io/docker/dockerfile:1"

Yes, similar issue... this is the specific build step I'm hanging on for Docker Hub: load metadata for docker.io/library/node:22-bookworm-slim

Hmm,
Are any of y'all able to consistently reproduce this? Would love to look into getting live logs on whats stuck

Latest deploy effort did build successfully.

However, prior to that I had several timeouts during frontend service build specifically at the docker hub call. Here's the plain text log:

Ah unfortunately that looks like an issue we're actively working on with metal builder.
Have a project ongoing that should resolve and speed up multiple parts of the "push code" -> "get it live" flow.

For now, as a short term fix you can simply disable "use metal builder".

Sorry you ran into this!
