Restore the broken deploy

go-api has been deployed with a nonexistent image tag — pods are stuck in ImagePullBackOff. Your job: identify the problem, update the deployment to a valid image, and get the rollout healthy before the clock runs out.

How it is scored

  • Par time is 10m. Beating it scores higher; the clock starts when you do.
  • Each hint costs 5 points. Taking one is often still the right call.
  • Grading is a real check against the live cluster, so a fix that only looks right scores nothing.

What gets set up
