Why Is My Kubernetes Job Still Pending? Tracing Kueue Admission with Headlamp

You submit a Kubernetes Job and wait for its Pods to appear. A minute passes. Then another. The Job is still suspended, there are no application logs, and there may not even be a Pod to inspect. In a cluster managed by Kueue, this can be completely normal. Kueue may still be deciding whether the Job can use the requested resources.
