You want to find out why the pod is stuck in pending status. What should you do?

Explanation

To debug a pod stuck in PENDING status, review the pod's detailed information using 'kubectl describe pod' and check for warning messages about scheduling constraints (insufficient resources, node selectors, etc.). The pod's events display scheduler messages explaining why it cannot be scheduled, which is more diagnostic than viewing deployment status, service details, or container logs (a PENDING pod has not been deployed to a node, so logs are unavailable).
