Answer
Due to insufficient resources, PVC issues, taints, or affinity mismatch.
Quick Answer
Pods stay Pending when: no node has enough resources (insufficient CPU/memory), no node matches Pod's nodeSelector or affinity rules, all matching nodes have taints the Pod doesn't tolerate, PVCs can't be bound (no matching PV), or an image pull limit is blocking. Describe the Pod (kubectl describe pod) to see which scheduler condition is failing.
