Module 6 · Recall check

1. A pod is stuck in `ImagePullBackOff`. Which command is the single most useful first move?

2. A container has exit code 137 after being terminated. What does that tell you?

3. A pod is `Running` but the Service in front of it never gets traffic. Its restart count is 0 and logs look healthy. What's the most likely cause?

4. You're debugging a crashing pod whose image is `gcr.io/distroless/static:nonroot` — no shell, no tools. What's the cleanest way to poke around inside?

5. A pod is `Pending` on a brand-new namespace. `describe pod` shows `Events: 0/3 nodes are available: 3 Insufficient memory.` You have two pending pods in the same state. What are the non-destructive options?
