Static website, mission 7 of 7
The 3am page
intermediate, about 12 minutes, in the Kubernetes Simulator
Start mission
Opens once you pass Ship v2.
The briefing
You're on call. web is running happily on nginx:1.28… for now. Something is about to change.
When a rollout goes wrong, don't guess. Find which pods are unhappy (kubectl get pods), then ask why: kubectl describe pod NAME ends with the pod's events, and the events usually say exactly what failed.
Two ways out: fix the image and roll forward, or kubectl rollout undo to go back to the last revision that worked.
What you'll do
- Find out why the new pods won't start
- Get web healthy: every pod running on an image that exists
- Bonus star: Fix it with kubectl rollout undo
The mission checks the cluster, not your keystrokes: any fix that works, passes.
