Question

A busy shared namespace hosts many apps. How should an operator list only the 311 application Pods for monitoring?

Accepted Answer

kubectl get pods -l app=311 (or the app’s label selector) to filter to that application. — Labels are name tags in a crowded hallway. Use kubectl get pods -l with the 311 app’s selector and you only see that team’s Pods. Scanning every namespace by eye—or deleting everything—isn’t monitoring.

Answer

kubectl get pods --all-namespaces and mentally filter by image name alone.

Answer

kubectl get nodes -l app=311 and assume node labels equal Pod membership.

Answer

kubectl delete pods --all so only new Pods remain to watch.
