Set requests and limits that reflect real usage
Diagnose CrashLoopBackOff and OOMKilled pods

Requests drive scheduling, limits drive eviction. CrashLoopBackOff and OOMKilled are usually a limits conversation, not a code one.

What this lesson covers

Set requests and limits that reflect real usage
Diagnose CrashLoopBackOff and OOMKilled pods
Debug a pod with logs, describe, and exec

This lesson sits in Operating a Cluster, part of DevOps with Docker and Kubernetes. It assumes what came before it and leads directly into the next lesson in the module.

PRO TIP

Requests decide where a pod is scheduled; limits decide when it gets killed. They are not the same number.
