Question

A user reports that a pod running their Java application repeatedly restarts under load. You run 'kubectl describe pod payment-api-7f9d' and observe the container's Last State shows 'Terminated' with 'Reason: OOMKilled' and 'Exit Code: 137'. The pod spec sets 'resources.limits.memory: 256Mi'. What is the most appropriate first action to resolve the restarts?

Accepted Answer

Increase the container's memory limit (and request) to a value that accommodates the application's actual working set, then redeploy

Answer

Add a liveness probe with a longer initialDelaySeconds so the container is not killed prematurely

Answer

Delete the pod so the ReplicaSet recreates it on a node with more free memory

Answer

Set the pod's restartPolicy to Never so it stops looping
