Kubernetes offers powerful tools, but when things go wrong with your pods, the right commands and log locations can save you a ton of time. Here’s a quick guide to some common issues and how to handle them:
Commands to Check Logs:
For specific pod logs:
kubectl logs pod_name container_name
To exec into the pod's container :
kubectl exec pod_name -c container_name -- /bin/sh
Important Log Locations:
/var/log/kube-apiserver.log
/var/log/kube-kubelet.log
/var/log/kube-controller-manager.log

Common Pod Issues:
Pod Stuck in Pending:
Usually resource-related, like insufficient CPU or memory.
Solution: Scale up resources (increase CPU/memory allocation).
Pod in Waiting State:
This is often due to an incorrect or missing image in the YAML file.
Solution: Ensure the image is correct and available in the mentioned repository.
ImagePullBackOff:
Possible causes: wrong image tag, repo authentication failure, or RBAC issues.
Solution: Verify the image name, tag, and authentication.
CrashLoopBackOff:
Typically caused by resource insufficiency or host port conflicts.
Solution: Check resources and network configurations.
Tip: If you see a CreateContainerConfigError, dig deeper into the pod and container logs to understand the root cause.
