Kubernetes Operations Guide

When to Use This Skill

Use when managing Kubernetes deployments, troubleshooting pod issues, viewing application logs, scaling services, or debugging container problems.

Common Operations

View Resources

kubectl get pods -n <namespace>
kubectl get pods -n <namespace> -o wide
kubectl get pods -n <namespace> -l app=<app-name>
kubectl get deployments -n <namespace>
kubectl get svc -n <namespace>
kubectl get ingress -n <namespace>
kubectl get all -n <namespace>

Logs

kubectl logs -n <namespace> <pod-name>
kubectl logs -n <namespace> <pod-name> -f
kubectl logs -n <namespace> <pod-name> --tail=100
kubectl logs -n <namespace> <pod-name> --previous
kubectl logs -n <namespace> -l app=<app-name> --all-containers=true
kubectl logs -n <namespace> <pod-name> --since=1h

Describe & Debug

kubectl describe pod -n <namespace> <pod-name>
kubectl describe deployment -n <namespace> <deployment>
kubectl get events -n <namespace> --sort-by='.lastTimestamp'
kubectl top pods -n <namespace>
kubectl top nodes

Execute Commands

kubectl exec -it -n <namespace> <pod-name> -- /bin/sh
kubectl exec -n <namespace> <pod-name> -- cat /app/config.json
kubectl port-forward -n <namespace> svc/<service> <local-port>:<remote-port>

Scaling

kubectl scale deployment -n <namespace> <deployment> --replicas=<n>
kubectl get hpa -n <namespace>
kubectl describe hpa -n <namespace> <hpa-name>

Rollouts

kubectl rollout restart deployment -n <namespace> <deployment>
kubectl rollout status deployment -n <namespace> <deployment>
kubectl rollout history deployment -n <namespace> <deployment>
kubectl rollout undo deployment -n <namespace> <deployment>

Troubleshooting

Pod in CrashLoopBackOff

Check logs from previous container: kubectl logs -n <ns> <pod> --previous
Check events: kubectl describe pod -n <ns> <pod>
Common causes: missing env vars, secret not synced, DB connection failed, OOMKilled

Pod in Pending

Check events: kubectl describe pod -n <ns> <pod>
Check node resources: kubectl top nodes
Common causes: insufficient CPU/memory, node selector mismatch, PVC not bound

Pod in ImagePullBackOff

Verify image exists: kubectl describe pod -n <ns> <pod> | grep -A5 "Image:"
Check registry authentication

Service Not Responding

Verify pods are running: kubectl get pods -n <ns> -l app=<app>
Check endpoints: kubectl get endpoints -n <ns> <service>
Test connectivity: kubectl run debug --rm -it --image=busybox -- wget -qO- http://<svc>.<ns>.svc.cluster.local

Best Practices

Always verify context before running commands
Use labels for filtering resources
Check events first when troubleshooting
Don't delete pods without understanding the impact
Use rollout restart instead of deleting pods
Scale gradually — don't jump from 2 to 20 replicas
