kubectl logs -n

-f kubectl logs -n

--tail=100 kubectl logs -n

--previous kubectl logs -n -l app= --all-containers=true kubectl logs -n

--since=1h ``` ### Describe & Debug ```bash kubectl describe pod -n

kubectl describe deployment -n kubectl get events -n --sort-by='.lastTimestamp' kubectl top pods -n kubectl top nodes ``` ### Execute Commands ```bash kubectl exec -it -n

-- /bin/sh kubectl exec -n

-- cat /app/config.json kubectl port-forward -n svc/

: ``` ### Scaling ```bash kubectl scale deployment -n --replicas= kubectl get hpa -n kubectl describe hpa -n

``` ### Rollouts ```bash kubectl rollout restart deployment -n kubectl rollout status deployment -n kubectl rollout history deployment -n kubectl rollout undo deployment -n ``` ## Troubleshooting ### Pod in CrashLoopBackOff 1. Check logs from previous container: `kubectl logs -n --previous` 2. Check events: `kubectl describe pod -n ` 3. Common causes: missing env vars, secret not synced, DB connection failed, OOMKilled ### Pod in Pending 1. Check events: `kubectl describe pod -n ` 2. Check node resources: `kubectl top nodes` 3. Common causes: insufficient CPU/memory, node selector mismatch, PVC not bound ### Pod in ImagePullBackOff 1. Verify image exists: `kubectl describe pod -n | grep -A5 "Image:"` 2. Check registry authentication ### Service Not Responding 1. Verify pods are running: `kubectl get pods -n -l app=` 2. Check endpoints: `kubectl get endpoints -n ` 3. Test connectivity: `kubectl run debug --rm -it --image=busybox -- wget -qO- http://..svc.cluster.local` ## Best Practices 1. Always verify context before running commands 2. Use labels for filtering resources 3. Check events first when troubleshooting 4. Don't delete pods without understanding the impact 5. Use `rollout restart` instead of deleting pods 6. Scale gradually — don't jump from 2 to 20 replicas --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/arvoreeducacao) — claim your Tome and manage your conversions.
