tomevault-io Kubernetes Operations
Activate this skill when working with Kubernetes clusters and workloads.
When to Use
- Deploying applications to Kubernetes
- Troubleshooting pod failures or scheduling issues
- Configuring networking (services, ingress, network policies)
- Managing secrets and configuration
- Scaling workloads and configuring autoscaling
- Debugging container crashes or connectivity issues
Common Operations
# Check pod status and events
kubectl get pods -n <namespace>
kubectl describe pod <pod-name> -n <namespace>
kubectl logs <pod-name> -n <namespace> --previous
# Debug networking
kubectl exec -it <pod> -- nslookup <service>
kubectl get endpoints <service>
kubectl get networkpolicies
# Resource management
kubectl top pods -n <namespace>
kubectl get hpa
Troubleshooting Flow
- Check pod status (Pending, CrashLoopBackOff, ImagePullBackOff)
- Read events with
kubectl describe - Check logs (current and previous container)
- Verify resource requests vs node capacity
- Check network policies and service endpoints
- Verify secrets and configmaps are mounted correctly
Rules
- Always specify namespace explicitly
- Use labels and selectors consistently
- Set resource requests AND limits on all containers
- Implement liveness, readiness, and startup probes
- Use pod disruption budgets for critical workloads
- Never use
kubectl editin production -- use GitOps - Store manifests in version control
