##Kubernetes Troubleshooting
The most important tool to know for debugging problems is the describe resource command. It can be used to describe any Kubernetes resource.
kubectl describe pod helloworld-service-v1-119527584-jwfzh
kubectl describe service helloworld-service
kubectl top can be used to see resource utilization. A very common problem is the pod was not able to be scheduled.
kubectl top nodes
kubectl top pods
