Troubleshooting

1. Describe a pod​

kubectl describe pod backend-service -n application

When to use examples:

  • When a pod is stuck on pending

2. Describe a deployment​

k describe deployment configuration-server

When to use examples:

  • You just ran a helm upgrade, and a deployment was created, but no pods were created.

3. Get Nodes​

kubectl get nodes

When to use examples:

  • node STATUS might SCHEDULE something, which makes new pods get stuck on pending.
  • wanting to check the docker architecture

To enable scheduling on your node:

kubectl uncordon eastus-prod-local
kubectl describe node eastus-prod-local | grep -i arch

Check the architecture of the host:

uname -m
