Kubernetes - how to list conditions that are not met

Question

I upgraded k8s version on GCP to 1.21.6-gke.1500. Some of my pods are stuck in the status "ContainerCreating". When I describe them, I see these errors:

Events:
  Type     Reason       Age                    From               Message

How to list conditions which are not met and pods are waiting for them?

Answer 1

Try following commands:

kubectl describe pod <name>
kubectl get nodes -o wide
kubectl get volumeattachments
kubectl get componentstatus

You can also check your GKE Logs.
