Question:
kubectl config use-context cluster4
We tried to schedule grey-cka21-trb pod on cluster4 which was supposed to be deployed by the kubernetes scheduler so far but somehow its stuck in Pending state. Look into the issue and fix the same, make sure the pod is in Running state.
You can SSH into the cluster4 using ssh cluster4-controlplane command.
Answer:
The issue fixed in the scheduler pod and the scheduler pod is running but the scheduled pod grey is not running because of the image issue.
The same issue in some other pods as well.
