I just recently began utilizing GKE. For a week, I diligently worked on spinning up a cluster. The prior cluster and its components seem to have appeared now, however there appears to be a cluster-level error stating that "The cluster has some problem" at the cluster level. "Couldn't get data from Cluster" is what I saw when I checked the nodes tab in Cluster. There is no problem with the compute engine, however these errors are displayed at the cluster.
I tried restarting the cluster a few times because I felt it was taking a while for the node to attach to it.
Follow below troubleshooting steps to resolve your issue:
First, I advise you to see if your project and your billing account are connected
Next, use the commands kubectl cluster-info shows the cluster information.
kubectl get pod -n kube-system, is the kubectl command is used to show the detailed status of the Kubernetes pods
kubectl get nodes that give fundamental data about the hubs in your Kubernetes bunch. At the point when you execute this command , it speaks with the Kubernetes Programming interface server, recovering the vital data from the group's control plane.
Try kubectl describe node <node> to see the current state of your cluster.
Additionally, look for any issues in the logs under Stackdriver -> Logging -> Logs viewer.
Try contacting Billing Support if you were unable to find any issues.
