Verify cluster

How to verify an EKS Anywhere cluster is running properly

To verify that a cluster control plane is up and running, use the kubectl command to show that the control plane pods are all running.

kubectl get po -A -l control-plane=controller-manager
NAMESPACE                           NAME                                                             READY   STATUS    RESTARTS   AGE

You may also check the status of the cluster control plane resource directly. This can be especially useful to verify clusters with multiple control plane nodes after an upgrade.

kubectl get
supportbundletestcluster   true          true                   v1.20.7-eks-1-20-6   1          1       1

To verify that the expected number of cluster worker nodes are up and running, use the kubectl command to show that nodes are Ready. This will confirm that the expected number of worker nodes are present. Worker nodes are named using the cluster name followed by the worker node group name (example: my-cluster-md-0)

kubectl get nodes
NAME                                           STATUS   ROLES                  AGE    VERSION
supportbundletestcluster-md-0-55bb5ccd-mrcf9   Ready    <none>                 4m   v1.20.7-eks-1-20-6
supportbundletestcluster-md-0-55bb5ccd-zrh97   Ready    <none>                 4m   v1.20.7-eks-1-20-6
supportbundletestcluster-mdrwf                 Ready    control-plane,master   5m   v1.20.7-eks-1-20-6

To test a workload in your cluster you can try deploying the hello-eks-anywhere .
