Cluster Config

sudo kubectl config get-contexts
sudo kubectl config use-context arn:aws:eks:us-east-2:972164494713:cluster/oneuptime-staging

Pods

sudo kubectl get pods

Persistent Volumes

sudo kubectl get pv

Pods are evicted

You might have to scale the cluster and add more nodes to it.

This usually happens when one of the nodes is out ot memory or disk. Ideally kill the cluster and create a new cluster.

Run this to delete evicted pods:

kubectl -n default delete pods --field-selector=status.phase=Failed
