How to configure Kubernetes cluster to preserve state and avoid recreating the entire cluster in case of etcd failure?
Ibrahim is looking for a way to configure the Kubernetes cluster to preserve its state and avoid recreating the entire cluster in case of etcd failure. He wants to save the state to S3 so that the cluster can be initiated without losing its state. The cluster is using a specific configuration provided in the discussion thread.

-
Ensure etcd data is persisted with a Persistent Volume (PV) to avoid data loss in case of failure.
-
Configure the cluster to save its state to S3 before termination, so it can be initiated with the same state automatically.
-
Check and update the YAML configurations to include persistency for etcd data.
-
Verify the
volumeClaimTemplatesconfiguration to ensure it aligns with the desired storage settings. -
Monitor the cluster to see if the problem reoccurs after making the necessary configurations.
