Cluster Configuration

After you provision a Kubernetes cluster using Rancher, you can still edit options and settings for the cluster.

For information on editing cluster membership, go to this page.

The cluster configuration options depend on the type of Kubernetes cluster:

Cluster Management Capabilities by Cluster Type​

The options and settings available for an existing cluster change based on the method that you used to provision it.

The following table summarizes the options and settings available for each cluster type:

  1. Registered EKS, GKE and AKS clusters have the same options available as EKS, GKE and AKS clusters created from the Rancher UI. The difference is that when a registered cluster is deleted from the Rancher UI, it is not destroyed.

  2. Cluster configuration options can't be edited for registered clusters, except for K3s and RKE2 clusters.

  3. For registered cluster nodes, the Rancher UI exposes the ability to cordon, drain, and edit the node.

  4. For registered clusters using etcd as a control plane, snapshots must be taken manually outside of the Rancher UI to use for backup and recovery.
