Is it possible to update the Cluster (Pod) CIDR or Service CIDR for an RKE, RKE2, or K3s cluster?
This document (000020221) is provided subject to the disclaimer at the end of this document.
Environment
An RKE, RKE2, or K3s cluster
Situation
The Cluster (Pod) CIDR (default 10.42.0.0/16) and Service CIDR (default 10.43.0.0/16) ranges for a cluster can be specified in the cluster configuration when launching an RKE, RKE2, or K3s cluster, whether provisioned directly or via Rancher v2.x. Is it possible to change these values after the cluster has been provisioned?
Resolution
Updating either the Cluster (Pod) CIDR or Service CIDR after the cluster has been provisioned is not supported and you should be careful to set these as required when first configuring the cluster.
