Packaged Component Versions

Known Issues

• #2309 - Custom Cluster CIDRs are not honored when using the Canal CNI Plugin. If you specify a --cluster-cidr other than 10.42.0.0/16, you should apply the following manifest to your cluster:

apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
  name: rke2-canal
  namespace: kube-system
spec:
  valuesContent: |-
    podCidr: $YOUR_CLUSTER_CIDR

• #1447 - When restoring RKE2 from backup to a new node, you should ensure that all pods are stopped following the initial restore:

curl -sfL https://get.rke2.io | sudo INSTALL_RKE2_VERSION=v1.20.11+rke2r1
rke2 server \
  --cluster-reset \
  --cluster-reset-restore-path=<PATH-TO-SNAPSHOT> --token <token used in the original cluster>
rke2-killall.sh
systemctl enable rke2-server
systemctl start rke2-server
