TL;DR

Keeps in close alignment with upstream Kubernetes.

RKE2 launches control plane components as static pods, managed by the kubelet.
It uses containerd as the embedded container runtime.

curl -sfL 'https://get.rke2.io' | sudo sh - \
&& sudo systemctl enable --now 'rke2-server.service'
Usage 
# Use the provided `kubectl`.
export KUBECONFIG='/etc/rancher/rke2/rke2.yaml' \
/var/lib/rancher/rke2/bin/kubectl get pods

# Restore clusters from snapshots.

  --cluster-reset-restore-path="/var/lib/rancher/rke2/server/db/etcd-old-${BACKUP_DATE}"
