We want to create an cluster via RKE with 9 Nodes.
Is it better to give all 9 Nodes “worker, etcd, controlplane” ? Or should we give the 9 nodes only “worker” role and install 3 additional nodes with “etcd and controlplane” ? Can the cluster work with only 1 etcd and controlplane if 2 nodes go offline.
We need the lowest downtime.
Whats the best practis?
