03/15/2023, 11:33 AMOne of the biggest difference between RKE and RKE2 is that RKE requires docker and RKE2 does not.

03/15/2023, 11:35 AMThanks …but in rke how can I add another master in kube config …let’s say 3 master to add in kube config and I don’t need to create load balancer
I heard that rke by default add only one master in kube config

03/15/2023, 11:38 AMGreat thanks 🙏 let me go through this
ok so after I add that new master in cluster.yml file in rke …do I need to restart the rke service ?
how it will add the new master in kubeconfig which has already created at beginning ?

03/15/2023, 1:00 PMIts been a while since I did this, but if I remember correctly you have to do "rke up --config /path-to-your-cluster.yml"

03/22/2023, 1:09 PMYes for RKE. If you do not want to setup SSH then use RKE2. https://docs.rke2.io/install/requirements
