1. Install k8s using rke with 3 instance ( 1 t3a.large , 2 t3a.medium as etcd , controlplane and worker ) . Instaled k8s is working fine event get notify ingres nginx and admin but i can ignore it.  
2.Install rancher ( cert manager 1.6.0 and latest rancher using helm )  
3.Then i using AWS ALB as endpoint which target port 80 to instance k8s
2. The respond dashboard very slow and take a time to install rancher , event i must helm upgrade to push instalation since always time out .
3. The problem was gone if i only use 1 instance ( t3a.large)  
So any one here have good guide to install rancher in k8s using 3 node ?
