NFO[0002] Successfully Deployed state file at [./rancher-cluster.rkestate]
INFO[0002] Building Kubernetes cluster
FATA[0002] Cluster must have at least one etcd plane host: please specify one or more etcd in cluster config
Please find the our yaml file configuration
nodes:
address: 192.168.X.2
user: sara
role: [controlplane,etcd]
address: 192.168.X.3
user: sara
role: [controlplane]
Please post the complete log, the top part will show it trying to connect to your nodes which probably fails, causing it not to be able to provision because its missing an etcd node in the cluster to provision. If it can’t connect to the node, you can check https://rancher.com/docs/rke/latest/en/troubleshooting/ssh-connectivity-errors/.
Thanks for your reply!! we are getting below error
