I have one CentOS vm (for install RKE) and 3 node installed rancherOS (vmware version from here for controlplane, etcd, and worker nodes)
I get "Finished building Kubernetes cluster successfully" message but I'm getting error while write "kubectl get nodes" command. After install rke, kubectl command didn't work and I installed it manually from official website.
Result:
In result when I run it with rancher user printing this error: Unable to connect to the server: net/http: TLS handshake timeout
with root: Error from server: etcdserver: request timed out
Where is the problem? Is my rke design correct?
RKE (one vm Centos)
- controlplane-etcd-worker node (rancherOS)
- controlplane-etcd-worker node (rancherOS)
- controlplane-etcd-worker node (rancherOS)
