I had added these host names to /etc/hosts on the nodes, they can be resolved via DNS, too, so I wonder WTH?

rancher.yml is

ignore_docker_version: false
ssh_key_path: ~/.ssh/id_ecdsa
network:
  # plugin: canal
  plugin: flannel
  # flannel on lxc has problems
nodes:
  - address: rr01.ac.example.com
    user: debian
    role: [controlplane,worker,etcd]
  - address: rr02.ac.example.com
    user: debian
    role: [controlplane,worker,etcd]
  - address: rr03.ac.example.com
    user: debian
    role: [controlplane,worker,etcd]
services:
  etcd:
    snapshot: true
    creation: 6h
    retention: 24h

Every helpful comment is highly appreciated

The output of the following commands would help in diagnosing the issue:

  • kubectl --kubeconfig kube_config_rancher.yml get nodes from the node you are running rke up from
  • docker logs kubelet from the cluster nodes

I have found the problem: Even though the nodes were wiped out using extended-cleanup-rancher2.sh rke up found and used a local rkestate file from a previous attempt. After removing it rke went fine.

But now Rancher is not working. No web interface, i.e. a problem with ingress. I will create a new thread for this.

Thanx for your reply
