Master node - moving to a different server


#1

hey guys,

1.) how does the recommended way look like for moving a master node (etcd, controlplane) to a different server. i am uncertain because of this issue https://github.com/rancher/rancher/issues/14102 the new master node would have a new ip address.

2.) what is technically the difference between --address and --internal-address with regard to the " Rancher Agent Options" https://rancher.com/docs/rancher/v2.x/en/admin-settings/agent-options/
is it possible to build a 3 node cluster (1 master - 2 worker) inside a private vlan/subnet and to control the external access to the cluster through a firewall (inbound - dnat / outbound - snat) ?
if this would be possible then i dont understand the meaning of the options “–address and --internal-address”.

i would welcome your response.

best regards
Masi
