Hi guy’s, i’m trying to simulate different scenario for etcd backup and restore, but but i’m stuck here, i can’t copy the db etcd file from node01 to controlplane via SCP. Is the transfer file from node01 to controlplane is not authorized?

Zack:
Why would you need to switch between nodes? You can take backup from any place if the etcdctl and certs are present.

Amel ECHEIKH EZAOUALI:
so i have to copy etdcd yaml file to node01 and make required change and point kublet on it to run etcd pod on node01?

Amel ECHEIKH EZAOUALI:
as static pod

Amel ECHEIKH EZAOUALI:

Himadri Ganguly:
