Hi! I took my CKA exam yesterday, I got the question about ssh into node, and perform back up and restore of etcd with peer.key and peer.crt. If I passed those in when backing up, I received “no such file or directory” error on the peer.crt/peer.key. Any idea what to do here? Can’t find any examples out there that does this either. I also tried server.crt and server.key, but all I got was “permission denied”, so I suspect I have to authenticate with the peer flags somehow(?) These peer flags were also not present when checking the etcd pod’s commands. I do see in the docs, under Securing Communication that there are some peer flags for configuring etcd with secure peer comm., but these flags were unknown to the etcdctl tool

[@devopshub]

As per my knowledge, we do not use peer.crt and peer.key for taking etcd backups. The peer certificates (peer.crt and peer.key) are used for communication between etcd nodes in a clustered environment (peer-to-peer communication). When taking a backup of etcd, you should use server.crt, server.key, ca.crt

Hi @devopshub...need one clarification we are restoring the snapshot at new directory that is /var/lib/etcd-new right. But can we restore an etcd snapshot directly into the existing etcd data directory that is /var/lib/etcd i meam override the /var/lib/etcd data by restoring snapshot...if possible so we dont need to modify the etcd.yaml file... Thaks in advanced 🙏

[@aravindravikumar248]

That will throw an error saying the directory already exists. We can restore the snapshot only to a new directory. If you really font want to edit the etcd.yaml, you Mal pls delete the directory /var/lib/etcd first before restoring. But it is not recommended.
