Question: Restore the original state of the cluster using the backup file.
What I did:
root@controlplane:~# ETCDCTL_API=3 etcdctl --endpoints 10.2.0.9:2379 snapshot restore /opt/snapshot-pre-boot.db 2021-06-01 12:59:04.425196 I | mvcc: restore compact to 1285 2021-06-01 12:59:04.435537 I | etcdserver/membership: added member 8e9e05c52164694d [<http://localhost:2380>] to cluster cdf818194e3a8c32
Source: https://kubernetes.io/docs/tasks/administer-cluster/configure-upgrade-etcd/ . In the solution stands that I need to change the path in the etcd yaml file in etc/kubernetes/manifests . Do I need to do that always? Where can I find that in the documentation?
