On cluster backup practice test:
I’ve applied:

ETCDCTL_API=3 etcdctl \
snapshot restore /opt/snapshot-pre-boot.db \
--data-dir=/var/lib/etcd-from-backup

Then changed the path in yaml:

But I am not getting any resources

Santosh Kaluskar:
Do I need to change the path in as well?

Command:
      etcd
      --data-dir=/var/lib/etcd
#3

Santosh Kaluskar:
Can someone please explain what are these commands:

--initial-cluster=master=<https://127.0.0.1:2380> \
     --initial-cluster-token=etcd-cluster-1 \
     --initial-advertise-peer-urls=<https://127.0.0.1:2380> \

I got these from this <https://discuss.kubernetes.io/t/etcd-backup-and-restore-management/11019/10|discuss link>

Alistair Mackay:
No, you only change the volume host path.
If the etcd server doesn’t restart you can do

systemctl restart kubelet

If it still doesn’t come up, you may have made a mistake, so reset the lab and try again

Santosh Kaluskar:
Thanks, I’ll try again. Before restore do I need to stop the kube-apiserver as explained by Mumshad in the video?

#6

Alistair Mackay:
You can. Its not always necessary though. Resetting everything is certainly a strategy for trying to restart a non functioning system :laughing:

Santosh Kaluskar:
Got this, Thanks a lot @Alistair Mackay
