Kubernetes - Backup and Restore


How to backup and restore Kubernetes Cluster ?

Get the etcd binaries:
wget https://github.com/etcd-io/etcd/releases/download/v3.3.12/etcd-v3.3.12-linux-amd64.tar.gz
Unzip the compressed binaries:
tar xvf etcd-v3.3.12-linux-amd64.tar.gz
Move the files into /usr/local/bin:
sudo mv etcd-v3.3.12-linux-amd64/etcd* /usr/local/bin
Take a snapshot of the etcd datastore using etcdctl:
sudo ETCDCTL_API=3 etcdctl snapshot save snapshot.db --cacert /etc/kubernetes/pki/etcd/server.crt --cert /etc/kubernetes/pki/etcd/ca.crt --key /etc/kubernetes/pki/etcd/ca.key
View the help page for etcdctl:
ETCDCTL_API=3 etcdctl --help
Browse to the folder that contains the certificate files:
cd /etc/kubernetes/pki/etcd/
View that the snapshot was successful:
ETCDCTL_API=3 etcdctl --write-out=table snapshot status snapshot.db
Zip up the contents of the etcd directory:
sudo tar -zcvf etcd.tar.gz etcd
Copy the etcd directory to another server:
scp etcd.tar.gz cloud_user@18.219.235.42:~/
