Create resources declaratively and backup the yaml files in git
Taking immediate backup of all resources:
kubectl get all -A -o yaml > all-resources.yaml
restore:
kubectl apply -f all-resources.yaml
use Velero (previously ARK) by HeptIO for other resource-components
Method 2:
backup etcd data
In etc service configuration, check the etcd Data Dir. back it up.
Also, edctd Snapshot
etcdctl snapshot save snapshot.db
Restore
