Hi there. I have a Kuberentes cluster being managed by Rancher (the K8s nodes are running on a Triton CN server), and this set up has been working just fine. However, I need to clear off the server these K8s nodes are running on because the server is being moved to a different data center. What I am trying to do is move/restore the application stack currently deployed on the existing cluster (and Triton CN) in a new cluster (different Triton CN). I have tried manually taking a backup on the
etcd
node (
etcdctl snapshot save snapshot.db
followed by
etcdctl snapshot restore snapshot.db
on the new node/cluster) as well as using the option in the Rancher UI to take a snapshot (RKE, which gets saved as a zip file on the
etcd
node in
/opt/rke/etcd-snapshots
) and then manually update and copy this zip file to the new
etcd
node for the new cluster and attempt to restore via Rancher UI (this is a weird process - I will explain what I did if needed). Neither of these attempts has worked - the manual
etcd
snapshot restore didn’t result in my application getting deployed, and the Rancher/RKE snapshot results in an error when I attempt to restore. Any help/guidance for moving a setup from one cluster to another would be greatly appreciated. Please let me know if more info or detail is needed. Thank you.
