Question: Kube Linode Backups? about kube-linode HOT 1 OPEN

Hi @cboothe, thanks for raising this issue! Unfortunately Linode backups will not work on coreos images because of their unique partitioning scheme (see https://linode.com/docs/tools-reference/custom-kernels-distros/install-coreos-on-your-linode/).

For etcd backups, you can follow this guide (https://coreos.com/etcd/docs/latest/v2/admin_guide.html) with the appropriate environmental variables set pointing to the etcd certs located in the cluster/ folder.

As for persistent storage backups, assuming you are using persistent volumes via Rook, unfortunately there is no out of the box solution for snapshots, though I see work is planned to support such a feature (see rook/rook#1552) would should hopefully be available soon :) If you are just looking for high availability, you can tune the number of replicas / error correction etc in the manifest before running the script (see https://github.com/kahkhang/kube-linode/blob/master/manifests/rook/rook-storageclass.yaml)

Assuming you're using the kube-linode setup out of the box, I think etcd and persistent volumes are probably the only things that you need to backup in order for disaster recovery.
