Maintaining an Openappstack cluster

Backup
Please take care to backup the following locations:

On your provisioning machine

Your cluster config directory where you put your inventory.yml and
settings.yml files. This is also the place where the generated secrets
are stored during installation. It's located under at openappstack/clusters


On your cluster

The local storage directories under /var/lib/OpenAppStack/local-storage.
This is the place all persistant volumes are stored.
Some are more important than others, if you want to hand-pick what volumes
to backup, use kubectl get pvc --all-namespaces to see which volumes are
used by what application. The prometheus volumes usually take the most space
for retaining metrics.
We recommend backing up the whole directory.
The rke directory /var/lib/OpenAppStack/rke
where the rke config and state file of your cluster is stored.
At this moment, recurring, automated etcd snapshots are not configured.
Please refer to the rke etc snapshot
documentation if you
like to backup etcd.

If you don't care about your backup disk usage too much, the easiest way is to
backup the whole /var/lib/OpenAppStack/ directory.
