cdk8s works really nicely with gitops.

Back when it was a single node cluster, I just used hostFolder mounts with restic backups. I added Longhorn once the cluster grew, but there's still some local hostFolder mounts left around. For example, zigbee2mqtt needs to be on the node that has the zigbee controller plugged into it, so the node is tagged and zigbee2mqtt has a nodeSelector. This means the hostPath still works and I haven't needed to migrate it to Longhorn.

Longhorn initially scared me off with its relatively high listed resource requirements, but after configuring it to not run on the RPis it turned out to work quite well, most of the time just using a few percent CPU.
