Day 4 has been all about getting some services moved over to the K8s cluster.
I've been starting first with my uptime-kuma instance, but have been getting an odd error around the SOPS secret management / encryption.
I'm pretty sure this is an issue with the remote storage. I'm using, democratic-csi's drivers for Truenas and even though they are reporting as all green this is the first deployment I'm using it on; so I wouldn't be surprised if there were something going wrong under the hood that is manifesting itself on deployment of uptime kuma.
The next step will be to try another deployment for my pfsense-backup setup which will use the same storage. If that works then it's an issue with my uptime-kuma config; if not it's the storage.
