Fleet gitops into a k8s cluster provisioned by rancher into harvester.

Network(mikrotik) was done by hand. Installation of harvester by hand/iso, as is initial configuration and deployment of the k8s cluster.

I can deploy all my services into a k8s cluster with fleet. But up to having said cluster is “by hand”. Everything as code in terms of deployments, but Backups of any stateful data (databases, etc) if I’m honest need improvement. I’ve written some stuff to do one off dumps of databases to a NAS but I should automate it.

I have had to rebuild it all from scratch, and other than backup/restore of starteful data was quite happy. All applications, config, etc deploys nicely into a fresh cluster.
