I used https://github.com/jpetazzo/ampernetacle to provision resources and it’s been the “brain” for my personal cloud for this whole time. It doesn’t run much, basically ArgoCD, Tailscale operator and a CoreDNS deployment that does internal routing, but heck, it’s a free highly available control plane for an internal homelab. No other cloud even comes close to OCI’s offering, if you were to provision the same on other clouds it would be minimum $50 USD+ per month
Once it finally dies I’ll probably just go find some low cost provider like Hetzner or OVH to run this. I’m purposefully not really doing much on that instance as a result because I know that my small little bundle of terraform that builds out the vm’s will eventually need to be rewritten, so I’ve also purposefully avoided using any OCI specific constructs for my implementation.
