Create a k3s cluster on Oracle Cloud's free for life tier.
This was initially based on this Medium article
Trying to make the setup more stable and tailored to my needs which are:
- No separate "DB" machine; databases can run on the cluster too
- One x86 master and an aarch64 worker node
- Make the loadbalancer and ingress use 443 and 80, and have a cert-manager for letsencrypt certificates
- Be able to use any ports? -> eg for a jamulus server
- Try and use longhorn or something so we have a distributed persistent storage
Oracle Cloud was chosen due to their very generous free tier.

- Web analytics
- Tailscale VPN
- Cgit
- TBD
- fix iptables so metrics etc work
- Set in cloud-init does not survive reboot - make it permanent
- Fix nginx-controller
- resource requests so HPA can work
- Make sure that the controller pod(s) do(es) not start on server
- Try out loadbalancer
- Make a network loadbalancer for non-http traffic
- Try out trafik instead of nginx as ingress
- Long goal - longhorn?
