Thank you! I really recommend looking at RK3588 chips when upgrading from Raspberries, it’s a very capable chip with good mainline kernel support!

I recommend Talos even more though!

Renovate + GitOps. Check out https://github.com/onedr0p/cluster-template

If you don’t like Kubernetes, you can get a similar setup with doco-CD. Only limitation is that dococd can’t update itself, but you can use SOPS and Renovate all the same for the other services.
