Thanks!

Please dont link with a Google Amp link.

Just a quick thought. These days you can create a special partition in the first part of your drive and just boot from it. No grub, no config really. You might want to take a look at EFI and an EFI system partition perhaps?

I would also say this. Njalla is good

Tailscale maybe? They have a mode where you can configure a site to site links, you could route the docker networks. https://tailscale.com/kb/1019/subnets
