ClearOS Community basically died. They still exist but only to continue support for existing customers. It’s not active and it hasn’t really changed since 2013.
Basically, everything ClearOS does, another product does better and free-er. TrueNAS Scale for storage, Proxmox or XCP-NG for Virtualization, and both TrueNAS Scale and PVE have containerization support, so you can spin up the services you actually need using a technology that’s modern. For the full package, Univention basically took the ClearOS approach and made it on Ubuntu. In the network side, VyOS and PF/OpnSense took over routing, while the Sense products plus PiHole and AdGuard Home made DNS management easy.
No, that is exactly how you do it. It’s not a great name but you add a site, set up your registrar with what you need to point it at CF, and you’re up and running. Considering Cloudflare is mostly used to protect websites the names… clunky.
You don’t even need to register the domain through Cloudflare, you can just set up Cloudflare as the DNS master, and they’ll put in the right DNS records when you configure Email forwarding.
Netplan is pretty simple for what it is. All you need is the interface, address, and route, maybe DNS if you don’t want to set that up another way. Because it’s yaml, spacing matters, so watch that. You can use netplan try which will automatically revert if you don’t give it any input for a certain amount of time.
