what is the Best way to make a Cluster inter-site with dynamic IP ?

[JOduMonT]

Hi everyone;

I have 3proxmox I want to put into a single cluster but they are on different site and 2 of them are reachable via dynamic IP.

My questions are:
it is possible to build a cluster over dns (nameserver) instead of IP ?
such as I could use a dyndns client to renew the IP.

Would be more diligent/intelligent to build the cluster over VPN kind like tinc or zerotier and fix the IP of these node ?

Do anybody have a proof of concept and/or did this ?

Regards!

Hi,

theoretically yes, but in reality, this does not work.
The latency will be too high and with DNS resolving it will increase even more.

The Proxmox Cluster is not made for WAN usage.
