Keepalived with Pihole for DNS HA
In my previous post about my DNS, I mentioned there that I migrated Pihole from Unraid to my Proxmox hosting my router. But in fact, on top of that, I left an instance of Pihole on Unraid running inside a LXC container. Together with that I also configured keepalived for high availability. Hosting the DNS on the same hypervisor as my router should already be sufficient (I’d say my OPNsense VM is more likely to face issues than a LXC container) but I still wanted to try out an use case for keepalived....
