Howdy Everyone!

As I am setting up my infrastructure at home using docker I wanted to ask, is it better to have DNS, something like pi-hole, on my main docker swarm or would it be better to have it on a dedicated machine/docker host separate from the rest of my infrastructure?

Thanks for the input!

Why not both?

My primary DNS is pihole on a rpi dedicated to the task; but I run a second instance of pihole via my main docker stack for redundancy. Should one or the other be unavailable, there's a second one to pick up the slack.

I just provide both DNS IPs to LAN clients via DHCP.

Gravity Sync is a great tool to keep both piholes settings/records/lists in sync.

Gravity sync looks cool but it looks like it was depreciated, any alternatives for it?

[–] Darkassassin07@lemmy.ca 2 points 1 month ago

Oh damn, I hadn't noticed. My setup is still functioning just fine.

There is an alternative though: Orbital-Sync

I haven't actually used it, so I can't say much about it; but I'll probably look into replacing gravity-sync with that.
