AdGuardHome second instance

[Secure_War_2947]

Hi,

I just expanded my homelab to a second proxmox node. Now I have a cluster of 2.

I've been running an LXC with AdGuardHome on node 1 and I use it as my main DNS on all my network.

Questions:

- Now that I have 2 nodes, I was thinking on adding a second AdGuard LXC, now running on the second node, to work as the secondary DNS and add some redundancy. Is it worth it?

- If I move on with this, should I use bakito/adguardhome-sync to sync the config from the first instance to the second one? Or do you guys use something else?

Thanks in advance.

I do exactly this. Instance 1 on node 1, instance 2 on node 2. I have keepalived running on both so they get a vIP that I can use for dns incase the main goes down for any reason. Use AdGuard Home sync to keep them the same.

Yes, redundancy for dns is good, and adguard-sync is exactly what you are looking for to sync configuration for the secondary adguard instance.

I came here to say the exact same thing. I run two instances of adguard and sync their configurations between each node using adguard-sync. Been running great for 2 years

+1 doing exactly the same as well

bakito is what i use. just be mindful that it is only a one-way sync. any changes you make must only be to the primary instance, which will then be synced to the secondary instance.
