Unraid Pi-hole Docker Issue

[FAZIN]

I've been trying for an hour but I can't get any Pi-hole app on Unraid to work for me.

Using the binhex-official-pihole app I can never connect to the WebUI, and the log stops on an error 

 

Using the Pihole-DoT-Doh app with the same settings, I can get into the WebUI but I get Error (-2) in the Domains on List box.

Not sure if the issues are linked or if there was a prerequisite setting I needed to configure, but none of the fixes I can find on Google solve the issue. Any leads would be much appreciated!

I’d double check the container template in Unraid and make sure both /etc/pihole and /etc/dnsmasq.d are mapped to persistent paths on your array or cache drive.

Also, the ‘DNS resolution is currently unavailable’ error means Pi-hole can’t reach upstream DNS on first boot, so it can’t build the gravity list. Try setting an explicit DNS in the container settings like 1.1.1.1 or 8.8.8.8 and restart.

Verify volume mappings.

Make sure /etc/pihole is writable.

Set an upstream DNS manually for first boot.

Once those are fixed, the WebUI should come up and gravity.db will be created.

That did it! Thanks!

Awesome, glad it worked!

If you're going to use google or cloudflare dns; I'd also recommend setting up a DoH / DoT recursive proxy like Cloudflared or Unbound; then you point your Pi-Hole to your DoH/DoT Proxy as the upstream. That way your DNS will be secured over TLS. 

 

That might be what the 'pihole-doh-dot' container is; which means you have to configure the external dns in the recursive proxy part of it rather than the pihole upstream.
