Can't set up local DNS

Help docker
#1

Hi, there

I've installed pi-hole on my raspberry pi and used it as an ad-blocker for a while. I would like to also to benefit from it as a local DNS to use human-readable domains and not IP addresses, but I can't figure out what is wrong. I set up it via docker container with network_mode: "host", and added a DNS record in pi-hole gui (pi.local -> to 192.168.50.83 (IP of raspberry pi itself)), but still no effect

Expected Behaviour:

I can access pi not only via IP address, but also via domain name

Actual Behaviour:

In Google Chrome (macOS) I get DNS_PROBE_FINISHED_NXDOMAIN error while trying to navigate to http://pi.local/

The result of nslookup pi.local from my desktop is

Server:		192.168.50.83
Address:	192.168.50.83#53

Name:	pi.local
Address: 192.168.50.83

The result of dig pi.local from my desktop is

; <<>> DiG 9.10.6 <<>> pi.local

The result of ping pi.local from my desktop is:

ping: cannot resolve pi.local: Unknown host

To confirm, the desktop that you are testing the URI from is macOS?

Can you please do the same tests for the domain pi.hole?

#3

yes, macOS. DNS_PROBE_FINISHED_NXDOMAIN error while trying to navigate to http://pi.hole/

pi.hole should respond with the actual IP of the server, not 0.0.0.0. That indicates that the domain pi.hole is being blocked.

What does the web interface show for the domain request for pi.hole?

#5

Please post your docker-compose.yaml or your docker run command.

#6

how do I make domain request via the web interface?

docker-compose.yml:

version: "3"


services:
  pihole:
    image: pihole/pihole:latest
    hostname: pihole
    restart: unless-stopped
    env_file: ./pihole/.env
    network_mode: 'host'
    volumes:
      - './pihole/pihole:/etc/pihole'
      - './pihole/dnsmasq.d:/etc/dnsmasq.d'
    cap_add:
      - NET_ADMIN

.env:

TZ=Israel

I meant to have you make a query for pi.hole on a client that used Pi-hole for DNS and then check the query log on the web interface to see what the log shows as the source of the answer.

#9

but in the Pi-Hole Query Log page, it says Note: Queries for pi.hole and the hostname are never logged.. Should I temporarily disable it somehow?
