Run Pi-hole on your UDM

Features

1. Run Pi-hole on your UDM with a completely isolated network stack. This will not port conflict or be influenced by any changes on by Ubiquiti
2. Persists through reboots and firmware updates.

Requirements

1. You have successfully setup the on boot script described here

Customization

• Feel free to change 20-dns.conflist to change the IP address and MAC address of the container.
• Update 10-dns.sh with your own values
• If you want IPv6 support use 20-dnsipv6.conflist and update 10-dns.sh with the IPv6 addresses. Also, please provide IPv6 servers to podman using --dns arguments.

Steps

1. On your controller, make a Corporate network with no DHCP server and give it a VLAN. For this example we are using VLAN 5.

2. Copy 20-dns.conflist to /mnt/data/podman/cni. This will create your podman macvlan network

3. Copy 10-dns.sh to /mnt/data/on_boot.d and update its values to reflect your environment

   ...
   VLAN=5
   IPV4_IP="10.0.5.3"
   IPV4_GW="10.0.5.1/24"
   ...
   CONTAINER=pihole
   ...
   

4. Execute /mnt/data/on_boot.d/10-dns.sh

5. Create directories for persistent Pi-hole configuration

   mkdir -p /mnt/data/etc-pihole
   mkdir -p /mnt/data/pihole/etc-dnsmasq.d
   

6. Create and run the Pi-hole docker container. The following command sets the upstream DNS servers to 1.1.1.1 and 8.8.8.8.

    podman run -d --network dns --restart always \
       --name pihole \
       -e TZ="America/Los Angeles" \
       -v "/mnt/data/etc-pihole/:/etc/pihole/" \
       -v "/mnt/data/pihole/etc-dnsmasq.d/:/etc/dnsmasq.d/" \
       --dns=127.0.0.1 \
       --dns=1.1.1.1 \
       --dns=8.8.8.8 \
       --hostname pi.hole \
       -e VIRTUAL_HOST="pi.hole" \
       -e PROXY_LOCATION="pi.hole" \
       -e ServerIP="10.0.5.3" \
       -e IPv6="False" \
       pihole/pihole:latest
   

   The below errors are expected and acceptable

   ERRO[0022] unable to get systemd connection to add healthchecks: dial unix /run/systemd/private: connect: no such file or directory
   ERRO[0022] unable to get systemd connection to start healthchecks: dial unix /run/systemd/private: connect: no such file or directory
   

7. Set pihole password

   podman exec -it pihole pihole -a -p YOURNEWPASSHERE
   

8. Update your DNS Servers to 10.0.5.3 (or your custom ip) for each of your Networks (UDM GUI | Networks | Advanced | DHCP Name Server)

9. Access the pihole like you would normally, e.g. http://10.0.5.3 if using examples above
