Run PiHole on your UDM

Features

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

Requirements

You have successfully setup the on boot script described here
PiHole persists through firmware updates. The on-boot script does not. If you update your firmware, setup on-boot again and everything should work.

Customization

Feel free to change 20-dns.conflist to change the IP 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

On your controller, make a Corporate network with no DHCP server and give it a VLAN. For this example we are using VLAN 5.
Copy 10-dns.sh to /mnt/data/on_boot.d and update its values to reflect your environment
Execute /mnt/data/on_boot.d/10-dns.sh
Copy 20-dns.conflist to /mnt/data/podman/cni. This will create your podman macvlan network

Run the pihole docker container, be sure to make the directories for your persistent pihole configuration. They are mounted as volumes in the command below.

 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 \
    --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

Set pihole password

podman exec -it pihole pihole -a -p YOURNEWPASSHERE

Update your DNS Servers to 10.0.5.3 (or your custom ip) in all your DHCP configs.
Access the pihole like you would normally.
