Run PiHole on your UDM

Features

  1. 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
  2. Persists through reboots and firmware updates.

Requirements

  1. You have successfully setup the on boot script described here
  2. 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 10-dnsipv6.sh and change the docker command to IPv6=True. 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. Install the CNI plugins with by executing install-cni-plugins.sh on your UDM

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

  4. Copy 10-dns.sh to /mnt/data/on_boot.d and update its values to reflect your environment (specifically the container name)

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

  6. 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

  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) in all your DHCP configs.

  9. Access the pihole like you would normally.
