Run AdguardHome on your UDM

Features

Run AdguardHome 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 setup the on boot script described here
AdguardHome persists through firmware updates as it will store the configuration in a folder (you need to create this). It needs 2 folders, a Work and Configuration folder. Please create the 2 folders in "/mnt/data/". In my example I created "AdguardHome-Confdir" and "AdguardHome-Workdir"

Customization

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

Copy 05-install-cni-plugins.sh to /mnt/data/on_boot.d
Execute /mnt/data/on_boot.d/05-install-cni-plugins.sh
On your controller, make a Corporate network with no DHCP server and give it a VLAN. For this example we are using VLAN 5. You should confirm the bridge is created for this VLAN by running netstat -r otherwise the script will fail. If it is not there, initiate a provisioning of the UDM (Controller > UDM > Config > Manage Device > Force provision).
Copy 10-dns.sh to /mnt/data/on_boot.d and update its values to reflect your environment
Copy 20-dns.conflist to /mnt/data/podman/cni after generating a MAC address. This will create your podman macvlan network.
Execute /mnt/data/on_boot.d/10-dns.sh

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

mkdir /mnt/data/AdguardHome-Confdir
mkdir /mnt/data/AdguardHome-Workdir

podman run -d --network dns --restart always  \
    --name adguardhome \
    -v "/mnt/data/AdguardHome-Confdir/:/opt/adguardhome/conf/" \
    -v "/mnt/data/AdguardHome-Workdir/:/opt/adguardhome/work/" \
    --dns=127.0.0.1 --dns=1.1.1.1 \
    --hostname adguardhome \
    adguard/adguardhome:latest

Browse to 10.0.5.3:3000 and follow the setup wizard
Update your DNS Servers to 10.0.5.3 (or your custom ip) in all your DHCP configs.
Access the AdguardHome like you would normally.

Troubleshooting

If you get the following error:

Error adding network: failed to create macvlan: cannot assign requested address

When starting the container then the MAC address you generated is not good. You can cheat at this point and look at the address of br$VLAN.mac with ifconfig br$VLAN.mac and use that value.

To start over you must remove the container and the macvlan device:

podman container rm adguardhome
podman network rm dns -f # expect an error here
ip link delete br$VLAN.mac

You can now run 10-dns.sh again and start the container again.
