I recently replaced an old WiFi router with an Ubiquiti UniFi U6+. I connected it to a Ubiquiti UniFi Switch Lite 8 PoE.
To manage Ubiquiti devices, you need the UniFi Network Application, which can be run from a dedicated device or from a Docker image. As you might know, I’m a big fan of running certain applications as Docker containers on my Synology DiskStation.
I have installed this Docker image with help from this guide. After starting the container, I could log in and start adopting my devices.
The devices were found, but remained stuck in the “Adopting” status. I did a factory reset for both devices, but nothing changed. After reading the documentation more thoroughly (#protip), I found an explanation.
Override "Inform Host" IP
For your Unifi devices to "find" the Unifi Controller running in Docker, you MUST override the Inform Host IP with the address of the Docker host computer. (By default, the Docker container usually gets the internal address 172.17.x.x while Unifi devices connect to the (external) address of the Docker host.) To do this:
Find Settings -> System -> Other Configuration -> Override Inform Host: in the Unifi Controller web GUI. (It's near the bottom of that page.)
Check the "Enable" box, and enter the IP address of the Docker host machine.
Save settings in Unifi Controller
Restart UniFi-in-Docker container
The above was copied from the docs.
Now my devices were adopted and I could continue setting them up and integrate them into the home network.
