Installing Unifi Controller as a Docker container on Synology

Having Ubiquiti UniFi access points in your house is a great way to serve a meshed Wifi network. With a Synology NAS and DSM6, it's very easy now to run the UniFi Controller in a Docker container. Link to the docker image: https://hub.docker.com/r/jacobalberty/unifi/
These tutorials will greatly help you with that: miketabor.com and kapsi.fi. There's a few tweaks I had to make:
Change the container config and add UDP port 10001:10001
Make sure your firewall rules on your NAS are properly adapted (take the 10001/udp into account as well)

If you have deployed a UniFi Controller on a different system/instance before, make sure that you adopt the device on your new Controller by doing the following steps:
SSH login to your access point (access_point_ip:22) with credentials of the previous controller (e.g. administrator:yoursecretpass)
Now execute the following commands:

#mca-cli
#set-inform synology_nas_ip:8080/inform

Now you should see your device into your new Controller instance and you're good to go!
