Run Ubiquiti Networks UniFi Controller in Docker. See https://hub.docker.com/r/silug/unifi/ for more information.
To use, run something like this:
mkdir -pv /srv/docker/unifi-store/{run,log,lib}
docker pull silug/unifi
docker run -p 8080:8080 -p 8443:8443 -p 8880:8880 -p 8843:8843 -p 3478:3478/udp --name=unifi --rm -v /srv/docker/unifi-store/run:/var/run/unifi -v /srv/docker/unifi-store/log:/var/log/unifi -v /srv/docker/unifi-store/lib:/var/lib/unifi silug/unifi
(You might need to preface the port mappings with the local IP address (-p localip:8080:8080, for example) to get Docker to bind to the right IP.)
Once set up, to run automatically under systemd, use a unit file like this:
[Unit]
Description=Unifi controller
Requires=docker.service
After=docker.service
[Service]

Restart=on-failure
RestartSec=10
