Full Description



This is a containerized version of Ubiqiti Network's Unifi Controller version 5.

Use docker run --net=host -d jacobalberty/unifi:unifi5 to run it.

The following options may be of use:

  • Set the timezone with TZ
  • Bind mount the data and log volumes

Example to test with

mkdir -p unifi/data
mkdir -p unifi/logs
docker run --rm --net=host -e TZ='Africa/Johannesburg' -v ~/unifi/data:/var/lib/unifi -v ~/unifi/logs:/var/log/unifi --name unifi jacobalberty/unifi:unifi5

Mulit-process container

While micro-service patterns try to avoid running multiple processes in a container, the unifi5 container tries to follow the same process execution model intended by the original debian package and it's init script, while trying to avoid needing to run a full init system.

Essentially, dump-init runs a simple shell wrapper script placed at /usr/local/bin/ executes and waits on the jsvc process which orchestrates running the controller as a service. The wrapper script also traps SIGTERM to issue the appropriate stop command to the unifi java com.ubnt.ace.Launcher process in the hopes that it helps keep the shutdown graceful.

Example seen within the container after it was started

Future work?

  • Don't run as root (but Unifi's Debian package does by the way...)
  • Possibly use Debian image with systemd init included (but thus far, I don't know of an official Debian systemd image to base off)
