jacekkow/unifi repository overview

⁠UniFi

This is a Docker image of UniFi SDN controller based on openjdk:8-jre-slim

⁠Tags

Container is created for each stable UniFi release and tagged as vX.X.X. :latest tag is for the latest stable release (currently 5.13). :lts tag is for the latest 5.6 LTS release.

⁠Usage

docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	jacekkow/unifi

UniFi interface should be available at https://127.0.0.1:8443/⁠ (first run wizard is opened if the instance is unconfigured).

By default it uses Docker data volume for persistence.

You can update such installation by passing --volumes-from option to docker run:

docker pull jacekkow/unifi
docker stop unifi
docker rename unifi unifi-old
docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	--volumes-from unifi-old \
	jacekkow/unifi
docker rm -v unifi-old

⁠Local storage

If you prefer to have direct access to container's data from the host, you can use local storage instead of data volumes:

docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	-v /srv/unifi/data:/usr/lib/unifi/data \
	--user root \
	jacekkow/unifi

/srv/unifi/data directory will be automatically populated with default configuration if necessary.

File ownership is recursively changed to unifi:unifi (500:500) on each start, provided the container is run as root (don't worry - unifi user will be used to start UniFi).

⁠Captive portal and STUN

Using captive portal requires forwarding of additional ports (8880 and 8843):

docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	-p 8880:8880 -p 8843:8843 \
	jacekkow/unifi

For STUN (NAT traversal) UDP port 3478 must be available:

docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	-p 3478:3478/udp \
	jacekkow/unifi

Note that STUN was not tested in container-based environment! This port is also not exposed in Dockerfile.

⁠Configuration

You can configure the instance by editing files in directory /usr/lib/unifi/data inside the container (or appropriate host dir if local storage is used).

By default the JVM is started with option -Xmx1024m. You can override this default using JAVA_OPTS environment variable:

docker run -d --name=unifi \
	-p 8080:8080 -p 8443:8443 \
	-e "JAVA_OPTS=-Xmx512m" \
	jacekkow/unifi
