The Unifi-controller software is a powerful, enterprise wireless software engine ideal for high-density client deployments requiring low latency and high uptime performance.

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/unifi-controller:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

The webui is at https://ip:8443, setup with the first run wizard.

For Unifi to adopt other devices, e.g. an Access Point, it is required to change the inform IP address. Because Unifi runs inside Docker by default it uses an IP address not accessible by other devices. To change this go to Settings > System Settings > Controller Configuration and set the Controller Hostname/IP to a hostname or IP address accessible by your devices. Additionally the checkbox "Override inform host with controller hostname/IP" has to be checked, so that devices can connect to the controller during adoption (devices use the inform-endpoint during adoption).

In order to manually adopt a device take these steps:

ssh ubnt@$AP-IP
set-inform http://$address:8080/inform

The default device password is ubnt. $address is the IP address of the host you are running this container on and $AP-IP is the Access Point IP address.

When using a Security Gateway (router) it could be that network connected devices are unable to obtain an ip address. This can be fixed by setting "DHCP Gateway IP", under Settings > Networks > network_name, to a correct (and accessable) ip address.

Here are some example snippets to help you get started creating a container.

    image: lscr.io/linuxserver/unifi-controller:latest
    container_name: unifi-controller
    environment:

      - PGID=1000
      - MEM_LIMIT=1024 #optional
      - MEM_STARTUP=1024 #optional

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

When using volumes (-v flags) permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

• Shell access whilst the container is running: docker exec -it unifi-controller /bin/bash
• To monitor the logs of the container in realtime: docker logs -f unifi-controller
• container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' unifi-controller
• image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/unifi-controller:latest

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

• Update all images: docker-compose pull
  • or update a single image: docker-compose pull unifi-controller
• Let compose update all containers as necessary: docker-compose up -d
  • or update a single container: docker-compose up -d unifi-controller
• You can also remove the old dangling images: docker image prune

• Update the image: docker pull lscr.io/linuxserver/unifi-controller:latest
• Stop the running container: docker stop unifi-controller
• Delete the container: docker rm unifi-controller
• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
• You can also remove the old dangling images: docker image prune

• Pull the latest image at its tag and replace it with the same env variables in one run:

  docker run --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower \
  --run-once unifi-controller

• You can also remove the old dangling images: docker image prune

Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

• We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-unifi-controller.git
cd docker-unifi-controller
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/unifi-controller:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
