UniFi Controller

guide-by-example

Purpose & Overview

Ubiquiti managment software for wifi access points and other ubiquiti hardware.

UniFi is a web based managment software for Ubiquiti devices.
It is written in Java, utilizing the Spring Framework and using MongoDB as a database.

Docker image used here is provided by linuxserver.io

Files and directory structure

/home/
└── ~/
    └── docker/
        └── unifi/
            ├── config/
            ├── .env
            └── docker-compose.yml

config/ - a directory where unifi stores its coniguration data
.env - a file containing environment variables for docker compose
docker-compose.yml - a docker compose file, telling docker how to run the containers

You only need to provide the files.
The directory is created by docker compose on the first run.

docker-compose

docker-compose.yml

  unifi:
    image: linuxserver/unifi-controller

Reverse proxy

Caddy v2 is used, details here.

Caddyfile

unifi.{$MY_DOMAIN} {
        encode gzip
        reverse_proxy unifi:8443 {
                transport http {
                        tls
                        tls_insecure_skip_verify
                }
        }
}

Adoption

The controller might see your APs during initial setup, but it can not adopt them before you set your docker host IP as Override Inform Host.

Settings > System > Other Configuration
Override Inform Host check the Enable checbox
enter docker-host IP
adopt devices

Some Settings

Old interface > Wifi > advanced settings > disable "High Performance Devices"
When enabled it forces devices to ignore 2ghz band which obviously causes problems at range. Fucking monstrous stupidity.
DTIM sets to 3 for apple devices

Update

Manual image update:

docker-compose pull
docker-compose up -d
docker image prune

Backup and restore

Backup

Using borg that makes daily snapshot of the entire directory.

Restore

down the unifi container docker-compose down
delete the entire unifi directory
from the backup copy back the unifi directory
start the container docker-compose up -d
