Unifi Controller in a container

Notes for myself to run Unifi controller (and particularly MongoDB) in containers.

Following Unifi Network Application

• Create /opt/mongodb/docker-compose.yml

    version: "3"
  
    services:
      unifi-db:
        image: mongodb/mongodb-community-server:4.4.21-ubi8
        container_name: unifi-db
        volumes:
          - data:/data/db
          - ./init-mongo.js:/docker-entrypoint-initdb.d/init-mongo.js:ro
        restart: unless-stopped
  
    volumes:
      data:
        driver: local
        driver_opts:
          type: none
          device: ./data
          o: bind
  

  and /opt/mongodb/init-mongo.js (pick your own password and use it in unifi docker-compose)

    db.getSiblingDB("unifi").createUser(
  { user: "unifi", pwd: "SECRET_PASSWD", roles: [ {role: "dbOwner", db: "unifi" }, {role: "dbOwner", db: "unifi_stat"} ] });
  

• Start mongodb

    cd /opt/mongodb
    sudo docker-compose up -d
  

Install Unifi Controller

• Create /opt/unifi-network-application/docker-compose.yml

    version: "3"
  
    services:
      unifi-network-application:
        image: lscr.io/linuxserver/unifi-network-application:latest
        container_name: unifi-network-application
        environment:
          - PUID=1000
          - PGID=1000
          - TZ=Etc/UTC
          - MONGO_USER=unifi
          - MONGO_PASS=SECRET_PASSWD
          - MONGO_HOST=unifi-db
          - MONGO_PORT=27017
          - MONGO_DBNAME=unifi
          - MEM_LIMIT=1024      #optional
          - MEM_STARTUP=1024    #optional
        volumes:
          - data:/config
        ports:
          - 8443:8443
          - 3478:3478/udp
          - 10001:10001/udp
          - 8080:8080
          # - 1900:1900/udp #optional
          # - 8843:8843     #optional
          # - 8880:8880     #optional
          # - 6789:6789     #optional
          # - 5514:5514/udp #optional
        restart: unless-stopped
  
    volumes:
      data:
        driver: local
        driver_opts:
          type: none
          device: ./data
          o: bind
  

• Create data dir

    mkdir /opt/unifi-network-application/data
    chmod 770 /opt/unifi-network-application/data
  

• Start it up

    docker-compose up -d
  

• Import config from previous installation
