UniFi Network Controller not working as docker container

[boma]

Hi
I just got my T12-500 and startet to migrate the files and my containers from an old Synology DS1813+.

Portainer, SABNzbd, Jellyfin (with transcoding) are working fine (and much faster than on the Synology).

I took over the existing yaml for the UniFi Network Controller container. Changed the mongodb version, the P/GIDs and also the paths. The container images are downloaded, and the containers do start. No error message in Portainer, but the website for the unifi conroller doesn't show up. The two containers run and the unifi container does spike up CPU usage heavy every 10 seconds.

I can download the server.log in the unfi docker path. Looks like it can't login to the mongo db:

Here is my yaml fiel for the containers:

Code: Select all

services:
  unifi-db:
    image: docker.io/mongo:8.0.4
    container_name: unifi-db
    volumes:
    - /Volume1/public/docker/unifi-db/data/db:/data/db
    - /Volume1/public/docker/unifi-db/init-mongo.js:/docker-entrypoint-initdb.d/init-mongo.js:ro
    restart: unless-stopped

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

    restart: unless-stopped

and here is the init-mongo.js file:

Code: Select all

db.getSiblingDB("unifi-db").createUser({user: "unifi", pwd: "M-bWAu-x5mS+bWa", roles: [{role: "dbOwner", db: "unifi-db"}]});

db.getSiblingDB("unifi-db_stat").createUser({user: "unifi", pwd: "M-bWAu-x5mS+bWa", roles: [{role: "dbOwner", db: "unifi-db_stat"}]});

I tried different mogodb versions but no luck!

Anybody got this working or does have a clue, what I do wrong?

Thanks in advance!

I gave up and purchased the new fiber gateway with built in controller.
