Eclipse-mosquitto on QNAP NAS

I want to set up an MQTT broker on my QNAP NAS (TS-230) so I’ve installed the ContainerStation and created an eclipse-mosquitto container. However, it starts in local mode only so I need to modify the config file. It says its loaded from /mosquitto/config/mosquitto.conf but I can’t find where this is located anywhere on the NAS. Has anyone done this kind of setup before?

I’ve made some progress. When eclipse-mosquitto is running there is a terminal option and running a shell allows the config file to be accessed and modified. I now have eclipse-mosquitto up and running with anonymous access but can’t find out how to access it. I’m using port 1883 but this is not open on the NAS. Running a docker inspect command shows no network information.

Finally figured it out. Just in case anyone else is struggling with this, here’s what I did:

  1. Install ContainerStation and open it
  2. Click Create and search for eclipse-mosquitto
  3. Leave everything at default except the command. Change the -c option to -c mosquito-no-auth.conf
  4. In Overview click on the eclipse-mosquitto-1 container
  5. Click Settings
  6. Click Advanced Settings
  7. Click Network and change Network Mode from NAT to Host
  8. Click Apply - mosquitto should restart and you’re good to go.

Hi, maybe a silly question, but how do you edit that config file? I can’t find that config file

That is the easiest way to setup Mosquitto MQTT to work in the QNAP

  1. Create mosquitto config file in text editor with name: mosquitto.conf
    File content:
    persistence true
    persistence_location /mosquitto/data
    listener 1883
    log_dest file /mosquitto/log/mosquitto.log
    log_timestamp_format %Y-%m-%dT%H:%M:%S
    allow_anonymous true
  2. Create a share folder: YOURFOLDERNAME on NAS or use existing one, then create subfolder name: mosquitto
  3. Upload the previously prepared file:‘‘mosquitto.conf’’ to folder : mosquitto
  4. In Container Station application click on ‘‘Create’’ - Then search for “eclipse mosquitto” in the list of available images , selecting “Docker Hub” as the source.
  5. Go to Advanced Settings →
    Network - Network Mode - NAT
    Host ->1883 Container ->1883 Protocol ->TCP
    Shared Folders → Add
    Volume from host → choose folder with mosquitto.conf file: YOURFOLDERNAME/mosquitto
    Mount point : “/mosquitto/config”
  6. Click on Create

MQTT should work now

If you want to setup an user.

  1. Open Mosquittto → Terminal → type ‘‘sh’’ and Enter
    type: ''mosquitto_passwd -c /mosquitto/config/pwfile YOURUSERNAME ‘’ → hit Enter
    Type twice YOURPASSWORD
    Exit terminal

update file “mosquitto.conf”
persistence true
persistence_location /mosquitto/data
listener 1883
log_dest file /mosquitto/log/mosquitto.log
log_timestamp_format %Y-%m-%dT%H:%M:%S
allow_anonymous false
password_file /mosquitto/config/pwfile
Restart Mosquitto container
Well done!
