Unable to connect from outside the Mosquitto docker

I'm running Mosquitto 2.0.7 as a docker.

If I try to use mosquitto_sub from within the docker I can do it. If I try it from a different machine I get connection refused.

The docker is running exposing port 1883 and 9001. The docker is runing on host network. There is no error on the docker log.

Thanks

It seems at some point, the location of the config file was changed.

As long as the network_mode is set to "host" and the config file gets copied into the correct folder in the container then the following yml/configs should work without issue as of 2.0.14:

docker-compose.yml:

version: "3"
services:
  mosquitto:
    image: eclipse-mosquitto:latest
    container_name: mosquitto
    network_mode: "host"
    volumes:
      - ./conf:/mosquitto/config
      - ./data:/mosquitto/data
      - ./log:/mosquitto/log

conf/mosquitto.conf

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
listener 1883 0.0.0.0

## Authentication ##
allow_anonymous true
#password_file /mosquitto/conf/mosquitto.conf

Issuing plain-old sudo docker-compose up -d should work, exposing the ports on the host's network.

I had same issue. try this changes in ./services/mosquitto/mosquitto.conf: add, replace or verify at your config file this lines:

allow_anonymous true
listener 1883
persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log

and restart your container mosquitto.

I have my Mosquitto Docker container configured with a port 1883, and that seems to bind it to 0.0.0.0, which allows for access from outside the container. Be sure you also expose the port in your startup command:

docker run -d --name="mosquitto" -p 1883:1883 prologic/mosquitto
