Error: Address in use when deploying MQTT 2.0.14 as container using Docker Desktop

[RiteshKo]

I am trying to run mqtt as a container using Docker desktop. But as per the logs getting an error Address in use when running the command:

mosquitto -c mosquitto.conf

Below is my docker-compose file:

version: '3.5'

services:
  mosquitto:
    image: eclipse-mosquitto
    container_name: mosquitto_container
    ports:
      - 1883:1883
    volumes:
      - ./config:/mosquitto/config

And the mosquitto.conf file:

listener 1883 127.0.0.1
allow_anonymous true 

In all the articles over the internet and also in the mqtt docs it is mentioned that we have to specify listener in the conf file which I have added.

My goal is to run mqtt as a container and then from a .net utililty publish the messages to the broker.

I am using the Docker version v20.10.10 running on my Windows 10 and mqtt image version is 2.0.14.

Please guide me.

Same here

1689340436: mosquitto version 2.0.15 starting
1689340436: Config loaded from /mosquitto/config/mosquitto.conf.
1689340436: Opening ipv4 listen socket on port 1883.

1689340436: Opening ipv4 listen socket on port 1883.
1689340436: Error: Address in use

Why does it listen on ipv4 1883 twice?

config
