Connecting to mosquitto (docker) #1104

Open alexchern opened 5 years ago

alexchern commented 5 years ago

Hi guys,

A newbie question… This is my docker-compose file:

version: '3'
services:  
  mosquitto:
    container_name: eclipse-mosquitto
    image: eclipse-mosquitto
    restart: always   
    ports:
      - '1883:1883'
      - '9001:9001'      
    volumes:
      - mosquittodata:/data
volumes:
  mosquittodata:

When I run it, everything seems to be Ok, but … I cannot connect to the broker from the host computer:

C:\Program Files (x86)\mosquitto>mosquitto_pub -h 127.0.0.1 -t 'test/topic' -m "Hello"
Error: No connection could be made because the target machine actively refused it.

What is wrong? Any ideas?

Thanks,

Alex

By default docker runs on the bridge network 172.17.0.0/16. Find the container's IP address by docker inspect eclipse-mosquitto and connect to that IP Address instead of 127.0.0.1

Hi,

Thanks for your help.

docker inspect eclipse-mosquitto

brings me the following: 

$ docker inspect eclipse-mosquitto

So, I tried to connect to 172.26.0.5, but it didn't help :-(

Thanks,

I have the same problem.You can try "IPAddress": "172.26.0.5" as host inside another container.

I had the same issue. My solution was to add two env variables to the docker-compose file for PUID: 1883 and PGID: 1883.

may be it will help: switch off your "MQTT broker" Service in Windows, and 1883 port will be accessible.

1883 port is free, but then also it's not working.
