How to expose a ZMQ container port outside of docker/container using docker-compose?

$

I have a container with several ports. I want remote access to the port 9001 outside of the container.

  • My docker IP is: 172.17.0.1
  • My container IP is: 172.19.0.23
  • My server IP is: 192.168.1.131

I have searched about this issue and I found the expose and ports attributes for ports forwarding but it did not work.

How to expose docker ports to make your containers externally accessible
Reference


This is my docker-compose file:

version: '3'services:  nginx:      image: nginx:latest      container_name: nginx      ports:        - "8010:8010"      volumes:        - .:/code        - ./nginx/default.conf:/etc/nginx/conf.d/default.conf      links:        - ivms      restart: unless-stopped  ivms:      build: .      container_name: ivms      command: bash bashes/createDB.sh      volumes:        - .:/code      expose:        - "8010"        - "9001"      ports:        - "9001:9001"

Here's the code snippet inside the ivms container:

import zmqif __name__ == '__main__':    context = zmq.Context()    socket = context.socket(zmq.SUB)    socket.setsockopt(zmq.SUBSCRIBE, "")    socket.bind("tcp://192.168.1.131:9001")  # doesn't work with server or docker IP    while True:        data = socket.recv_json()

I run the above docker-compose via docker-compose up -d

  • But when I use the server_IP:9001 which is 192.168.1.131:9001 ordocker_IP:9001 which is 172.17.0.1:9001 can not access either the remote or local mode.
  • But when using container_IP:9001 which is 172.19.0.23:9001 thisworks in local.

What should I do so that I can have access the server_IP:9001 --> 192.168.1.131:9001?


[NOTE]:

  • In createDB.sh runs several operations such as creating a ZMQ on9001 port.

  • I have been set the port allowing before, using $ ufw allow 9001

  • I tried on Ubuntu 16.04 and Ubuntu-Server 16.04


Any help would be appreciated.
