如何使用docker-compose在docker/container外部公开容器端口? [英] How to expose a container port outside of docker/container using docker-compose?

问题描述

我有一个具有多个端口的容器，我想以远程方式访问此Docker外部的端口之一(9001).

I have a container that it has several ports, I want to have access to one of its ports (9001) outside of this docker as remote.

• 我的docker IP是:172.17.0.1
• 我的容器IP是:172.19.0.23
• 我的服务器IP为:192.168.1.131

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

我已经搜索过此内容，却找到了expose port关键字，但确实做到了，但是没有用.

I have searched about that and I found expose port keyword, and I did it but not worked.

这是我的docker-compose文件:

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"  # exposed disired port
      ports:
        - "9001:9001"

---

我在docker-compose文件上方运行:$ docker-compose up -d

• 但是当我使用 server_IP:9001 --> 192.168.1.131:9001 或 docker_IP:9001 --> 172.17.0.1:9001 无法访问它(在远程或本地模式下)
• 但是使用 container_IP:9001 --> 172.19.0.23:9001 时， 在本地工作.

• But when I using server_IP:9001 --> 192.168.1.131:9001 or docker_IP:9001 --> 172.17.0.1:9001 can not access to that (in remote or local mode)
• But when using container_IP:9001 --> 172.19.0.23:9001 this works in local.

我应该怎么做才能访问 server_IP:9001 --> 192.168.1.131:9001 ?

What should I do that I can access to server_IP:9001 --> 192.168.1.131:9001?

[注意]:

在createDB.sh中的

• 运行若干操作，例如在上创建 ZMQ. 9001端口.

• In createDB.sh runs several operations such as creating a ZMQ on 9001 port.

我已经使用$ ufw allow 9001

任何帮助将不胜感激.

推荐答案

问题已通过以下说明解决:

Problem resolved with below instruction:

在ZMQ应用程序(在ivms容器中)中，我曾使用服务器IP来绑定连接，如下所示:

In ZMQ app (in ivms container) I had used from the server IP to binding a connection as follow:

import zmq

if __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()

它只能按以下方式工作:

It was working only as below:

socket.bind("tcp://192.168.1.131:9001")  # works, but can't access as remote

---

现在我按如下方式编辑此行:

socket.bind("tcp://*:9001")  # Works both locally and remotely.

这是我的docker-compose.yml配置:

And this is my docker-compose.yml configuration:

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"
      ports:
        - "9001:9001"
