更改 docker-compose.yml 中的端口

Question

我正在按照官方文档学习如何使用docker-compose：https : //docs.docker.com/compose/gettingstarted/

浏览到http://myserver.com:5000 时，我得到了预期的结果：

Hello World! I have been seen 1 times.

我想将监听端口更改为 5001 修改docker-compose.yml文件如下：

version: '2'
  services:
    web:
      build: .
      ports:
       - "5001:5001"
      volumes:
       - .:/code
      depends_on:
       - redis
    redis:
      image: redis

Unfortunately, after stop and removing the container (with 'docker-compose down') and start it again (with 'docker-compose up -d'), the connection to http://myserver.com:5001 is refused.

Any idea?

Answer 1

您应该只更改外部端口（xxxx:xxxx 中的第一个端口号）

version: '2'
  services:
    web:
      build: .
      ports:
       - "5001:5000"
      volumes:
       - .:/code
      depends_on:
       - redis
    redis:
      image: redis
