Question

我正在尝试在Docker的容器中运行第二个Meteor应用程序。可以使用localhost:3000访问第一个（我正在运行的人），我希望在localhost:3003等其他端口中运行第二个。当我尝试访问第二个时，我得到了这个

无法访问此网站。 Localhost不允许连接。在Google上对localhost 3003进行一项研究。

如果我查看Docker，我可以看到我的容器正在运行：但我发现端口之间存在差异，可访问的端口为0.0.0.0:3000->3000/tcp，无法访问的端口为3000/tcp, 0.0.0.0:3003->3003/tcp，所以我认为此处存在问题。

在我的docker-compose.yml中，我做了：

app:
  image: jeromevi/controlcontainersapp
  ports:
    - "3003:3003"
  environment:
    - ROOT_URL=http://localhost:3003
    - MONGO_URL=mongodb://mongo:27017/meteor
mongo:
  image: mongo:latest

感谢您的帮助

[EDIT2]使用新配置时，错误是：

但我有网络测试Ntw：

我做了与答案

相同的docker-compose.yml

Answer 1

尝试以下方法：

sudo docker network create <your network name>

Docker撰写文件：

version: '2'
services:
  app:
    image: jeromevi/controlcontainersapp
    ports:
      - "3003:3000"
    environment:
      - ROOT_URL=http://localhost:3000
      - MONGO_URL=mongodb://mongo:27017/meteor
    networks:
      - <your network name>
  mongo:
    image: mongo:latest
    networks:
      - <your network name>
networks:
  <your network name>:
    external: true

然后在浏览器中查看此网址：

http://localhost:3003

<强>澄清：

使用默认网络，您需要使用links这是一项传统功能。我建议使用User-Defined个网络。 User-Defined内置了DNS个网络，因此您可以通过User-Defined从同一name网络上的其他容器连接到您的容器。在您的情况下，需要从名为mongo的容器中访问名为app的容器。
