docker - 如何制作Network_Mode : "host" work in docker-compose. yml文件

Question

我正在尝试执行“ docker-compose up ”命令。请在下面找到我的docker-compose文件。我尝试了 network_mode:“主机” ，但是它不起作用。我在Linux OS上。要求您让我知道我是否犯了任何错误。

version: '3.6'
services:
   mongo:
      image: "mongo:latest"
      container_name: ohif-mongo
       ports:
         - "27017:27017"

   viewer:
      image: ohif/viewer:latest
      container_name: ohif-viewer
      ports:
        - "3030:80"
      network_mode: "host"   # please make note of the alignment
      links:
         - mongo
      environment:
         - MONGO_URL=mongodb://mongo:27017/ohif
      extra_hosts:
         - "pacsIP:172.xx.xxx.xxx"
      volumes:
         - ./dockersupport-app.json:/app/app.json

执行后，出现以下错误

ERROR: for 8f4c3de7e3a3_ohif-viewer  Cannot create container for service viewer: conflicting options: host type networking can't be used with links. This would result in undefined behavior
 ERROR: for viewer  Cannot create container for service viewer: conflicting options: host type networking can't be used with links. This would result in undefined behavior

我不知道为什么错误消息会显示两次。不确定这是否是预期的

其次，当我更改network_mode的对齐方式时:“主机”(减1/2个空格)

  ports:
        - "3030:80"
        network_mode: "host"   # please see the change in alignment now
      links:
         - mongo

我收到以下错误消息

ERROR: yaml.parser.ParserError: while parsing a block mapping
 in "./docker-compose.yml", line 10, column 5
expected <block end>, but found '<block mapping start>'
 in "./docker-compose.yml", line 14, column 6

如何以网络=主机模式启动容器？

Answer 1

network_mode: host用于与主机共享相同的网络空间。例如，您可能想从容器访问Linux PC上运行的应用程序。
如果要将服务链接在一起，则可以使用links或depends_on，并且如果服务位于不同的主机上，则只需创建一个覆盖网络即可
