问题描述
不要将其标记为重复项，因为我查看了其他答案，但不能解决我的问题。
Don't mark it as duplicate, because I looked at the other answers and it doesn't solve my problem.
我正在使用Windows 7和docker工具箱。
I am using Windows 7 and docker toolbox.
我正在学习本教程：
https://docs.microsoft.com/zh-cn/dotnet/csharp/tutorials/microservices
因此在此命令之后：
docker run -d -p 80:5000 --name hello-docker weather-microservice
我无法访问 http ：// localhost /
因此，要对其进行故障排除，我决定对此框执行ping操作。但是我不能。
So to troubleshoot it, I decided to ping the box. But I can't.
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
78179117b516 weather-microservice "dotnet out/Weathe..." 18 hours ago Up 18 hours 0.0.0.0:80->5000/tcp hello-docker
以下操作无效：
$ docker-machine ip weather-microservice
Host does not exist: "weather-microservice"
$ docker-machine ip hello-docker
Host does not exist: "hello-docker"
$ docker-machine ip 78179117b516
Host does not exist: "78179117b516"
$ docker inspect 78179117b516

所以当我这样做时：
$ ping 172.17.0.2
Pinging 172.17.0.2 with 32 bytes of data:
Request timed out.
这有效：
$ docker exec -it 78179117b516 ping www.google.com
PING www.google.com (172.217.3.196): 56 data bytes
64 bytes from 172.217.3.196: icmp_seq=0 ttl=53 time=5.412 ms
我做错了什么或我错过了什么？
What am I doing wrong or what am I missing?
推荐答案
实际上，我是从控制面板 \网络和Internet \网络连接中获得容器的IP的。有一个名为vEthernet（DockerNAT）的适配器，它是容器的适配器。我可以ping我为此适配器找到的IP。
Actually, I got the IP of my container from Control Panel\Network and Internet\Network Connections. There was an adapter called vEthernet(DockerNAT) and it was the container's adapter. I could ping the IP I found for this adapter.
