不要将其标记为重复,因为我查看了其他答案,但它并没有解决我的问题.

我使用的是Windows 7和docker工具箱.

我正在做这个教程：
https://docs.microsoft.com/en-us/dotnet/csharp/tutorials/microservices

所以在这个命令之后：

docker run -d -p 80:5000 --name hello-docker weather-microservice

我无法达到http://localhost/

所以要解决它,我决定ping这个盒子.但我不能.

$docker ps
CONTAINER ID    IMAGE                   COMMAND                 CREATED         STATUS      PORTS                   NAMES

以下不起作用：

$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？
