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。
我正在使用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
我无法联系到http://localhost/
因此，为了解决问题，我决定对该框进行ping操作。但我不能。
$ 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？
答案 0 :(得分：6)
这是因为，您通过docker inspect命令看到的IP地址被docker用于内部网络和通信。它无法从外部访问。此外，localhost将无法工作，因为您正在运行在ubuntu VM中运行的docker工具箱。您必须首先获取VM的IP地址，
docker-machine ls
如果我的内存正常，并且工具箱在Mac和Windows中的工作方式相同，则IP地址应为192.168.99.100。因此，您可以通过http://192.168.99.100访问自己的应用。除了这些之外，为什么还在使用泊坞工具箱。新方法是用于windows的mac / docker的docker。这样更容易，更有效率。首先，您将能够通过localhost访问您的应用程序，而无需知道IP地址。
答案 1 :(得分：4)
实际上，我从Control Panel \ Network和Internet \ Network Connections获得了我的容器的IP。有一个名为vEthernet（DockerNAT）的适配器，它是容器的适配器。我可以ping我找到的适配器的IP。
答案 2 :(得分：2)
用于Windows的Docker桌面无法将流量路由到Linux容器。但是，您可以ping Windows容器。
因此，当尝试从Windows主机到Linux容器ping容器时，请记住这一点。您可能想使用publish的{{1}}功能来启用端口转发。
答案 3 :(得分：1)
10次中的9次，它是Windows防火墙。
完全禁用Windows防火墙 - 将其关闭 - 看看是否可以访问您的网站。
答案 4 :(得分：0)
类似于Ehsan Mirsaeedi所说的，但对我来说，正确的选择是vEthernet（默认交换机）。还在Windows docker container cannot ping host
