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
我无法访问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
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？
实际上，我从控制面板\网络和 Internet\网络连接中获得了容器的 IP。有一个名为 vEthernet(DockerNAT) 的适配器，它是容器的适配器。我可以 ping 为这个适配器找到的 IP。
如Docker 已知限制中所述：
\n\n\n适用于 Windows 的 Docker Desktop 可以\xe2\x80\x99t 将流量路由到 Linux 容器。但是，您可以 ping Windows 容器。
\n
因此，在尝试将容器从 Windows 主机 ping 到 Linux 容器时请记住这一点。您可能想使用publish的功能docker run来启用端口转发。
It's because, the ip address you see via docker inspect command, is used by docker for internal networking and communication. It's not accessible from outside. Also, localhost won't work, since you are running docker toolbox, which runs inside ubuntu VM. You have to get the ip address of the VM first by,
docker-machine ls
如果我的内存服务正确且工具箱在Mac和Windows中工作相同,则IP地址应为192.168.99.100.因此,您将能够通过http://192.168.99.100访问您的应用.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.
