Warum kann ich den Docker-Container nicht anpingen?

Markiere es nicht als doppelt, da ich die anderen Antworten angeschaut habe und es mein Problem nicht löst.

Ich verwende Windows 7 und Docker-Toolbox.

Ich mache dieses Tutorial: https://docs.Microsoft.com/en-us/dotnet/csharp/tutorials/microservices

Also nach diesem Befehl:

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

Ich kann http: // localhost/ nicht erreichen

Um das Problem zu beheben, habe ich mich entschlossen, die Box zu pingen. Aber ich kann nicht.

$ 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

Folgendes funktioniert nicht:

$ 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

        }
    }
]

Wenn ich das mache:

$ ping 172.17.0.2

Pinging 172.17.0.2 with 32 bytes of data:
Request timed out.

Das funktioniert:

$ 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

Was mache ich falsch oder was fehle ich?
