title: Why can't I ping docker container on Windows?
body: <p>Don't mark it as duplicate, because I looked at the other answers and it doesn't solve my problem.</p>
  
  <p>I am using Windows 7 and docker toolbox.</p>
  
  <p>I am doing this tutorial:
  <a href="https://docs.microsoft.com/en-us/dotnet/csharp/tutorials/microservices" rel="noreferrer">https://docs.microsoft.com/en-us/dotnet/csharp/tutorials/microservices</a></p>
  
  <p>So after this command:</p>
  
  <pre><code>docker run -d -p 80:5000 --name hello-docker weather-microservice
  </code></pre>
  
  <p>I am not able to reach <a href="http://localhost/" rel="noreferrer">http://localhost/</a></p>
  
  <p>So to troubleshoot it, I decided to ping the box. But I can't.</p>
  
  <pre><code>$ 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-&gt;5000/tcp    hello-docker
  </code></pre>
  
  <p>The following doesn't work:</p>
  
  <pre><code>$ 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
