title: Why does the connect-datagen container of my confluent kafka docker-compose disconnect after a couple of minutes?
body: <p>I am trying to run a bare minimum confluent community example on docker for windows (toolbox) using the example given here:</p>
  <p><a href="https://docs.confluent.io/current/quickstart/cos-docker-quickstart.html" rel="nofollow noreferrer">https://docs.confluent.io/current/quickstart/cos-docker-quickstart.html</a></p>
  <p>but seems like all components gets started only connect is failing of them does not work,
