title: How to wait for Zalenium service ready state in docker-compose file?
body: <p>I'm using zalenium using docker-compose file for executing my test case. But my test cases are failing because of zalenium service not in a ready state.</p>
  <p>I tried a couple of options like the WAIT_FOR_HOSTS option of docker-compose but the issue is zalenium grid is getting started at port 4444 and nodes are not yet registered. which takes some time to in a ready state</p>
