You should setup the "Log Configuration" by specifying a log configuration in your task definition. I would recommend the awslogs configuration type, as this lets you see the logs from your container right inside the console.

Once you do that you will get a new tab on the task details screen called "Logs" and you can click that to see the output from your container as it was starting up. You will probably see some kind of error or crash as the "Essential container exited" error means that the container was expected to stay up and running, but it just exited.
