Creating a task definition
In this section, we will create a task definition for a hello-world application using the tutum/hello-world Docker image. Another Docker image that exposes a HTTP port may also be used, but not all Docker images may be used. As an unsuitable example, the MySQL database Docker image, mysql, cannot be used with an application load balancer, as it exposes a TCP port, 3306. For an ECS task that exposes a TCP port, a network load balancer should be used.
