Now start Redis by running the following (it might already be started):You now have Redis started in a Docker container. Amazon Elastic Container Service (Amazon ECS) is the Amazon Web Service you use to run Docker applications on a scalable cluster. Windows, then the web app should now be listening on port 5000 on your
