DevOps engineers solve this problem using continuous delivery (CD) pipelines where developers check-in their code in a central code repository such as a Git repository, and container builds are automated using tools like Jenkins or CodePipeline. Although defining our stack in a JSON/YAML file requires going through a learning curve and forgetting about AWS management console and its truly easy to use wizards, it definitely pays off in the long run.

You can list registered Task Definitions with: By default, your ECS service will only have a private IP, and would typically be exposed publicly via an ELB. So using the CLI step earlier would create the cluster exactly the same. You don't need to worry about managing and scaling clusters. If you use an ECS Service instead of a task, you can put the service in a Target group and have an ELB point to it, and that is generally how I'd recommend exposing a web service from ECS. However, I'd do this by separating the containers out in the task definition. Whatever port we enter here will be opened on the instance and will map to the same port on container. In his role as Containers Specialist Solutions Architect at Amazon Web Services. Groups are what they sound like: groups of users that share access policies.
