Developers package their code into a container image that includes the application code, libraries, and any other dependencies. A policy is a collection of permissions for a specified services. Yes, think of it like Lamdas. Given that Jenkins requires data persistence, you needed EC2 instances to run a Jenkins cluster in the past. I would not install docker or related tools and manage the containers myself because that defeats half the point of ECS. 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. In the real world it is unlikely that you would need to create these permissions for yourself. The kaniko executor container in this pod will clone to code from the sample code repository, build a container image using the Dockerfile in the project, and push the built image to ECR.
