Deploying your application to an ECS cluster

Deploying to ECS is seamless; however, we need to create a profile on Docker that will use AWS credentials to be able to interact with AWS and provision resources.

Therefore, we need to create a Docker Context that’s specific to AWS ECS scenarios:

$ docker context create ecs guide-to-compose
? Create a Docker context using:  [Use arrows to move, type to filter]
> An existing AWS profile
  AWS secret and token credentials
  AWS environment variables
? Select AWS Profile  [Use arrows to move, type to filter]
  default
> guide-to-docker-compose
Successfully created ecs context "guide-to-compose"

By using the credentials, the context will try to provision infrastructure or evaluate if infrastructure already exists for the Compose application. Thus, it is important for the user/role behind the AWS profile to have sufficient permissions for those actions.
