I am trying to write a cloud-formation template for AWS ECS with blue green deployment support. This blue-green feature was added recently by AWS in ECS and couldn't find any reference for updating it in cloud-formation template. They have given documentation on, how to do it through UI but not through cloud-formation. I guess, AWS might not updated their cloud-formation documentation as it is a new feature. Any help to find the documentation would be appreciated. Thanking you in advance.

Amazon ECS supports creating clusters, task definitions, services, and task sets in AWS CloudFormation. The following examples demonstrate how to create resources with these templates using the AWS CLI.
The blue/green deployment process works as follows: Deploy new version—deploy the new (green) version alongside the current (blue) version. Test it to ensure it works as expected, and deploy changes to it if needed. Switch over traffic—when the new version is ready, switch overall traffic from blue to green.
Support for blue/green deployment in CloudFormation has been added. It can be found here in the documentation: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-service-deploymentcontroller.html
In the "Type" property you can choose "CODE_DEPLOY" as the deployment type. Hope this helps!
