Manifests

The ECS CLI manifest describes the application’s infrastructure as code. It is a file generated from ecs-preview init or ecs-preview app init that AWS CloudFormation can understand. Unlike raw CloudFormation templates, the manifest describes the architecture of the application and not the individual resources in its infrastructure.

Manifest files are stored under the ecs-project/ directory and end with -app.yml.
