  # 1. In addition to your resource, if you need to access the resource from your ECS task 
  # then you need to create an AWS::IAM::ManagedPolicy that holds the permissions for your resource.
  #
  # For example, below is a sample policy for MyTable:
 

Outputs:
  # 1. You need to output the IAM ManagedPolicy so that Copilot can add it as a managed policy to your ECS task role.
  AppmeshResourceArn:
    Description: ARN of the VirtualNode
    Value: !Ref AppMeshVirtualNodeCrystal
  # 2. If you want to inject a property of your resource as an environment variable to your ECS task,
  # then you need to define an output for it.
  #
  # For example, the output MyTableName will be injected in capital snake case, MY_TABLE_NAME, to your task.
  # MyTableName:
  #   Description: "The name of this DynamoDB."
  #   Value: !Ref MyTable
