-
The ARN of the container instance (if it was previously registered).
Type: String
Required: No
- instanceIdentityDocument
-
The instance identity document for the EC2 instance to register. This document can be found by running the following command from the instance:

Type: String
Required: No
- instanceIdentityDocumentSignature
-
The instance identity document signature for the EC2 instance to register. This signature can be found by running the following command from the instance:
