Reference: AWS Batch job scenarios using EcsProperties

To illustrate how AWS Batch job definitions that use EcsProperties can be structured based on your needs, this topic presents the following RegisterJobDefinition payloads. You can copy these examples into a file, customize them to your needs, and then use the AWS Command Line Interface (AWS CLI) to call RegisterJobDefinition.
