Create a single-node job definition
Before you can run jobs in AWS Batch, you must create a job definition. This process varies slightly between single-node and multi-node parallel jobs. This topic covers specifically how to create a job definition for an AWS Batch job that's not a multi-node parallel job (also known as gang scheduling).
You can create a multi-node parallel job definition on Amazon Elastic Container Service resources. For more information, see Create a multi-node parallel job definition.
