Job definitions
Amazon Batch job definitions specify how jobs are to be run. While each job must reference a job definition, many of the parameters that are specified in the job definition can be overridden at runtime.
Some of the attributes specified in a job definition include:
-
Which Docker image to use with the container in your job.
-
How many vCPUs and how much memory to use with the container.
-
The command the container should run when it is started.
-
What (if any) environment variables should be passed to the container when it starts.
-
Any data volumes that should be used with the container.
-
What (if any) IAM role your job should use for Amazon permissions.
