Job definitions

AWS 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.

Contents

• Creating a single-node job definition
• Creating a multi-node parallel job definition
• Creating job definitions using ContainerProperties
• Creating job definitions using EcsProperties
• Using the awslogs log driver
• Specifying sensitive data
• Private registry authentication for jobs
• Amazon EFS volumes
• Example job definitions

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 AWS permissions
