AWS::Batch::ComputeEnvironment Ec2ConfigurationObject

Provides information used to select Amazon Machine Images (AMIs) for instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 (Amazon Linux 2).


This object isn't applicable to jobs that are running on Fargate resources.


To declare this entity in your Amazon CloudFormation template, use the following syntax:


{ "ImageIdOverride" : String, "ImageType" : String }


ImageIdOverride: String ImageType: String



The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.


The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.

The image type to match with the instance type to select an AMI. If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Amazon Batch is used.


Amazon Linux 2: Default for all non-GPU instance families.


Amazon Linux 2 (GPU): Default for all GPU instance families (for example P4 and G4) and can be used for all non Amazon Graviton-based instance types.
