AWS::Batch::ComputeEnvironment Ec2ConfigurationObject - Amazon CloudFormation
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

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).

Note

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

Syntax

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

JSON

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

YAML

ImageIdOverride: String ImageType: String

Properties

ImageIdOverride

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.

Note

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.

Required: No

Type: String

Minimum: 1

Maximum: 256

Update requires: No interruption

ImageType

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.

ECS_AL2

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

ECS_AL2_NVIDIA

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.

ECS_AL1

Amazon Linux. Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI.
