/AWS1/CL_BTCEC2CONFIGURATION

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.

CONSTRUCTOR

IMPORTING

Required arguments:

iv_imagetype TYPE /AWS1/BTCIMAGETYPE /AWS1/BTCIMAGETYPE

The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.

ECS

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 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 Web Services Graviton-based instance types.

ECS_AL2023

Amazon Linux 2023: Batch supports Amazon Linux 2023.

Amazon Linux 2023 does not support A1 instances.

ECS_AL2023_NVIDIA

Amazon Linux 2023 (GPU): For all GPU instance families and can be used for all non Amazon Web Services Graviton-based instance types.

ECS_AL2023_NVIDIA doesn't support p3 and g3 instance types.

ECS_AL1

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

EKS

If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_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 EKS optimized AMI for that image type that Batch supports is used.

Starting end of October 2025 Amazon EKS optimized Amazon Linux 2023 AMIs will be the default on Batch for EKS versions prior to 1.33. Starting from Kubernetes version 1.33, EKS optimized Amazon Linux 2023 AMIs will be the default when it becomes supported on Batch.

Amazon Web Services will end support for Amazon EKS AL2-optimized and AL2-accelerated AMIs, starting 11/26/25. You can continue using Batch-provided Amazon EKS optimized Amazon Linux 2 AMIs on your Amazon EKS compute environments beyond the 11/26/25 end-of-support date, these compute environments will no longer receive any new software updates, security patches, or bug fixes from Amazon Web Services. For more information on upgrading from AL2 to AL2023, see How to upgrade from EKS AL2 to EKS AL2023 in the Batch User Guide.

EKS_AL2

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

EKS_AL2_NVIDIA

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

EKS_AL2023

Amazon Linux 2023: Batch supports Amazon Linux 2023.

Amazon Linux 2023 does not support A1 instances.

EKS_AL2023_NVIDIA

Amazon Linux 2023 (accelerated): GPU instance families and can be used for all non Amazon Web Services Graviton-based instance types.

Optional arguments:

iv_imageidoverride TYPE /AWS1/BTCIMAGEIDOVERRIDE /AWS1/BTCIMAGEIDOVERRIDE

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.

iv_imagekubernetesversion TYPE /AWS1/BTCKUBERNETESVERSION /AWS1/BTCKUBERNETESVERSION

The Kubernetes version for the compute environment. If you don't specify a value, the latest version that Batch supports is used.
