Ec2Configuration

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.

imageType

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 AWS 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 AWS Graviton-based instance types.
ECS_AL2023: Amazon Linux 2023: AWS Batch supports Amazon Linux 2023.

Note
Amazon Linux 2023 does not support A1 instances.
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 AWS Batch supports is used.

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 AWS Graviton-based instance types.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

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.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

imageKubernetesVersion

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

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No
