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
, "ImageKubernetesVersion" :String
, "ImageType" :String
}
YAML
ImageIdOverride:
String
ImageKubernetesVersion: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 thecomputeResource
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.

ImageKubernetesVersion
-
The Kubernetes version for the compute environment. If you don't specify a value, the latest version that Amazon Batch supports is used.
Required: No
Type: String
Minimum:
1
Maximum:
256
Update requires: Some interruptions
ImageType
-
The image type to match with the instance type to select an AMI. The supported values are different for
ECS
andEKS
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 animageId
nor aimageIdOverride
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
andG4
) and can be used for all non Amazon Graviton-based instance types. - ECS_AL2023
-
Amazon Linux 2023: Amazon 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 animageId
nor aimageIdOverride
parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Amazon 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
andG4
) and can be used for all non Amazon Graviton-based instance types.
