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.
Syntax
To declare this entity in your AWS 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 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.

ImageType
-
The image type to match with the instance type to select an AMI. If the

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 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
andG4
) and can be used for all non AWS Graviton-based instance types. - ECS_AL1
-
Amazon Linux. Amazon Linux is reaching the end-of-life of standard support. For more information, see Amazon Linux AMI
