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.

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.
