NodegroupAmiType Enum ​

The AMI type for your node group.

GPU instance types should use the AL2_x86_64_GPU AMI type, which uses the Amazon EKS-optimized Linux AMI with GPU support or the BOTTLEROCKET_ARM_64_NVIDIA or BOTTLEROCKET_X86_64_NVIDIA AMI types, which uses the Amazon EKS-optimized Linux AMI with Nvidia-GPU support.

Non-GPU instances should use the AL2_x86_64 AMI type, which uses the Amazon EKS-optimized Linux AMI.
