Properties
The ID of the Amazon Machine Image (AMI) that AWS PCS uses to launch instances.
If not provided, AWS PCS uses the AMI ID specified in the custom launch template.
The ID of the cluster of the compute node group.

notes
The role contained in your instance profile must have the pcs:RegisterComputeNodeGroupInstance permission and the role name must start with AWSPCS or must have the path /aws-pcs/ . For more information, see IAM instance profiles for AWS PCS in the AWS PCS User Guide .

notes
AWS PCS supports On-Demand Instances, Spot Instances, and Amazon EC2 Capacity Blocks for ML. For more information, see Amazon EC2 billing and purchasing options in the Amazon Elastic Compute Cloud User Guide . For more information about AWS PCS support for Capacity Blocks, see Using Amazon EC2 Capacity Blocks for ML with AWS PCS in the AWS PCS User Guide . If you don't provide this option, it defaults to On-Demand.
