Properties

BlockDeviceMappings

The block device mapping.

Required: No

Type: List of BlockDeviceMapping

Update requires: No interruption

CreditSpecification

The credit option for CPU usage of the instance. Valid for T2 instances only.

ElasticGpuSpecifications

An elastic GPU to associate with the instance.

Required: No

Type: List of ElasticGpuSpecification

Update requires: No interruption

IamInstanceProfile

The IAM instance profile.

Required: No

Type: IamInstanceProfile

Update requires: No interruption

ImageId

The ID of the AMI. For more information, see DescribeImages in the Amazon EC2 API Reference.

Required: No

Type: String

Update requires: No interruption
