Container for the parameters to the ModifyInstanceAttribute operation. Modifies the specified attribute of the specified instance. You can specify only one attribute at a time.

To modify some attributes, the instance must be stopped. For more information, see Modifying Attributes of a Stopped Instance in the Amazon Elastic Compute Cloud User Guide.

The ModifyInstanceAttributeRequest type exposes the following members

Constructors

NameDescription
Public Method ModifyInstanceAttributeRequest()

Empty constructor used to set properties independently even when a simple constructor is available

Public Method ModifyInstanceAttributeRequest(string, InstanceAttributeName)

Instantiates ModifyInstanceAttributeRequest with the parameterized properties

Properties

NameTypeDescription
Public Property Attribute Amazon.EC2.InstanceAttributeName

Gets and sets the property Attribute.

The name of the attribute.

Public Property BlockDeviceMappings System.Collections.Generic.List<Amazon.EC2.Model.InstanceBlockDeviceMappingSpecification>

Gets and sets the property BlockDeviceMappings.

Modifies the DeleteOnTermination attribute for volumes that are currently attached. The volume must be owned by the caller. If no value is specified for DeleteOnTermination, the default is true and the volume is deleted when the instance is terminated.

To add instance store volumes to an Amazon EBS-backed instance, you must add them when you launch the instance. For more information, see Updating the Block Device Mapping when Launching an Instance in the Amazon Elastic Compute Cloud User Guide.

Public Property DisableApiTermination System.Boolean

Gets and sets the property DisableApiTermination.

If the value is true, you can't terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. You cannot use this parameter for Spot Instances.

Public Property EbsOptimized System.Boolean

Gets and sets the property EbsOptimized.

Specifies whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS Optimized instance.

Public Property EnaSupport System.Boolean

Gets and sets the property EnaSupport.

Set to true to enable enhanced networking with ENA for the instance.

This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

Public Property Groups System.Collections.Generic.List<System.String>

Gets and sets the property Groups.

[EC2-VPC] Changes the security groups of the instance. You must specify at least one security group, even if it's just the default security group for the VPC. You must specify the security group ID, not the security group name.

Public Property InstanceId System.String

Gets and sets the property InstanceId.

The ID of the instance.

Public Property InstanceInitiatedShutdownBehavior System.String

Gets and sets the property InstanceInitiatedShutdownBehavior.

Specifies whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).

Public Property InstanceType System.String

Gets and sets the property InstanceType.

Changes the instance type to the specified value. For more information, see Instance Types. If the instance type is not valid, the error returned is InvalidInstanceAttributeValue.

Public Property Kernel System.String

Gets and sets the property Kernel.

Changes the instance's kernel to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

Public Property Ramdisk System.String

Gets and sets the property Ramdisk.

Changes the instance's RAM disk to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

Public Property SourceDestCheck System.Boolean

Gets and sets the property SourceDestCheck.

Specifies whether source/destination checking is enabled. A value of true means that checking is enabled, and false means that checking is disabled. This value must be false for a NAT instance to perform NAT.

Public Property SriovNetSupport System.String

Gets and sets the property SriovNetSupport.

Set to simple to enable enhanced networking with the Intel 82599 Virtual Function interface for the instance.

There is no way to disable enhanced networking with the Intel 82599 Virtual Function interface at this time.

This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

Public Property UserData System.String

Gets and sets the property UserData.

Changes the instance's user data to the specified value. If you are using an AWS SDK or command line tool, base64-encoding is performed for you, and you can load the text from a file. Otherwise, you must provide base64-encoded text.

Public Property Value System.String

Gets and sets the property Value.

A new value for the attribute. Use only with the kernel, ramdisk, userData, disableApiTermination, or instanceInitiatedShutdownBehavior attribute.
