Description

Modifies the specified attribute of the specified instance. You can specify only one attribute at a time. Note: Using this action to change the security groups associated with an elastic network interface (ENI) attached to an instance in a VPC can result in an error if the instance has more than one ENI. To change the security groups associated with an ENI attached to an instance that has multiple ENIs, we recommend that you use the ModifyNetworkInterfaceAttribute action. 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.

Parameters

-Attribute <InstanceAttributeName>
The name of the attribute.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-BlockDeviceMapping <InstanceBlockDeviceMappingSpecification[]>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesBlockDeviceMappings
-DisableApiTermination <Boolean>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-EbsOptimized <Boolean>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-EnaSupport <Boolean>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Group <String[]>
[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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesGroupId, Groups
-InstanceId <String>
The ID of the instance.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-InstanceInitiatedShutdownBehavior <String>
Specifies whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-InstanceType <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Kernel <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the InstanceId parameter. The -PassThru parameter is deprecated, use -Select '^InstanceId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Ramdisk <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The cmdlet doesn't have a return value by default. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.ModifyInstanceAttributeResponse). Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SourceDestCheck <Boolean>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SriovNetSupport <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UserData <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Value <String>
A new value for the attribute. Use only with the kernel, ramdisk, userData, disableApiTermination, or instanceInitiatedShutdownBehavior attribute.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
