Synopsis

Syntax

Edit-EC2InstancePlacement
-InstanceId <String>
-Affinity <Affinity>
-GroupName <String>
-HostId <String>
-PartitionNumber <Int32>
-Tenancy <HostTenancy>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Modifies the placement attributes for a specified instance. You can do the following:
  • Modify the affinity between an instance and a Dedicated Host. When affinity is set to host and the instance is not associated with a specific Dedicated Host, the next time the instance is launched, it is automatically associated with the host on which it lands. If the instance is restarted or rebooted, this relationship persists.
  • Change the Dedicated Host with which an instance is associated.
  • Change the instance tenancy of an instance from host to dedicated, or from dedicated to host.
  • Move an instance to or from a placement group.
At least one attribute for affinity, host ID, tenancy, or placement group name must be specified in the request. Affinity and tenancy can be modified in the same request. To modify the host ID, tenancy, placement group, or partition for an instance, the instance must be in the stopped state.

Parameters

-Affinity <Affinity>
The affinity setting for the instance.

-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Return'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.ModifyInstancePlacementResponse). Specifying the name of a property of type Amazon.EC2.Model.ModifyInstancePlacementResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.

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.

Position? Named
Accept pipeline input? True (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. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

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.
