  PartitionNumber = NULL,
  HostResourceGroupArn = NULL,
  GroupId = NULL,
  InstanceId,
  Tenancy = NULL,
  Affinity = NULL,
  HostId = NULL
)

Arguments

GroupName

The name of the placement group in which to place the instance. For spread placement groups, the instance must have a tenancy of default. For cluster and partition placement groups, the instance must have a tenancy of default or dedicated.

To remove an instance from a placement group, specify an empty string ("").

PartitionNumber

The number of the partition in which to place the instance. Valid only if the placement group strategy is set to partition.

HostResourceGroupArn

The ARN of the host resource group in which to place the instance. The instance must have a tenancy of host to specify this parameter.

GroupId

The Group Id of a placement group. You must specify the Placement Group Group Id to launch an instance in a shared placement group.

InstanceId

[required] The ID of the instance that you are modifying.

Tenancy

The tenancy for the instance.

For T3 instances, you must launch the instance on a Dedicated Host to use a tenancy of host. You can't change the tenancy from host to dedicated or default. Attempting to make one of these unsupported tenancy changes results in an InvalidRequest error code.

Affinity

The affinity setting for the instance. For more information, see Host affinity in the Amazon EC2 User Guide.

HostId

The ID of the Dedicated Host with which to associate the instance.
