aws ec2 modify-hosts

Modify the auto-placement setting of a Dedicated Host. When auto-placement is enabled, any instances that you launch with a tenancy of host but without a specific host ID are placed onto any available Dedicated Host in your account that has auto-placement enabled. When auto-placement is disabled, you need to provide a host ID to have the instance launch onto a specific host. If no host ID is provided, the instance is launched onto a suitable host with auto-placement enabled. You can also use this API action to modify a Dedicated Host to support either multiple instance types in an instance family, or to support a specific instance type only

Options

NameDescription
--auto-placement <string>Specify whether to enable or disable auto-placement
--host-ids <list>The IDs of the Dedicated Hosts to modify
--host-recovery <string>Indicates whether to enable or disable host recovery for the Dedicated Host. For more information, see Host recovery in the Amazon EC2 User Guide
--instance-type <string>Specifies the instance type to be supported by the Dedicated Host. Specify this parameter to modify a Dedicated Host to support only a specific instance type. If you want to modify a Dedicated Host to support multiple instance types in its current instance family, omit this parameter and specify InstanceFamily instead. You cannot specify InstanceType and InstanceFamily in the same request
--instance-family <string>Specifies the instance family to be supported by the Dedicated Host. Specify this parameter to modify a Dedicated Host to support multiple instance types within its current instance family. If you want to modify a Dedicated Host to support a specific instance type only, omit this parameter and specify InstanceType instead. You cannot specify InstanceFamily and InstanceType in the same request
--cli-input-json <string>Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally
--generate-cli-skeleton <string>Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command
