aws ec2 assign-private-ip-addresses
Assigns one or more secondary private IP addresses to the specified network interface. You can specify one or more specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned within the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For information about instance types, see Instance Types in the Amazon Elastic Compute Cloud User Guide. For more information about Elastic IP addresses, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide. When you move a secondary private IP address to another network interface, any Elastic IP address that is associated with the IP address is also moved. Remapping an IP address is an asynchronous operation. When you move an IP address from one network interface to another, check network/interfaces/macs/mac/local-ipv4s in the instance metadata to confirm that the remapping is complete. You must specify either the IP addresses or the IP address count in the request
Options
| Name | Description |
|---|---|
--allow-reassignment | Indicates whether to allow an IP address that is already assigned to another network interface or instance to be reassigned to the specified network interface |
--no-allow-reassignment | Indicates whether to allow an IP address that is already assigned to another network interface or instance to be reassigned to the specified network interface |
--network-interface-id <string> | The ID of the network interface |
--private-ip-addresses <list> | One or more IP addresses to be assigned as a secondary private IP address to the network interface. You can't specify this parameter when also specifying a number of secondary IP addresses. If you don't specify an IP address, Amazon EC2 automatically selects an IP address within the subnet range |
--secondary-private-ip-address-count <integer> | The number of secondary IP addresses to assign to the network interface. You can't specify this parameter when also specifying private IP addresses |
--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 |
