associate_address

Operation

associate_address async

associate_address(input: AssociateAddressInput, plugins: list[Plugin] | None = None) -> AssociateAddressOutput

Associates an Elastic IP address, or carrier IP address (for instances that are in subnets in Wavelength Zones) with an instance or a network interface. Before you can use an Elastic IP address, you must allocate it to your account.

If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance. If you associate an Elastic IP address with an instance that has an existing Elastic IP address, the existing address is disassociated from the instance, but remains allocated to your account.

[Subnets in Wavelength Zones] You can associate an IP address from the telecommunication carrier to the instance or network interface.

You cannot associate an Elastic IP address with an interface in a different network border group.

Warning

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error, and you may be charged for each time the Elastic IP address is remapped to the same instance. For more information, see the Elastic IP Addresses section of Amazon EC2 Pricing.

Parameters:

Name Type Description Default
input AssociateAddressInput

An instance of AssociateAddressInput.

required
plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.

None

Returns:

Type Description
AssociateAddressOutput

An instance of AssociateAddressOutput.

Input

AssociateAddressInput dataclass

Bases: _SerdeShape

Dataclass for AssociateAddressInput structure.

Attributes

allocation_id class-attribute instance-attribute
allocation_id: str | None = ...

The allocation ID. This is required.

allow_reassociation class-attribute instance-attribute
allow_reassociation: bool | None = ...

Reassociation is automatic, but you can specify false to ensure the operation fails if the Elastic IP address is already associated with another resource.

dry_run class-attribute instance-attribute
dry_run: bool | None = ...

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

instance_id class-attribute instance-attribute
instance_id: str | None = ...

The ID of the instance. The instance must have exactly one attached network interface. You can specify either the instance ID or the network interface ID, but not both.

network_interface_id class-attribute instance-attribute
network_interface_id: str | None = ...

The ID of the network interface. If the instance has more than one network interface, you must specify a network interface ID.

You can specify either the instance ID or the network interface ID, but not both.

private_ip_address class-attribute instance-attribute
private_ip_address: str | None = ...

The primary or secondary private IP address to associate with the Elastic IP address. If no private IP address is specified, the Elastic IP address is associated with the primary private IP address.

public_ip class-attribute instance-attribute
public_ip: str | None = ...

Deprecated.

Output

AssociateAddressOutput dataclass

Bases: _SerdeShape

Dataclass for AssociateAddressOutput structure.

Attributes

association_id class-attribute instance-attribute
association_id: str | None = ...

The ID that represents the association of the Elastic IP address with an instance.

response_metadata class-attribute instance-attribute
response_metadata: ResponseMetadata = ...

Metadata about the response that produced this output. Use this to recover the request identifiers a service's support team needs in order to investigate a call. Members of the metadata are individually optional.
