Amazon Elastic Compute Cloud

2022/11/17 - Amazon Elastic Compute Cloud - 1 updated api methods

Changes  This release adds a new optional parameter "privateIpAddress" for the CreateNatGateway API. PrivateIPAddress will allow customers to select a custom Private IPv4 address instead of having it be auto-assigned.

CreateNatGateway (updated) Link ΒΆ
Changes (request) 
{'PrivateIpAddress': 'string'}

Creates a NAT gateway in the specified subnet. This action creates a network interface in the specified subnet with a private IP address from the IP address range of the subnet. You can create either a public NAT gateway or a private NAT gateway.

With a public NAT gateway, internet-bound traffic from a private subnet can be routed to the NAT gateway, so that instances in a private subnet can connect to the internet.

With a private NAT gateway, private communication is routed across VPCs and on-premises networks through a transit gateway or virtual private gateway. Common use cases include running large workloads behind a small pool of allowlisted IPv4 addresses, preserving private IPv4 addresses, and communicating between overlapping networks.

For more information, see NAT gateways in the Amazon Virtual Private Cloud User Guide .

type AllocationId

string

param AllocationId

[Public NAT gateways only] The allocation ID of an Elastic IP address to associate with the NAT gateway. You cannot specify an Elastic IP address with a private NAT gateway. If the Elastic IP address is associated with another resource, you must first disassociate it.

type ClientToken

string

param ClientToken

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to ensure idempotency .

Constraint: Maximum 64 ASCII characters.

This field is autopopulated if not provided.

type DryRun

boolean

param DryRun

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 .

type SubnetId

string

param SubnetId

[REQUIRED]

The subnet in which to create the NAT gateway.

type TagSpecifications

list

param TagSpecifications

The tags to assign to the NAT gateway.

  • (dict) --

    The tags to apply to a resource when the resource is being created.

    Note

    The Valid Values lists all the resource types that can be tagged. However, the action you're using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you're using, you'll get an error.

    • ResourceType (string) --

      The type of resource to tag on creation.

    • Tags (list) --

      The tags to apply to the resource.

      • (dict) --

        Describes a tag.

        • Key (string) --

          The key of the tag.

          Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with aws: .

        • Value (string) --

          The value of the tag.

          Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

type ConnectivityType

string

param ConnectivityType

Indicates whether the NAT gateway supports public or private connectivity. The default is public connectivity.

type PrivateIpAddress

string

param PrivateIpAddress

The private IPv4 address to assign to the NAT gateway. If you don't provide an address, a private IPv4 address will be automatically assigned.

rtype

dict

returns
