module: ec2_vpc_nat_gateway
short_description: Manage AWS VPC NAT Gateways.
description:
- Ensure the state of AWS VPC NAT Gateways based on their id, allocation and subnet ids.
version_added: "2.2"
requirements: [boto3, botocore]
options:
state:
description:
- Ensure NAT Gateway is present or absent.
default: "present"
choices: ["present", "absent"]
nat_gateway_id:
description:
- The id AWS dynamically allocates to the NAT Gateway on creation.
This is required when the absent option is present.
subnet_id:
description:
- The id of the subnet to create the NAT Gateway in. This is required
with the present option.
allocation_id:
description:
- The id of the elastic IP allocation. If this is not passed and the
eip_address is not passed. An EIP is generated for this NAT Gateway.
eip_address:
description:
- The elastic IP address of the EIP you want attached to this NAT Gateway.
If this is not passed and the allocation_id is not passed,
an EIP is generated for this NAT Gateway.
if_exist_do_not_create:
description:
- if a NAT Gateway exists already in the subnet_id, then do not create a new one.
required: false
default: false
release_eip:
description:
- Deallocate the EIP from the VPC.
- Option is only valid with the absent state.
- You should use this with the wait option. Since you can not release an address while a delete operation is happening.
default: 'yes'
wait:
description:
- Wait for operation to complete before returning.
default: 'no'
wait_timeout:
description:
- How many seconds to wait for an operation to complete before timing out.
default: 300
client_token:
description:
- Optional unique token to be used during create to ensure idempotency.
When specifying this option, ensure you specify the eip_address parameter
as well otherwise any subsequent runs will fail.

client (botocore.client.EC2): Boto3 client
nat_gateway_id (str): The Amazon nat id.
Kwargs:
wait (bool): Wait for the nat to be in the deleted state before returning.
wait_timeout (int): Number of seconds to wait, until this timeout is reached.
release_eip (bool): Once the nat has been deleted, you can deallocate the eip from the vpc.
Basic Usage:
>>> client = boto3.client('ec2')
>>> nat_gw_id = 'nat-03835afb6e31df79b'
>>> remove(client, nat_gw_id, wait=True, wait_timeout=500, release_eip=True)
