## Synopsis

- Ensure the state of AWS VPC NAT Gateways based on their id, allocation and subnet ids.

## Requirements

The below requirements are needed on the host that executes this module.

- boto

- boto3

- botocore

- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
allocation_id - |  | 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.
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
client_token - |  | 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.

debug_botocore_endpoint_logs
boolean
added in 2.8

Choices:
- no ←
- yes

Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.

ec2_url string |  | Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
eip_address - |  | 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
boolean

Choices:
- no ←
- yes

if a NAT Gateway exists already in the subnet_id, then do not create a new one.

nat_gateway_id - |  | The id AWS dynamically allocates to the NAT Gateway on creation. This is required when the absent option is present.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region

release_eip
boolean

Choices:
- no
- yes ←

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.

security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token

state
-

Choices:
- present ←
- absent

Ensure NAT Gateway is present or absent.

subnet_id - |  | The id of the subnet to create the NAT Gateway in. This is required with the present option.

validate_certs
boolean

Choices:
- no
- yes ←

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

wait
boolean

Choices:
- no ←
- yes

Wait for operation to complete before returning.

wait_timeout - | Default: 300 | How many seconds to wait for an operation to complete before timing out.

## Notes

Note

- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence `AWS_URL` or `EC2_URL`, `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY` or `EC2_ACCESS_KEY`, `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY` or `EC2_SECRET_KEY`, `AWS_SECURITY_TOKEN` or `EC2_SECURITY_TOKEN`, `AWS_REGION` or `EC2_REGION`

- Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html

- `AWS_REGION` or `EC2_REGION` can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
