ec2_vpc_nat_gateway - Manage AWS VPC NAT Gateways.

New in version 2.2.

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
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
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.
ec2_url
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 Default:
no
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
(added in 1.6)
Uses a boto profile. Only works with boto >= 2.24.0.
region
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 Default:
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
(added in 1.6)
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
bool

(added in 1.5)
    Choices:
  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
wait Default:
no
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
