amazon.aws.ec2_vpc_subnet – Manage subnets in AWS virtual private clouds

Note

This plugin is part of the amazon.aws collection (version 1.5.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install amazon.aws.

To use it in a playbook, specify: amazon.aws.ec2_vpc_subnet.

New in version 1.0.0: of amazon.aws

Synopsis

  • Manage subnets in AWS virtual private clouds.

Requirements

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

  • boto
  • boto3
  • python >= 2.6

Parameters

Parameter Choices/Defaults Comments
assign_instances_ipv6
boolean
    Choices:
  • no
  • yes
Specify yes to indicate that instances launched into the subnet should be automatically assigned an IPv6 address.
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.
If profile is set this parameter is ignored.
Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_access_key, access_key
aws_ca_bundle
path
The location of a CA Bundle to use when validating SSL certificates.
Only used for boto3 based modules.
Note: The CA Bundle is read 'module' side and may need to be explicitly copied from the controller if not run locally.
aws_config
dictionary
A dictionary to modify the botocore configuration.
Only the 'user_agent' key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.
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.
If profile is set this parameter is ignored.
Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_secret_key, secret_key
az
string
The availability zone for the subnet.
cidr
string / required
The CIDR block for the subnet. E.g. 192.0.2.0/24.
debug_botocore_endpoint_logs
boolean
    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.

aliases: aws_endpoint_url, endpoint_url
ipv6_cidr
string
The IPv6 CIDR block for the subnet. The VPC must have a /56 block assigned and this value must be a valid IPv6 /64 that falls in the VPC range.
Required if assign_instances_ipv6=true
map_public
boolean
    Choices:
  • no
  • yes
Specify yes to indicate that instances launched into the subnet should be assigned public IP address by default.
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated.
aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.

aliases: aws_profile
purge_tags
boolean
    Choices:
  • no
  • yes
Whether or not to remove tags that do not appear in the tags list.
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
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.
If profile is set this parameter is ignored.
Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: aws_security_token, access_token
state
string
    Choices:
  • present
  • absent
Create or remove the subnet.
tags
dictionary
A dict of tags to apply to the subnet. Any tags currently applied to the subnet and not present here will be removed.

aliases: resource_tags
validate_certs
boolean
    Choices:
  • no
  • yes
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
vpc_id
string / required
VPC ID of the VPC in which to create or delete the subnet.
wait
boolean
    Choices:
  • no
  • yes
When wait=true and state=present, module will wait for subnet to be in available state before continuing.
wait_timeout
integer
Default:
300
Number of seconds to wait for subnet to become available wait=True.

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_PROFILE or AWS_DEFAULT_PROFILE, 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, AWS_CA_BUNDLE
  • 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
