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 added in 2.5	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. 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
az -		The availability zone for the subnet.
cidr -		The CIDR block for the subnet. E.g. 192.0.2.0/24.
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.
ipv6_cidr - added in 2.5		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 added in 2.4	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.
purge_tags boolean added in 2.5	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. aliases: access_token
state -	Choices: present ← absent	Create or remove the subnet
tags -		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 - / required		VPC ID of the VPC in which to create or delete the subnet.
wait boolean added in 2.5	Choices: no yes ←	When specified,state=present module will wait for subnet to be in available state before continuing.
wait_timeout - added in 2.5	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_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
