Parameters

Parameter	Comments
access_key aliases: aws_access_key_id, aws_access_key, ec2_access_key string	AWS access key ID. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference. The aws_access_key and profile options are mutually exclusive. The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
assign_instances_ipv6 boolean	Whether instances launched into the subnet should default to being automatically assigned an IPv6 address. If assign_instances_ipv6=true, ipv6_cidr must also be specified. Choices: false ← (default) true
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. The AWS_CA_BUNDLE environment variable may also be used.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.
az string	The availability zone for the subnet. Required if outpost_arn is set.
cidr string / required	The CIDR block for the subnet. E.g. 192.0.2.0/24.
debug_botocore_endpoint_logs boolean	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. Choices: false ← (default) true
endpoint_url aliases: ec2_url, aws_endpoint_url, s3_url string	URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS. The AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference. The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.
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 Default: ""
map_public boolean	Whether instances launched into the subnet should default to being assigned public IP address. Choices: false ← (default) true
outpost_arn string	The Amazon Resource Name (ARN) of the Outpost. If set, allows to create subnet in an Outpost. If outpost_arn is set, az must also be specified. Default: ""
profile aliases: aws_profile string	A named AWS profile to use for authentication. See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html. The AWS_PROFILE environment variable may also be used. The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.
purge_tags boolean	If purge_tags=true and tags is set, existing tags will be purged from the resource to match exactly what is defined by tags parameter. If the tags parameter is not set then tags will not be modified, even if purge_tags=True. Tag keys beginning with aws: are reserved by Amazon and can not be modified. As such they will be ignored for the purposes of the purge_tags parameter. See the Amazon documentation for more information https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html#tag-conventions. Choices: false true ← (default)
region aliases: aws_region, ec2_region string	The AWS region to use. For global services such as IAM, Route53 and CloudFront, region is ignored. The AWS_REGION or EC2_REGION environment variables may also be used. See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region. The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01 Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.
secret_key aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key string	AWS secret access key. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference. The secret_key and profile options are mutually exclusive. The aws_secret_access_key alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_secret_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
session_token aliases: aws_session_token, security_token, aws_security_token, access_token string	AWS STS session token for use with temporary credentials. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SESSION_TOKEN, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variables may also be used in decreasing order of preference. The security_token and profile options are mutually exclusive. Aliases aws_session_token and session_token were added in release 3.2.0, with the parameter being renamed from security_token to session_token in release 6.0.0. The security_token, aws_security_token, and access_token aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY and AWS_SECURITY_TOKEN environment variables has been deprecated and will be removed in a release after 2024-12-01.
state string	Create or remove the subnet. Choices: "present" ← (default) "absent"
tags aliases: resource_tags dictionary	A dictionary representing the tags to be applied to the resource. If the tags parameter is not set then tags will not be modified.
validate_certs boolean	When set to false, SSL certificates will not be validated for communication with the AWS APIs. Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead. Choices: false true ← (default)
vpc_id string / required	-”VPC ID of the VPC in which to create or delete the subnet.
wait boolean	Whether to wait for changes to complete. Choices: false true ← (default)
wait_timeout integer	Number of seconds to wait for changes to complete Ignored unless wait=true. Default: 300

Notes

Note

• Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.

• The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
