New in community.aws 1.0.0

Synopsis

Requirements

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

  • python >= 3.6

  • boto3 >= 1.18.0

  • botocore >= 1.21.0

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. Prior to release 6.0.0 these environment variables will be ignored if the profile parameter is passed. After release 6.0.0 access_key will always fall back to the environment variables if set.

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.

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.

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

egress

list / elements=list

A list of rules for outgoing traffic. Each rule must be specified as a list. Each rule may contain the rule number (integer 1-32766), protocol (one of [‘tcp’, ‘udp’, ‘icmp’, ‘ipv6-icmp’, ‘-1’, ‘all’]), the rule action (‘allow’ or ‘deny’) the CIDR of the IPv4 or IPv6 network range to allow or deny, the ICMP type (-1 means all types), the ICMP code (-1 means all codes), the last port in the range for TCP or UDP protocols, and the first port in the range for TCP or UDP protocols. See examples.

Default: []

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.

See examples.

Default: []

nacl_id

string

NACL id identifying a network ACL.

One and only one of the name or nacl_id is required.

name

string

Tagged name identifying a network ACL.

One and only one of the name or nacl_id is required.

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. Prior to release 6.0.0 the AWS_PROFILE environment variable will be ignored if any of access_key, secret_key, or session_token are passed. After release 6.0.0 profile will always fall back to the AWS_PROFILE environment variable if set.

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

Must be specified as a list

Each subnet can be specified as subnet ID, or its tagged name.

Default: []

tags

aliases: resource_tags

dictionary

If the tags parameter is not set then tags will not be modified.

validate_certs

boolean

  • false

  • true ← (default)

vpc_id

string

VPC id of the requesting VPC.

Required when state present.

Notes

Note

  • Support for purge_tags was added in release 4.0.0.

  • 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.
