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.
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.
compatible_architectures list / elements=string	A list of compatible instruction set architectures. For example, x86_64. Mutually exclusive with `version`.
compatible_runtimes list / elements=string	A list of compatible function runtimes. Ignored when `state=absent`. Mutually exclusive with `version`.
content dictionary	The function layer archive. Required when `state=present`. Ignored when `state=absent`. Mutually exclusive with o(version).
s3_bucket string	The Amazon S3 bucket of the layer archive.
s3_key string	The Amazon S3 key of the layer archive.
s3_object_version string	For versioned objects, the version of the layer archive object to use.
zip_file path	Path to the base64-encoded file of the layer archive.
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`
description string	The description of the version. Ignored when `state=absent`. Mutually exclusive with `version`.
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.

name aliases: layer_name string / required	The name or Amazon Resource Name (ARN) of the Lambda layer.
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.
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.

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	Determines if an Lambda layer should be created, or deleted. When set to `present`, an Lambda layer version will be created. If set to `absent`, an existing Lambda layer version will be deleted. Choices: `"absent"` `"present"` ← (default)
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)
version integer	The version number of the layer to delete. Set to `-1` to delete all versions for the specified layer name. Required when `state=absent`. Ignored when `state=present`. Mutually exclusive with `description`, `content`, `compatible_runtimes`, `license_info`, `compatible_architectures`.

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.
