amazon.aws.kms_key module – Perform various KMS key management tasks

Note

This module is part of the amazon.aws collection (version 5.2.0).

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. You need further requirements to be able to use this module, see Requirements for details.

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

New in amazon.aws 5.0.0

Synopsis

  • Manage role/user access to a KMS key.

  • Not designed for encrypting/decrypting.

  • Prior to release 5.0.0 this module was called community.aws.aws_kms. The usage did not change.

  • This module was originally added to community.aws in release 1.0.0.

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.

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.

alias

aliases: key_alias

string

An alias for a key.

For safety, even though KMS does not require keys to have an alias, this module expects all new keys to be given an alias to make them easier to manage. Existing keys without an alias may be referred to by key_id. Use amazon.aws.kms_key_info to find key ids.

Note that passing a key_id and alias will only cause a new alias to be added, an alias will never be renamed.

The alias/ prefix is optional.

Required if key_id is not given.

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

description

string

A description of the CMK.

Use a description that helps you decide whether the CMK is appropriate for a task.

enable_key_rotation

boolean

Whether the key should be automatically rotated every year.

Choices:

  • false

  • true

enabled

boolean

Whether or not a key is enabled.

Choices:

  • false

  • true ← (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.

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.

Notes

Note

  • There are known inconsistencies in the amount of time required for updates of KMS keys to be fully reflected on AWS. This can cause issues when running duplicate tasks in succession or using the amazon.aws.kms_key_info module to fetch key metadata shortly after modifying keys. For this reason, it is recommended to use the return data from this module (amazon.aws.kms_key) to fetch a key’s metadata.

  • 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.
