Synopsis

Manage role/user access to a KMS key. Not designed for encrypting/decrypting.

Requirements

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

python >= 2.6
boto

Parameters

Parameter	Choices/Defaults	Comments
alias -		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 aws_kms_facts to find key ids. Required if key_id is not given. 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. aliases: key_alias
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
clean_invalid_entries boolean	Choices: no yes ←	If adding/removing a role and invalid grantees are found, remove them. These entries will cause an update to fail in all known cases. Only cleans if changes are being made.
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.
description - added in 2.8		A description of the CMK. Use a description that helps you decide whether the CMK is appropriate for a task.
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.
enabled boolean added in 2.8	Choices: no yes ←	Whether or not a key is enabled
grant_types -		List of grants to give to user/role. Likely "role,role grant" or "role,role grant,admin". Required when `mode=grant`.
grants - added in 2.8		A list of grants to apply to the key. Each item must contain grantee_principal. Each item can optionally contain retiring_principal, operations, constraints, name. Valid operations are `Decrypt`, `Encrypt`, `GenerateDataKey`, `GenerateDataKeyWithoutPlaintext`, `ReEncryptFrom`, `ReEncryptTo`, `CreateGrant`, `RetireGrant`, `DescribeKey`, `Verify` and `Sign` Constraints is a dict containing `encryption_context_subset` or `encryption_context_equals`, either or both being a dict specifying an encryption context match. See https://docs.aws.amazon.com/kms/latest/APIReference/API_GrantConstraints.html grantee_principal and retiring_principal must be ARNs
key_id -		Key ID or ARN of the key. One of `alias` or `key_id` are required. aliases: key_arn
mode -	Choices: grant ← deny	Grant or deny access.
policy - added in 2.8		policy to apply to the KMS key See https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html
profile string		Uses a boto profile. Only works with boto >= 2.24.0.
purge_grants boolean added in 2.8	Choices: no ← yes	Whether the grants argument should cause grants not in the list to be removed
purge_tags boolean added in 2.8	Choices: no ← yes	Whether the tags argument should cause tags not in the list to be removed
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
role_arn -		ARN of role to allow/deny access. One of `role_name` or `role_arn` are required.
role_name -		Role to allow/deny access. One of `role_name` or `role_arn` are required.
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 - added in 2.8	Choices: present ← absent	Whether a key should be present or absent. Note that making an existing key absent only schedules a key for deletion. Passing a key that is scheduled for deletion with state present will cancel key deletion.
tags - added in 2.8		A dictionary of tags to apply to a key.
validate_certs boolean	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

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
