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.

Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.

action_prefix

string

This parameter can be used to filter the results of the operation to only those alarms that use a certain alarm action.

alarm_name_prefix

string

An alarm name prefix to retrieve information about alarms that have names that start with this prefix.

Can not be used with alarm_names.

alarm_names

list / elements=string

The name of the metric.

alarm_type

string

Specify this to return metric alarms or composite alarms.

Module is defaulted to return metric alarms but can return composite alarms if alarm_type=CompositeAlarm.

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.
