Synopsis

Requirements

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

Parameters

Parameter

Comments

aws_access_key

aliases: ec2_access_key, 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.

If profile is set this parameter is ignored.

Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aws_ca_bundle

path

The location of a CA Bundle to use when validating SSL certificates.

Not used by boto 2 based modules.

Note: The CA Bundle is read ‘module’ side and may need to be explicitly copied from the controller if not run locally.

aws_config

dictionary

A dictionary to modify the botocore configuration.

Parameters can be found at https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.

Only the ‘user_agent’ key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.

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_PROFILE or AWS_DEFAULT_PROFILE, 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, AWS_CA_BUNDLE

  • When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.

  • Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.

  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
