                    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 | |

Notes¶
Note
- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URLorEC2_URL,AWS_ACCESS_KEY_IDorAWS_ACCESS_KEYorEC2_ACCESS_KEY,AWS_SECRET_ACCESS_KEYorAWS_SECRET_KEYorEC2_SECRET_KEY,AWS_SECURITY_TOKENorEC2_SECURITY_TOKEN,AWS_REGIONorEC2_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_REGIONor- EC2_REGIONcan be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
