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.
