        # ==== Options
        # * ApplicationName<~String>: If specified, AWS Elastic Beanstalk restricts the returned descriptions
        #     to include only those that are associated with this application.
        # * CNAMEPrefix<~String>: If specified, the environment attempts to use this value as the prefix for the CNAME.
        #     If not specified, the environment uses the environment name.
        # * Description<~String>: Describes this environment.
        # * EnvironmentName<~String>: A unique name for the deployment environment. Used in the application URL.
        # * OptionSettings<~Array>: If specified, AWS Elastic Beanstalk sets the specified configuration options to
        #     the requested value in the configuration set for the new environment. These override the values obtained
        #     from the solution stack or the configuration template.
        # * OptionsToRemove<~Array>: A list of custom user-defined configuration options to remove from the
        #     configuration set for this new environment.
        # * SolutionStackName<~String>: This is an alternative to specifying a configuration name. If specified,
        #     AWS Elastic Beanstalk sets the configuration values to the default values associated with the
        #     specified solution stack.
        # * TemplateName<~String>: The name of the configuration template to use in deployment. If no configuration
        #     template is found with this name, AWS Elastic Beanstalk returns an InvalidParameterValue error.
        # * VersionLabel<~String>: The name of the application version to deploy.
        #
