        # ==== Parameters
        # * lb_name<~String> - Name of the ELB
        # * health_check<~Hash> - A hash of parameters describing the health check
        #   * 'HealthyThreshold'<~Integer> - Specifies the number of consecutive
        #     health probe successes required before moving the instance to the Healthy state.
        #   * 'Interval'<~Integer> - Specifies the approximate interval, in seconds,
        #     between health checks of an individual instance.
        #   * 'Target'<~String> - Specifies the instance being checked.

        #   * 'Timeout'<~Integer> - Specifies the amount of time, in seconds,
        #   during which no response means a failed health probe.
        #   * 'UnhealthyThreshold'<~Integer> - Specifies the number of consecutive
