/**

 * <p>Describes the specified attribute of the specified instance. You can specify only one
 *             attribute at a time. Valid attribute values are: <code>instanceType</code> |
 *                 <code>kernel</code> | <code>ramdisk</code> | <code>userData</code> |
 *                 <code>disableApiTermination</code> | <code>instanceInitiatedShutdownBehavior</code>
 *             | <code>rootDeviceName</code> | <code>blockDeviceMapping</code> |
 *                 <code>productCodes</code> | <code>sourceDestCheck</code> | <code>groupSet</code> |
 *                 <code>ebsOptimized</code> | <code>sriovNetSupport</code>
 *          </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript

 * // const { EC2Client, DescribeInstanceAttributeCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);

 *   DryRun: true || false,
 *   InstanceId: "STRING_VALUE", // required
