Describes the specified attribute of the specified AMI. You can specify only one attribute at a time.


The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.


The AMI attribute.

Note: The blockDeviceMapping attribute is deprecated. Using this attribute returns the Client.AuthFailure error. To get information about the block device mappings for an AMI, use the DescribeImages action.

Type: String

Valid Values: description | kernel | ramdisk | launchPermission | productCodes | blockDeviceMapping | sriovNetSupport | bootMode | tpmSupport | uefiData | lastLaunchedTime | imdsSupport | deregistrationProtection

Required: Yes

If v2.0, it indicates that IMDSv2 is specified in the AMI. Instances launched from this AMI will have HttpTokens automatically set to required so that, by default, the instance requires that IMDSv2 is used when requesting instance metadata. In addition, HttpPutResponseHopLimit is set to 2. For more information, see Configure the AMI in the Amazon EC2 User Guide.

Type: AttributeValue object


The kernel ID.

Type: AttributeValue object


The date and time, in ISO 8601 date-time format, when the AMI was last used to launch an EC2 instance. When the AMI is used to launch an instance, there is a 24-hour delay before that usage is reported.


lastLaunchedTime data is available starting April 2017.

Type: AttributeValue object


The launch permissions.

Type: Array of LaunchPermission objects


The product codes.

Type: Array of ProductCode objects


The RAM disk ID.

Type: AttributeValue object


The ID of the request.

Base64 representation of the non-volatile UEFI variable store. To retrieve the UEFI data, use the GetInstanceUefiData command. You can inspect and modify the UEFI data by using the python-uefivars tool on GitHub. For more information, see UEFI Secure Boot in the Amazon EC2 User Guide.

Type: AttributeValue object
