RegisterImage

Registers an AMI. When you're creating an AMI, this is the final step you must complete before you can launch an instance from the AMI. For more information about creating AMIs, see Create your own AMI in the Amazon Elastic Compute Cloud User Guide.

Note

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don't have to register the AMI yourself. We recommend that you always use CreateImage unless you have a specific reason to use RegisterImage.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

Register a snapshot of a root device volume

You can use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. You specify the snapshot using a block device mapping. You can't set the encryption state of the volume using the block device mapping. If the snapshot is encrypted, or encryption by default is enabled, the root volume of an instance launched from the AMI is encrypted.

For more information, see Create a Linux AMI from a snapshot and Use encryption with Amazon EBS-backed AMIs in the Amazon Elastic Compute Cloud User Guide.

AWS Marketplace product codes

If any snapshots have AWS Marketplace product codes, they are copied to the new AMI.

Windows and some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the Amazon EC2 billing product code associated with an AMI to verify the subscription status for package updates. To create a new AMI for operating systems that require a billing product code, instead of registering the AMI, do the following to preserve the billing product code association:

Launch an instance from an existing AMI with that billing product code.
Customize the instance.
Create an AMI from the instance using CreateImage.

If you purchase a Reserved Instance to apply to an On-Demand Instance that was launched from an AMI with a billing product code, make sure that the Reserved Instance has the matching billing product code. If you purchase a Reserved Instance without the matching billing product code, the Reserved Instance will not be applied to the On-Demand Instance. For information about how to obtain the platform details and billing information of an AMI, see Understand AMI billing information in the Amazon EC2 User Guide.

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.

Architecture

The architecture of the AMI.

Default: For Amazon EBS-backed AMIs, i386. For instance store-backed AMIs, the architecture specified in the manifest file.

Type: String

Valid Values: i386 | x86_64 | arm64 | x86_64_mac | arm64_mac

Required: No

BillingProduct.N

The billing product codes. Your account must be authorized to specify billing product codes.

If your account is not authorized to specify billing product codes, you can publish AMIs that include billable software and list them on the AWS Marketplace. You must first register as a seller on the AWS Marketplace. For more information, see Getting started as a seller and AMI-based products in the AWS Marketplace Seller Guide.

Type: Array of strings

Required: No

BlockDeviceMapping.N

The block device mapping entries.

If you specify an Amazon EBS volume using the ID of an Amazon EBS snapshot, you can't specify the encryption state of the volume.

If you create an AMI on an Outpost, then all backing snapshots must be on the same Outpost or in the Region of that Outpost. AMIs on an Outpost that include local snapshots can be used to launch instances on the same Outpost only. For more information, Amazon EBS local snapshots on Outposts in the Amazon EC2 User Guide.

Type: Array of BlockDeviceMapping objects

Required: No

BootMode

The boot mode of the AMI. A value of uefi-preferred indicates that the AMI supports both UEFI and Legacy BIOS.

Note

The operating system contained in the AMI must be configured to support the specified boot mode.

For more information, see Boot modes in the Amazon EC2 User Guide.

Type: String

Valid Values: legacy-bios | uefi | uefi-preferred

Required: No

Description

A description for your AMI.

Type: String

Required: No

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

EnaSupport

Set to true to enable enhanced networking with ENA for the AMI and any instances that you launch from the AMI.

This option is supported only for HVM AMIs. Specifying this option with a PV AMI can make instances launched from the AMI unreachable.

Type: Boolean

Required: No

ImageLocation

The full path to your AMI manifest in Amazon S3 storage. The specified bucket must have the aws-exec-read canned access control list (ACL) to ensure that it can be accessed by Amazon EC2. For more information, see Canned ACLs in the Amazon S3 Service Developer Guide.

Type: String

Required: No

ImdsSupport

Set to v2.0 to indicate 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.

Note

If you set the value to v2.0, make sure that your AMI software can support IMDSv2.

Type: String

Valid Values: v2.0

Required: No

KernelId

The ID of the kernel.

Type: String

Required: No

Name

A name for your AMI.

Constraints: 3-128 alphanumeric characters, parentheses (()), square brackets ([]), spaces ( ), periods (.), slashes (/), dashes (-), single quotes ('), at-signs (@), or underscores(_)

Type: String

Required: Yes

RamdiskId

The ID of the RAM disk.

Type: String

Required: No

RootDeviceName

The device name of the root device volume (for example, /dev/sda1).

Type: String

Required: No

SriovNetSupport

Set to simple to enable enhanced networking with the Intel 82599 Virtual Function interface for the AMI and any instances that you launch from the AMI.

There is no way to disable sriovNetSupport at this time.

This option is supported only for HVM AMIs. Specifying this option with a PV AMI can make instances launched from the AMI unreachable.

Type: String

Required: No

TpmSupport

Set to v2.0 to enable Trusted Platform Module (TPM) support. For more information, see NitroTPM in the Amazon EC2 User Guide.

Type: String

Valid Values: v2.0

Required: No

UefiData

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: String

Length Constraints: Minimum length of 0. Maximum length of 64000.

Required: No

VirtualizationType

The type of virtualization (hvm | paravirtual).

Default: paravirtual

Type: String

Required: No
