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 Creating Your Own AMIs in the Amazon Elastic Compute Cloud User Guide.

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.

You can also use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. You specify the snapshot using the block device mapping. For more information, see Launching a Linux Instance from a Backup in the Amazon Elastic Compute Cloud User Guide.

You can't register an image where a secondary (non-root) snapshot has AWS Marketplace product codes.

Some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the EC2 billing product code associated with an AMI to verify the subscription status for package updates. Creating an AMI from an EBS snapshot does not maintain this billing code, and instances launched from such an AMI are not able to connect to package update infrastructure. If you purchase a Reserved Instance offering for one of these Linux distributions and launch instances using an AMI that does not contain the required billing code, your Reserved Instance is not applied to these instances.

To create an AMI for operating systems that require a billing code, see CreateImage.

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.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to RegisterImageAsync.
