Creating an Instance Store-Backed Linux AMI
To create an instance store-backed Linux AMI, start from an instance that you've launched from an existing instance store-backed Linux AMI. After you've customized the instance to suit your needs, bundle the volume and register a new AMI, which you can use to launch new instances with these customizations.
If you need to create an instance store-backed Windows AMI, see Creating an Instance Store-Backed Windows AMI in the Amazon EC2 User Guide for Windows Instances.
The AMI creation process is different for instance store-backed AMIs. For more information about the differences between Amazon EBS-backed and instance store-backed instances, and how to determine the root device type for your instance, see Storage for the Root Device. If you need to create an Amazon EBS-backed Linux AMI, see Creating an Amazon EBS-Backed Linux AMI.
Overview of the Creation Process for Instance Store-Backed AMIs
The following diagram summarizes the process of creating an AMI from an instance store-backed instance.
First, launch an instance from an AMI that's similar to the AMI that you'd like to
create. You can connect to your instance and customize it. When the instance is set up
the way you want it, you can bundle it. It takes several minutes for the bundling
process to complete. After the process completes, you have a bundle, which consists of
an image manifest (
image.manifest.xml) and files
image.part.xx) that contain a template
for the root volume. Next you upload the bundle to your Amazon S3 bucket and then register
When you launch an instance using the new AMI, we create the root volume for the instance using the bundle that you uploaded to Amazon S3. The storage space used by the bundle in Amazon S3 incurs charges to your account until you delete it. For more information, see Deregistering Your AMI.
If you add instance store volumes to your instance in addition to the root device volume, the block device mapping for the new AMI contains information for these volumes, and the block device mappings for instances that you launch from the new AMI automatically contain information for these volumes. For more information, see Block Device Mapping.
Before you can create an AMI, you must complete the following tasks:
Install the AMI tools. For more information, see Setting Up the AMI Tools.
Install the AWS CLI. For more information, see Getting Set Up with the AWS Command Line Interface.
Ensure that you have an Amazon S3 bucket for the bundle. To create an Amazon S3 bucket, open the Amazon S3 console and click Create Bucket. Alternatively, you can use the AWS CLI mb command.
Ensure that you have your AWS account ID. For more information, see AWS Account Identifiers in the AWS General Reference.
Ensure that you have your access key ID and secret access key. For more information, see Access Keys in the AWS General Reference.
Ensure that you have an X.509 certificate and corresponding private key.
If you need to create an X.509 certificate, see Managing Signing Certificates. The X.509 certificate and private key are used to encrypt and decrypt your AMI.
