[All AWS-SysOps Questions]

A user has launched an EC2 instance from an instance store backed AMI. The user has attached an additional instance store volume to the instance. The user wants to create an AMI from the running instance. Will the AMI have the additional instance store volume data?

  • A. Yes, the block device mapping will have information about the additional instance store volume
  • B. No, since the instance store backed AMI can have only the root volume bundled
  • C. It is not possible to attach an additional instance store volume to the existing instance store backed AMI instance
  • D. No, since this is ephemeral storage it will not be a part of the AMI

Suggested Answer: A 🗳️
When the user has launched an EC2 instance from an instance store backed AMI and added an instance store volume to the instance in addition to the root device volume, the block device mapping for the new AMI contains the information for these volumes as well. In addition, the block device mappings for the instances those are launched from the new AMI will automatically contain information for these volumes.

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.
