If an instance has an EBS root device, you can easily create an AMI from it.
To create an image from an Amazon EBS-backed instance
- Right-click an instance that shows “ebs” in theÂ Root Device field and clickÂ Create Image (EBS AMI).
TheÂ Create Image dialog box appears.
- Enter a name for the image (required) and a description (optional).
- ClickÂ Create this Image.
Amazon EC2 begins creating a snapshot and an image. You will not be able to delete this snapshot without deleting the AMI as well.
