  title: Amazon EC2 Clone an Instance via Image
  summary: Create an AMI from a source instance, confirm it, then launch a clone from that AMI.
  description: >-
    Duplicates a running instance through a captured image. The workflow creates
    an AMI from the source instance, confirms the image is available via
    DescribeImages, and launches a new instance from the captured AMI. Every
    step spells out its request inline using the Amazon EC2 query protocol
    (Action and Version parameters) so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Image a source instance and launch a clone from the captured AMI.
  description: >-
    Chains CreateImage, DescribeImages, and RunInstances so a source instance is
    captured into an AMI, the AMI is confirmed, and a clone is launched from it.
