  title: Oracle OCI Create Custom Image from Instance
  summary: Verify an instance is stopped, capture a custom image from it, then poll until the image is available.
  description: >-
    Captures a reusable boot image from an existing compute instance. The
    workflow reads the instance and branches on its lifecycle state: image
    capture requires the instance to be STOPPED. When stopped it creates the
    image from the instance and then polls getImage until the image leaves the
    PROVISIONING state and becomes AVAILABLE. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.

  summary: Capture a custom image from a stopped instance and wait for it to provision.
  description: >-
    Confirms the source instance is STOPPED, creates a custom image from it, and
    polls the image lifecycle state until it is AVAILABLE.
