  title: Oracle OCI Select Shape and Image then Launch
  summary: List available shapes, find a matching image, then launch an instance using both.
  description: >-
    Discovers the compute resources available in a compartment and provisions an
    instance from them. The workflow lists the shapes available in the
    availability domain, lists images filtered by operating system, and then
    launches a new instance wired to the first discovered shape and image. This
    chains a discovery pass into a create so callers do not need to know shape or
    image OCIDs in advance. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
