  title: Amazon EC2 Image Builder Decommission Pipeline Stack
  summary: Read an image pipeline, delete it, then delete the image recipe and infrastructure configuration it used.
  description: >-
    Tears down a pipeline stack in dependency-safe order. The workflow first
    reads the image pipeline to capture the recipe and infrastructure
    configuration ARNs it references, then deletes the pipeline so it no longer
    holds those resources, and finally deletes the image recipe and the
    infrastructure configuration. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
