  title: Amazon EC2 Image Builder Cancel Running Image Build
  summary: Start an image build, inspect its state, and cancel it while it is still in a non-terminal state.
  description: >-
    Provides a controlled way to abort an image build that is still running. The
    workflow creates an image, reads its current state, and branches: when the
    image is still in a non-terminal state such as building or testing it issues
    a cancel request and re-reads the image to confirm cancellation, and when
    the image has already reached a terminal state it ends without cancelling.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.

  summary: Create an image and cancel it if it is still building, then confirm the cancellation.
  description: >-
    Builds an image, checks its state, and conditionally cancels the build while
    it is non-terminal, finally re-reading the image to confirm the result.
