Dev pipeline builds an image, staging pipeline builds an image, production pipeline builds an image. The code is the same. The Dockerfile is the same. The result is theoretically the same. But you spent three build cycles to get there, and you have no actual guarantee that what you tested in dev is what you shipped to prod.
