In the S2I build command, what does the option --as-dockerfile <destination>/Dockerfile do?

• A. Outputs a Dockerfile to the specified path without building
• B. Builds a Dockerfile and then builds the image
• C. Writes build logs to the Dockerfile
• D. Converts Dockerfile to an image with the given tag

Answer: (A)

This option focuses on exposing the exact Dockerfile S2I would use for the build. By specifying a destination like <destination>/Dockerfile, S2I writes that Dockerfile to the given path instead of performing the image build. It’s a dry-run view of the steps, useful for inspecting or reusing the build recipe. It does not build an image, nor does it log to the Dockerfile or convert a Dockerfile into an image.
