The .s2i/bin directory in a source tree contains what?

• A. Prebuilt application binaries
• B. Docker configuration files
• C. S2I scripts used to customize the build process
• D. Build manifests

Answer: (C)

The important idea here is that this directory holds the S2I scripts that drive how the source is turned into an image. The .s2i/bin directory contains the scripts used by Source-to-Image to customize and control the build process for an application, such as assembling dependencies, compiling or configuring the app, and defining how the container should start. These scripts (often including assemble, run, and sometimes detect or save-artifacts) live in the source tree so you can tailor the image behavior for your project. They are not prebuilt binaries, Docker configuration files, or build manifests, which is why they belong in this location to influence the build steps themselves.
