How would you answer an interview scenario involving minimal container images in Container Security?
For an interview scenario involving minimal container images, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Minimal images contain only the runtime components needed by an application. In this scenario, a production image contains the entire SDK and build toolchain. Explain how you would redesign the Dockerfile. For production, use multi-stage builds, minimal trusted bases, pinned versions, and retain only required runtime files. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
