How would you answer an interview scenario involving Docker images?

For an interview scenario involving Docker images, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Docker images are immutable package templates containing application code, runtime, libraries, and filesystem layers. 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.
