How would you answer an interview scenario involving Docker Compose?

For an interview scenario involving Docker Compose, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Docker Compose defines multi-container applications, networks, volumes, and environment configuration in a declarative YAML file. 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.
