How would you answer an interview scenario involving Docker security?
For an interview scenario involving Docker security, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Docker security includes trusted images, least privilege, runtime isolation, secret handling, patching, and supply-chain controls. In this scenario, a team wants to run all production containers with --privileged to solve permission problems. Explain why that is risky and what alternatives you would investigate. 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.
