Docker Interview Deep Dive: Reasoning Through Real Scenarios
The Docker questions that separate someone who memorized definitions from someone who has actually debugged a container at 2am -- walked through with the reasoning an interviewer is actually listening for.
Learning objectives
- Explain the image-versus-container distinction in terms an interviewer can tell you've actually worked with, not just defined
- Diagnose a container consuming unexpected memory using the right sequence of checks
- Reason correctly about CMD vs ENTRYPOINT interactions and justify an image-size reduction strategy
- Explain what happens to a container when its main process exits and why that shapes how containers should be designed
