Container Images: Slim Without Breaking Debuggability
By Na-ri Jung · 2025-07-21
Students often chase minimal image size and lose shell access mentors need during labs. We compare three strategies: multi-stage builds, slim bases with busybox sidecars, and distroless with ephemeral debug pods.
Security scanning should run on the final promoted tag, not intermediate layers students discard. Integrate scans before registry promotion, not after deploy.
For local Jinju workshops, we provide pre-built debug variants students can swap in during incidents, then remove before production promotion.
Capstone reviewers look for an explicit debug policy in your README. Omit it and expect questions during defense.
