Container Security — Apps in Boxes, Shipped Safe

A friendly first course on how modern software ships — apps packed into containers — and the six questions that keep the boxes trustworthy: what's in it, where's it from, how fresh, any secrets, how much power, and did it take the road.

What you'll learn

• Explain containers, images, and the yard's road — build, shelve, run — in plain words, and know why an orchestrator is a manager, not an inspector.
• Read scan reports calmly (inheritance from bases, severity ordering, the boring fresh-parts-and-rebuild fix) and apply the source rule: official and verified shelves, names checked letter by letter, everything unusual routed.
• Keep boxes fresh by rhythm and never let secrets ride: store-kept, run-time delivered, pointers not values, and report-and-rotate in minutes when one slips.
• Ship least-privilege boxes on shared ground — non-root, minimal, fenced, defended asks — and mind the yard together: strengthen the gates, ask the platform team early, and teach the six-question card forward.
