Hardened Images: crafted by humans, protected by AI

Docker just wired anAI guardrailstraight into its Hardened Image (DHI) pipeline. It scans upstream diffs, catches regressions before they ship, and stops bad logic in its tracks. Case in point: it flagged a logic bug that slipped past the usual coding copilots. A real fix landed upstream. Win for cu.. read more
