Supply chain attacks cost $60 billion in 2025. Docker just made the solution free. On December 17, Docker released 1,000+ hardened container images under Apache 2.0—previously a paid offering. Independent penetration testing by SRLabs confirmed 95% CVE reduction and found NO root escapes or container breakouts. These images use distroless runtime: no shell, no package manager, no attack surface. We break down how distroless actually works (why removing /bin/sh matters), SLSA Level 3 cryptographic provenance, SBOM/VEX for killing alert fatigue, multi-stage build migration patterns, debugging without a shell (kubectl debug), and how Docker compares to Chainguard Wolfi, Google distroless, and Red Hat UBI.
