Docker Hardened Images: Secure, Minimal, and Ready for Production

From the very beginning, Docker has been dedicated to empowering developers to build, share, and run applications efficiently and securely. With over 14 million container images and more than 11 billion monthly pulls, Docker Hub stands as a global cornerstone in modern software delivery. This reach gives us unmatched insight into the evolving security landscape and the challenges developers face daily.

Today, we’re doubling down on our commitment to developer-first supply chain security.

Announcing Docker Hardened Images (DHI)

Docker Hardened Images are a new class of secure-by-default containers — engineered specifically for modern production environments. Unlike generic minimal images, DHI images offer:

• Up to 95% reduction in attack surface
• Zero known CVEs, maintained and patched continuously.
• Support for popular distros like Alpine and Debian
• Seamless integration with your existing workflows and CI/CD tools

From the OS layer up, these images are curated, stripped of risk-prone components, and hardened to deliver the strongest security posture without breaking compatibility.
