Docker Open Sources 1000+ Hardened Container Images Under Apache 2.0
OpenSource For U, December 11,2025
Docker has open sourced its most security-critical container infrastructure, making over 1000 hardened images free under Apache 2.0 to turn secure-by-default containers into an industry-wide baseline rather than a paid feature.
Docker has made more than 1000 Docker Hardened Images (DHI) fully open source and available for free, marking a decisive shift from a commercial-only model to an open standard for container security. Released under the Apache 2.0 license, the images are now subscription-free and accessible to all 26 million-plus developers in the global container ecosystem.
Announcing the move, Docker said: 'Today, we are establishing a new industry standard by making DHI freely available and open source to everyone who builds software. All 26 Million+ developers in the container ecosystem.'
