“Security shouldn’t be a premium feature. By making hardened images free, Docker is letting every developer—not just big enterprises—start with a safer foundation. We love seeing tools that reduce noise and toil, and we’re ready to run these secure workloads on Google Cloud from day one.”

Ryan J Salva

Senior Director of Product, Developer Experiences

“At MongoDB, we believe open source plays a central role in how modern software is built, enabling flexibility, choice, and developer productivity. That’s why we’re excited about free Docker Hardened Images for MongoDB. These images provide trusted, ready-to-deploy building blocks on proven Linux foundations such as Alpine and Debian, and with an Apache 2.0 license, they remain fully open source and free for anyone to use. With Docker Hub’s global reach and MongoDB’s commitment to reliability and safety, we are making it easier to build with confidence on a secure and open foundation for the future.”

Jim Scharf

Chief Technology Officer, MongoDB

“Docker’s move to make its hardened images freely available under Apache 2.0 underscores its strong commitment to the open source ecosystem. Many CNCF projects can already be found in the DHI catalog, and giving the broader community access to secure, well-maintained building blocks helps us strengthen the software supply chain together. It’s exciting to see Docker continue to invest in open collaboration and secure container infrastructure.”

Jonathan Bryce

Executive Director, Cloud Native Computing Foundation
