CNCF Expands Infrastructure Support for Project Maintainers Through Partnership with Docker

About Cloud Native Computing Foundation Media Contact CNCF projects gain access to trusted container distribution, enhanced security tooling, and usage insights via Docker’s Sponsored Open Source Program SAN FRANCISCO, CA – September 18, 2025 – The Cloud Native Computing Foundation ® (CNCF®), which builds sustainable ecosystems for cloud native software, today announced a new partnership with Docker, Inc. ®, a provider of cloud-native application and AI-native application development solutions and infrastructure, to expand secure, scalable support for CNCF-hosted projects. Through this collaboration all CNCF projects will gain direct access to Docker’s Sponsored Open Source (DSOS) program which helps open source communities grow and succeed by unlocking premium registry, security, and support services. “Docker was a founding member of CNCF, and we’ve maintained a long-term open collaboration over the past decade,” said Chris Aniszczyk, CTO, CNCF. “This partnership marks a step forward for CNCF projects and we’re glad to work together to further secure the open source supply chain. ” A Strategic Collaboration for the Ecosystem With DSOS access, CNCF projects will now benefit from: Unlimited image pulls from Docker Hub Sponsored OSS status for greater trust and visibility Access to Docker Scout for vulnerability analysis and policy enforcement Automated image builds from source Docker usage metrics and engagement insights Streamlined support through open source channels Docker Hub, the world’s largest registry for discovering, sharing, and storing container images, supports over 22 billion image downloads each month and hosts more than 14 million images. This partnership reflects CNCF’s commitment to supporting widely used infrastructure across the cloud native ecosystem, recognizing Docker’s role in both open source and enterprise workflows. For project maintainers, the partnership provides secure, scalable infrastructure tailored to the realities of running production-grade open source projects. For users, it ensures reliable and trustworthy access to the cloud native tools they depend on. “Docker’s mission has always been to empower developers, and we know that trust is earned through consistency, openness, and listening,” said Michael Donovan, VP of Products at Docker. “This partnership with CNCF reflects a broader commitment to the open source community by helping maintainers grow their projects, reach more developers through Docker Hub, and deliver value to their communities faster with improved tools, automation, and support. ” A Commitment to Secure Open Source Infrastructure This partnership also highlights a shared commitment to strengthening the open source software supply chain.
