Maintaining a CNCF project involves managing critical infrastructure at scale, including publishing trusted images and ensuring dependencies remain secure. To support these efforts, the CNCF-Docker partnership (announced in 2025) enables CNCF projects to access Docker's Sponsored Open Source (DSOS) program. DSOS provides essential infrastructure and security tools specifically for non-commercial open-source maintainers.

Here is what you need to know about the benefits, eligibility, and how to apply.

Key Benefits for Your Project​

Joining the DSOS program offers several high-impact advantages for project maintainership:

  • Unlimited Image Pulls: Removes rate limits for your users on Docker Hub.
  • "Sponsored OSS" Status: Gains a verified badge for greater trust and visibility.
  • Advanced Security: Access to Docker Scout for vulnerability analysis and policy enforcement.
  • Automated Workflows: Streamlined image builds directly from your source code.
  • Insights: Access to Docker usage metrics and community engagement data.

Important Technical Considerations​

1. Transitioning to an Organization Account​

If your project currently publishes images under a personal Docker ID, you must convert it to an organization account.

  • This conversion is free.
  • A second Docker user account is required to act as the "Owner" of the organization.
  • The email addresses for the organization and the owner account must be the same to ensure proper access control.

2. Paid Subscription Conflict​

DSOS and paid Docker subscriptions are mutually exclusive. If your project currently pays for a subscription, you must transition off that plan before you can join the DSOS program.

How to Apply​

Applications must be submitted via the CNCF ServiceDesk rather than directly to Docker. This workflow ensures the request comes from an official CNCF project and prioritizes the request with Docker.

What happens after approval?​

Once approved, benefits are granted at the project level for one year. Renewals are available as long as the project remains active, non-commercial, and continues to meet the eligibility criteria.
