Contribution Guides to the CNCF Ecosystem

Welcome! Are you interested in contributing to one of CNCF hosted projects? This repository should help you. It contains information and guidelines about contributions to CNCF projects.

CNCF offers multiple ways to start contributing to the CNCF ecosystem, including either foundation-wide and project-wide opportunities.


The CNCF TOC is the technical governing body of the CNCF Foundation. The detailed information on CNCF TOC, including its duties and responsibilities, together with the information on collaboration is listed on CNCF TOC repo.

Technical Advisory Groups

CNCF TAGs oversee and coordinate the interests pertaining to a logical area of needs of end users and/or projects. More details about the CNCF TAGs is available here.

Note: CNCF TAGs were previously named Special Interest Groups (SIGs). Renaming SIGs was discussed in this GitHub Issue.

Working Groups

Working groups (WG’s) are the community-driven groups with the goal of continuous collaboration in the specific areas. CNCF WG’s are created and curated by the CNCF TOC and driven by the community members. CNCF TOC repo provides more details on the purpose and goals of WG’s, together with the list of them.

Community Engagement


Cloud Native Ambassadors (CNAs) are individuals who are passionate about Cloud Native Computing Foundation technology and projects, recognized for their expertise, and willing to help others learn about the framework and community.

Successful ambassadors are people such as bloggers, influencers, evangelists who are already engaged with a CNCF project in some way including contributing to forums, online groups, community events, etc.

Details on the Ambassadors program, and information on how to join CNCF as an Ambassador is available here.


The Cloud Native Computing Foundation supports the worldwide community of the Cloud Native meetups. They are listed on website.

CNCF is currently working on expanding the Cloud Native community around the globe, and we are happy to accept the new meetup communities to join our network, and become one of the official CNCF meetups.

Details on the Meetups program, together with the best practices on running CNCF Meetups is available here.
