For organizations using Kubernetes, conformance enables interoperability from one Kubernetes installation to the next. It allows them the flexibility to choose between vendors.

CNCF runs the Certified Kubernetes Conformance Program. Most of the world’s leading enterprise software vendors and cloud computing providers have Certified Kubernetes offerings.

There are over 90 Certified Kubernetes offerings. All vendors are invited to submit conformance testing results for review and certification by the CNCF. If your company provides software based on Kubernetes, we encourage you to get certified today.

Certified Kubernetes Conformance Program benefits

1. Consistency: Users want consistency when interacting with any installation of Kubernetes.
2. Timely updates: To remain certified, vendors need to provide the latest version of Kubernetes yearly or more frequently, so you can be sure that you’ll always have access to the latest features the community has been working hard to deliver.
3. Confirmability: Any end user can confirm that their distribution or platform remains conformant by running the identical open source conformance application (Sonobuoy) that was used to certify.
