“You are now Certified Kubernetes.” With this comment, Docker for Windows and Docker for Mac passed the Kubernetes conformance tests. Kubernetes has been available in Docker for Mac and Docker for Windows since January, having first being announced at DockerCon EU last year. But why is this important to the many of you who are using Docker for Windows and Docker for Mac?
Kubernetes is designed to be a platform that others can build upon. As with any similar project, the risk is that different distributions vary enough that applications aren’t really portable. The Kubernetes project has always been aware of that risk – and this led directly to forming the Conformance Working Group. The group owns a test suite that anyone distributing Kubernetes can run, and submit the results for to attain official certification. This test suite checks that Kubernetes behaves like, well, Kubernetes; that the various APIs are exposed correctly and that applications built using the core APIs will run successfully. In fact, our enterprise container platform, Docker Enterprise Edition, achieved certification using the same test suite You can find more about the test suite at https://github.com/cncf/k8s-conformance.
