Supported Kubernetes Versions

Tim Van Steenburgh edited this page Aug 21, 2018 · 9 revisions

CDK officially supports the most recent three (3) minor releases of Kubernetes. For example, at the time of this writing, the latest stable release of Kubernetes is 1.11.2, which means that CDK supports versions 1.11.x, 1.10.x, and 1.9.x.

Getting Version Info

To check which versions are available, use the snap info command as seen below. Keep in mind that although snap info enumerates all available versions, only the latest three stable versions are officially supported. In the output below, note that 1.12 and 1.13 are not officially supported because they do not have a stable release, and versions older than 1.9.x are not supported because they are not one of the most recent three stable versions.
