kOps Releases & Versioning

kOps intends to be backward compatible. It is always recommended using the latest version of kOps with whatever version of Kubernetes you are using. We suggest kOps users run one of the 3 minor versions Kubernetes is supporting however we do our best to support previous releases for some period.

kOps does not, however, support Kubernetes releases that have either a greater major release number or greater minor release number than it. (The numbers before the first and second dots are the major and minor release numbers, respectively.) For example, kOps 1.20.0 does not support Kubernetes 1.21.0, but does support Kubernetes 1.20.5, 1.19.2, and several previous Kubernetes versions.

Compatibility Matrix

Use the latest version of kOps for all releases of Kubernetes, with the caveat that higher versions of Kubernetes are not officially supported by kOps. Releases which are crossed out should work, but are unlikely to get security or other fixes. We suggest they be upgraded soon.

Release Schedule

This project does not follow the Kubernetes release schedule. kOps aims to provide a reliable installation experience for Kubernetes, and typically releases about a month after the corresponding Kubernetes release. This time allows for the Kubernetes project to resolve any issues introduced by the new version and ensures that we can support the latest features. kOps will release alpha and beta pre-releases for people that are eager to try the latest Kubernetes release. Please only use pre-GA kOps releases in environments that can tolerate the quirks of new releases, and please do report any issues encountered.
