Kops Releases & Versioning ¶
kops is intended to be backward compatible. It is always recommended to use 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 a period of time.
One exception, in regard to compatibility, kops supports the equivalent Kubernetes minor release number. A minor version is the second digit in the release number. kops version 1.13.0 has a minor version of 13. The numbering follows the semantic versioning specification, MAJOR.MINOR.PATCH.
For example, kops 1.12.0 does not support Kubernetes 1.13.0, but kops 1.13.0 supports Kubernetes 1.12.2 and previous Kubernetes versions. Only when the kops minor version matches the Kubernetes minor version does kops officially support the Kubernetes release. kops does not stop a user from installing mismatching versions of K8s, but Kubernetes releases always require kops to install specific versions of components like docker, that tested against the particular Kubernetes version.
Compatibility Matrix ¶
| kops version | k8s 1.11.x | k8s 1.12.x | k8s 1.13.x | k8s 1.14.x | k8s 1.15.x |
|---|---|---|---|---|---|
| 1.15.0 | ✔ | ✔ | ✔ | ✔ | ✔ |
| 1.14.x | ✔ | ✔ | ✔ | ✔ | ⚫ |
| 1.13.x | ✔ | ✔ | ✔ | ⚫ | ⚫ |
| ✔ | ✔ | ⚫ | ⚫ | ⚫ | |
| ✔ | ⚫ | ⚫ | ⚫ | ⚫ |
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 who are crossed out should work but we suggest should 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.
