===============================================
Kubernetes and OpenShift version support matrix
===============================================
This document maintains updated documentation about what Kubernetes and
OpenShift versions are supported at each Kuryr-Kubernetes release.
.. note::
In general Kuryr should work fine with older versions of Kubernetes and
OpenShift as well as it only depends from the APIs that are quite stable
in Kubernetes itself. However we try to limit the number of supported
versions, as Kubernetes policy is to only support last 3 minor releases.
.. note::
Kuryr-Kubernetes follows *cycle-with-intermediary* release model and that's
why there are multiple minor releases per single OpenStack release. Going
forward it is possible that Kuryr-Kubernetes will switch to *independent*
release model, that would completely untie it from OpenStack releases. This
is because it seems to be easier to follow Kubernetes releases than
OpenStack releases.
.. warning::
In most cases only the latest supported version is tested in the CI/CD
system.
