Recent stable Kubernetes version
K8up supports legacy Kubernetes clusters such as OpenShift
3.11 (Kubernetes 1.11) as long VSHN (the company behind K8up) operates OpenShift
3.11 with K8up installed.
However, some new features are not supported on Kubernetes <
1.16, e.g. High Availability with Leader election.
See the Repository which upstream Kubernetes version is supported.
