Kubespray is fine if you can spare hours of Dev time. Where I used to work I wasn't involved directly with maintaining the k8s cluster using kubespray, but from the daily meetings it was clear that it is no easy task. Sure it helps with deploying a serviceable production cluster, but when you start throwing at it things like disaster recovery, the automation scripts can grow quite large and complex, even leveraging kubespray. If you can, use a managed service like gks.
