The docs are a little sparse but reading between the lines it&#x27;s a set of tools for configuring k8s clusters at a higher level of abstraction than gcloud and kubectl. If you&#x27;ve built out automation to deploy k8s services then you know that there is still quite a bit of manual configuration needed to define the clusters, repl controllers, services, ingress, persistent disks, etc. If you wanted to build a PAAS on top of k8s then you&#x27;d begin pretty much as these guys have, I think.
