kubeconform

A fast Kubernetes manifests validator with support for custom resources. It is inspired by, contains code from and is designed to stay close to Kubeval, but with the following improvements: * high performance: will validate & download manifests over multiple routines, caching downloaded files in memory * configurable list of remote, or local schemas locations, enabling validating Kubernetes custom resources (CRDs) and offline validation capabilities * uses by default a self-updating fork of the schemas registry maintained by the kubernetes-json-schema project - which guarantees up-to-date schemas for all recent versions of Kubernetes.
