Validate your Kubernetes configuration files, supports multiple Kubernetes versions

Kubeval

kubeval is a tool for validating a Kubernetes YAML or JSON configuration file. It does so using schemas generated from the Kubernetes OpenAPI specification, and therefore can validate schemas for multiple versions of Kubernetes.

$ kubeval my-invalid-rc.yaml
WARN - fixtures/my-invalid-rc.yaml contains an invalid ReplicationController - spec.replicas: Invalid type. Expected: [integer,null], given: string
$ echo $?
