Kubernetes JSON Schemas

Fork

This is a fork from instrumenta/kubernetes-json-schema with updated scripts for easier maintenance, as well as schemas for all recent Kubernetes versions.

This repository is kept up-to-date automatically every day using Github Actions.

Usage

Kubeconform

This is the default schema repository used by Kubeconform, and does not need to be specified. When using multiple schema repositories, this repo can be referred to using the alias default.

# All 3 are equivalent
$ kubeconform deployment.yaml
$ kubeconform -schema-location default deployment.yaml
$ kubeconform -schema-location 'https://raw.githubusercontent.com/yannh/kubernetes-json-schema/master/{{ .NormalizedKubernetesVersion }}-standalone{{ .StrictSuffix }}/{{ .ResourceKind }}{{ .KindSuffix }}.json' deployment.yaml
Summary: 1 resource found in 1 file - Valid: 1, Invalid: 0, Errors: 0, Skipped: 0

Kubeval

$ kubeval --strict --schema-location https://raw.githubusercontent.com/yannh/kubernetes-json-schema/master/ deployment.yaml
PASS - deployment.yaml contains a valid Deployment

To run kubeval against a specific Kubernetes version, pass the -v argument

$ kubeval -v 1.19.8 -s  https://raw.githubusercontent.com/yannh/kubernetes-json-schema/master ingress.yaml
PASS - ingress.yaml contains a valid Ingress (ingress)

Building the schemas yourself

The tooling for generating these schemas is a fork from the original openapi2jsonschema. See build.sh.

It's not Kubernetes specific and should work with other OpenAPI APIs too. This should be useful if you're using a pre-release or otherwise modified version of Kubernetes, or something like OpenShift which extends the standard APIs with additional types.
