Kubeconform validates Kubernetes YAML and JSON manifests against JSON schemas. It supports strict validation, custom resources, local schemas, and several output formats. A Kubernetes cluster is not required. Building requires google-go-lang (Go 1.26 or newer). Dependencies are included in the upstream source archive; compilation is offline. Go is not needed to run the built program. By default, schemas are downloaded from yannh/kubernetes-json-schema on GitHub. Internet access and CA certificates are needed for HTTPS schema downloads. Use -kubernetes-version to select the target Kubernetes version and -cache to retain downloaded schemas. For offline validation, supply local schemas with -schema-location: kubeconform -schema-location '/schemas/{{.ResourceKind}}.json' \ -summary manifest.yaml Custom resources require their own JSON schemas. Schema validation does not cover all server-side checks or prove that a workload will run. This package installs kubeconform only, not the separate schema converter. See Readme.md in /usr/doc/kubeconform-/ for schema templates, custom resource validation, and usage examples.
