kube-lint

Allows defining validation rules using YAML configuration with JSONPath field selection, enabling organizations to enforce their own standards rather than relying on defaults.

Supports running subsets of rules by filtering based on tags like 'security' or 'operations,' which is useful for targeted audits and CI/CD gating, as shown in the README examples.

Implements support for string, boolean, and numeric value types with operators like equal, set, and greaterthan, allowing for diverse validation scenarios based on the rule configuration.

Can evaluate resources only from specific Kubernetes namespaces via the --namespace flag, aiding in focused validation efforts for cluster auditing.
