Demo: A customizable toolchain to validate Kubernetes manifests for robust deployment

We demonstrate a new customizable toolchain for validating Kubernetes manifests. The toolchain supports multiple types of validation, including validations against JSON schema, Kubernetes built-in rules, best practices, and custom business rules expressed in Common Expression Language (CEL). It also enables the detection of inconsistencies within a defined set of rules. The main goal is to highlight the value of each validation type and demonstrate how their combination improves the robustness of Kubernetes manifests, ensuring reliable deployments.
