Kubewarden

Kubewarden is a policy engine for Kubernetes. It helps with keeping your Kubernetes clusters secure 🔐 and compliant ✔.

Kubewarden policies can be written using regular programming languages or Domain Specific Languages (DSL).

Policies are compiled into WebAssembly modules that are then distributed using traditional container registries.
