What is Kubewarden?
Kubewarden is a universal policy engine for Kubernetes. Its mission is simplifying the adoption of policy-as-code.
As a Policy author
Kubewarden doesn't require you to learn a new Domain Specific Language or a query language.
Write policies in your favorite programming language. Reuse skills and be quickly productive.
As a Kubernetes Operator
Kubewarden policies can be distributed using container registries. Keep using your existing infrastructure and processes.
It's easy to experiment with policies and to integrate them into CI/CD pipelines.
Why Use Kubewarden
Freedom of choice
Write policies using your favorite programming language, as long as it can be compiled into WebAssembly.
Feel at home
Policies are regular programs. Use the tools you love, reuse your skills, libraries and best practices.
Portable
Policies are portable. Once built, they can run everywhere, regardless of the architecture and Operating System.
Adaptable
Kubewarden can also be used to validate non-Kubernetes admission requests. Its "raw" policies can be used to validate any kind of JSON document.
How it Works
Kubewarden integrates with Kubernetes by providing a set of Custom Resources. These Custom Resources simplify the process of enforcing policies on your cluster.
Policies are implemented as WebAssembly modules and are distributed using regular container registries. They are evaluated in a Kubewarden component called "Policy Server".
Kubewarden Policy Server is a Kubernetes Admission Webhook. Each policy is exposed using a dedicated endpoint. Policies are isolated from the host and from each other. Policies are confined inside a dedicated, secure sandbox.
