Gatekeeper

Static Badge

How is Gatekeeper different from OPA?

Compared to using OPA with its sidecar kube-mgmt (aka Gatekeeper v1.0), Gatekeeper introduces the following functionality:

  • An extensible, parameterized policy library
  • Native Kubernetes CRDs for instantiating the policy library (aka "constraints")
  • Native Kubernetes CRDs for extending the policy library (aka "constraint templates")
  • Native Kubernetes CRDs for mutation support
  • Audit functionality
  • External data support

Getting started

Check out the installation instructions to deploy Gatekeeper components to your Kubernetes cluster.

Documentation

Please see the Gatekeeper website for more in-depth information.

Policy Library
