Gatekeeper v1.0 - Uses OPA as the admission controller with the kube-mgmt sidecar enforcing configmap-based policies.Evolutionīefore we dive into the current state of Gatekeeper, let’s take a look at how the Gatekeeper project has evolved. Gatekeeper is a customizable admission webhook for Kubernetes that enforces policies executed by the Open Policy Agent (OPA), a policy engine for Cloud Native environments hosted by CNCF. ![]() Gatekeeper was created to enable users to customize admission control via configuration, not code and to bring awareness of the cluster’s state, not just the single object under evaluation at admission time. Kubernetes allows decoupling policy decisions from the API server by means of admission controller webhooks to intercept admission requests before they are persisted as objects in Kubernetes. All namespaces must have a label that lists a point-of-contact.All ingress hostnames must be globally unique.All images must be from approved repositories.With Kubernetes, how do you ensure compliance without sacrificing development agility and operational independence?įor example, you can enforce policies like: These policies may be there to meet governance and legal requirements or to enforce best practices and organizational conventions. If your organization has been operating Kubernetes, you probably have been looking for ways to control what end-users can do on the cluster and ways to ensure that clusters are in compliance with company policies. The following recordings from the Kubecon EU 2019 sessions are a great starting place in working with Gatekeeper: In this post, we will walk through the goals, history, and current state of the project. The Open Policy Agent Gatekeeper project can be leveraged to help enforce policies and strengthen governance in your Kubernetes environment.
