Kubernetes version 1.9 introduced two code packages that allow you to write custom admission plugins: ValidatingAdmissionWebhook and MutatingAdmissionWebhook. These plugins give you a great deal of flexibility to integrate directly into the resource admission process.

In this session, we will write some validating admission webhooks with Azure Functions and use them to apply governance policies on the deployments in Kubernetes. After completing this session, you will understand how easy it is to write custom validating webhooks for Kubernetes. You will be ready to automate your existing organizational deployment policies and certify deployments at scale in Kubernetes.
