Kong Ingress Controller for Kubernetes

Here you go! https://github.com/Kong/kubernetes-ingress-controller/issues/729

The key to handling modern dynamic, scalable workloads in Kubernetes is a networking stack that can deliver API management, a service mesh and an ingress controller. Kong Ingress Controller allows users to manage the routing rules that control external user access to the service in a Kubernetes cluster from the same platform.

For those organizations using Kubernetes for their container orchestration, Kong created the Kong Ingress Controller which implements authentication, transformations, and other functionalities (via plugins) across Kubernetes clusters. Kong Ingress Controller updates a standard Kubernetes implementation as shown below:

This article will walk through how easy it is to set up the open source Kong Ingress Controller as a Kubernetes API gateway on a cluster.

But here is the tricky part. There are lots of Ingress Controllers available. Some of them are opensource, but some of them are paid one. For this project I’ve chosen an “official” Kubernetes Ingress Controller based on Nginx. But please be not confused with another one, also based on Nginx but created by NGINX Inc - this one is paid. Apart from these both there are also other* Ingress Controller*s available like Kong Ingress, or Traefik.

So my advice is: Don‘t implement anything someone else already did better and have a look at Skipper: https://github.com/zalando/skipper

That's all! You can find a complete example of an Admit func from the Validating Admission Webhook in Skipper. I've also included an abridged version at the end of this blog post.

This series is based on my experience adding a ValidatingAdmissionWebhook to Skipper, modern HTTP proxy.

You can find an abridged version of admission.Handler under "Reference". For a complete example of a validating admission webhook being used in production, checkout the validating admission webhook in Skipper, our HTTP reverse proxy.
