Lessons learned building Kubernetes controllers

Please log in to watch this conference skillscast.

In this talk I'll discuss my experiences building Kubernetes controllers using as a case study Contour, a new Kubernetes Ingress controller, that I've been working on since joining Heptio.

This presentation will cover:

• What an ingress controller is and what role it plays in a Kubernetes cluster.
• Why Heptio chose Lyft's Envoy proxy as the data plane for our ingress controller.
• How Contour works as a translator from Kubernetes to Envoy. The parts that were a good match, the parts that weren’t, and how we dealt with it.
• How to develop a component of an interactive system like Kubernetes while avoiding the dreaded compile/push/deploy time sink.
