Contour 
Overview
Contour is an Ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer. Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile.
Contour also introduces a new ingress API (HTTPProxy) which is implemented via a Custom Resource Definition (CRD). Its goal is to expand upon the functionality of the Ingress API to allow for a richer user experience as well as solve shortcomings in the original design.
Prerequisites
Contour is tested with Kubernetes clusters running version 1.10 and later, but should work with earlier versions where Custom Resource Definitions are supported (Kubernetes 1.7+).
RBAC must be enabled on your cluster.
Get started
Getting started with Contour is as simple as one command. See the Getting Started document.
Troubleshooting
If you encounter issues, review the troubleshooting docs, file an issue, or talk to us on the #contour channel on the Kubernetes Slack server.
