Contour is an Ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer,” the Contour GitHub project page states. “Unlike other Ingress controllers, Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile.”
The Envoy open-source project was originally developed by ride-sharing service Lyft and officially became a Cloud Native Computing Foundation (CNCF) project on Sept. 13. The CNCF is the home multiple open-source efforts, including the Kubernetes container orchestration platform.
