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 supports multiple configuration APIs in order to meet the needs of as many users as possible:

• Ingress - A stable upstream API that enables basic ingress use cases.
• HTTPProxy - Contour's Custom Resource Definition (CRD) which expands upon the functionality of the Ingress API to allow for a richer user experience as well as solve shortcomings in the original design.
• Gateway API - A new CRD-based API managed by the Kubernetes SIG-Network community that aims to evolve Kubernetes service networking APIs in a vendor-neutral way.

Prerequisites

See the compatibility matrix for the Kubernetes versions Contour is supported with.

RBAC must be enabled on your cluster.

Get started

Getting started with Contour is as simple as one command. See the Getting Started document.
