Kong Ingress Controller

An ingress controller for the Kong Gateway

Concepts

Architecture

The design document explains how the Kong Ingress Controller works inside a Kubernetes cluster and configures Kong to proxy traffic as per rules defined in the Ingress resources.

Custom Resources

The Ingress resource in Kubernetes is a fairly narrow and ambiguous API, and doesn’t offer resources to describe the specifics of proxying. To overcome this limitation, the KongIngress Custom resource is used as an “extension” to the existing Ingress API.

A few custom resources are bundled with the Kong Ingress Controller to configure settings that are specific to Kong and provide fine-grained control over the proxying behavior.

Refer to the custom resources concept document for more details.

Deployment Methods

The Kong Ingress Controller can be deployed in a variety of deployment patterns. Refer to the deployment documentation, which explains all the components involved and different ways of deploying them based on the use-case.

High-availability and Scaling

The Kong Ingress Controller is designed to scale with your traffic and infrastructure. Refer to the High-availability and Scaling guide to understand failures scenarios, recovery methods, as well as scaling considerations.

Ingress classes

Ingress classes filter which resources the controller loads. They ensure that Kong Ingress Controller instances do not load configuration intended for other instances or other ingress controllers.

Security

Refer to the Security concepts guide to understand the default security settings and how to further secure the Ingress Controller.
