Kubernetes Ingress Controller
An ingress controller for the Kong Gateway
The design document explains how the Kubernetes Ingress Controller works
inside a Kubernetes cluster and configures Kong to proxy traffic as per
rules defined in the Ingress 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 Kubernetes 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.
The Kubernetes 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 Kubernetes Ingress Controller is designed to scale with your traffic
Refer to the High-availability and Scaling guide to understand
failures scenarios, recovery methods, as well as scaling considerations.
Ingress classes filter which resources the
controller loads. They ensure that Kubernetes Ingress Controller instances do not
load configuration intended for other instances or other ingress controllers.
Refer to the Security concepts guide to understand the
default security settings and how to further secure the Ingress Controller.

a specific setting with the Kubernetes Ingress Controller.
The configurations in the Kubernetes Ingress Controller can be tweaked using
Custom Resources and annotations.
