Get started

You can deploy Kong Ingress Controller on any Kubernetes cluster which supports a Service of type: LoadBalancer.

You can use Minikube on your local machine or use a hosted k8s service like GKE.

To setup Kong Ingress Controller in your k8s cluster, execute:

helm install stable/kong --set ingressController.enabled=true

If you don't have helm installed on your k8s cluster, execute:

kubectl apply -f https://bit.ly/kong-ingress

You can also spin up Kong Ingress Controller without a database dependency:

kubectl apply -f https://bit.ly/kong-ingress-dbless

It takes a few minutes for all components to spin up. You now have set up Kong as your Ingress controller and all Ingress resources in your Kubernetes Cluster will be satisfied.

Please refer to our deployment documentation for a detailed introduction to Kong Ingress Controller and Ingress spec.

⚠️ Kong Ingress Controller takes care of managing all entities in Kong's datastore as per the Ingress and custom resource definitions in k8s. Any entity created using Kong's Admin API will be deleted by the Ingress Controller.

Design

Kong Ingress Controller is built to satisfy the Ingress spec in Kubernetes. Kong Ingress Controller is a Go app that listens to events from the API-server of your Kubernetes cluster and then sets up Kong to handle your configuration accordingly, meaning you never have to configure Kong yourself manually.

The controller can configure any Kong cluster via a Kong node running either in a control-plane mode or running both, control and data planes.

For detailed design, please refer to our design documentation.
