# Kong Ingress Controller for Kubernetes (KIC)



Use [Kong][kong] for Kubernetes [Gateway API][gwapi] or [Ingress][ingress].

Configure [plugins][docs-konghq-hub], health checking,

load balancing and more, all using

Custom Resource Definitions (CRDs) and Kubernetes-native tooling.



[**Features**](#features) | [**Get started**](#get-started) | [**Documentation**](#documentation) | [**main branch builds**](#main-branch-builds) | [**Seeking help**](#seeking-help)



## Features



- **Gateway API support**

  Use [Gateway API][gwapi] resources (official successor of [Ingress][ingress] resources) to configure Kong.

  Native support for TCP, UDP, TLS, gRPC and HTTP/HTTPS traffic, reuse the same gateway for multiple protocols and namespaces.

- **Ingress support**

  Use [Ingress][ingress] resources to configure Kong.

- **Declarative configuration for Kong**

  Configure all of Kong features in declarative Kubernetes native way with CRDs.

- **Seamlessly operate Kong**

  Scale and manage multiple replicas of Kong Gateway automatically to ensure performance and high-availability.

- **Health checking and load-balancing**

  Load balance requests across your pods and supports active & passive health-checks.

- **Enhanced API management using plugins**

  Use a wide array of [plugins][docs-konghq-hub] for e.g.

  - authentication

  - request/response transformations

  - rate-limiting



## Get started (using Helm)



You can use [Minikube or Kind][k8s-io-tools] on your local machine or use

a hosted Kubernetes service like [GKE](https://cloud.google.com/kubernetes-engine/).



### Install the Gateway API CRDs



This command will install all resources that have graduated to GA or beta,

including `GatewayClass`, `Gateway`, `HTTPRoute`, and `ReferenceGrant`.



```shell

kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/standard-install.yaml

```



Or, if you want to use experimental resources and fields such as `TCPRoute`s and `UDPRoute`s,

please run this command.



```shell

kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/experimental-install.yaml

```



### Install the Kong Ingress Controller with Helm



```shell

helm install kong --namespace kong --create-namespace --repo https://charts.konghq.com ingress

```



To learn more details about Helm chart follow the [Helm chart documentation](https://charts.konghq.com/).



Once installed, please follow the [Getting Started guide][docs-konghq-getting-started-guide]

to start using Kong in your Kubernetes cluster.



> Note: Kong Enterprise users, please follow along with our

[enterprise guide][docs-konghq-k4k8s-enterprise-setup] to setup the enterprise version.



## Get started (using Operator) 



As an alternative to Helm, you can also install Kong Ingress Controller using the **Kong Gateway Operator** by following this [quick start guide][kgo-guide].
