Kong for Kubernetes Enterprise

Kong for Kubernetes Enterprise is an enhanced version of the Open-Source Ingress Controller. It includes all Enterprise plugins and comes with 24x7 support for worry-free production deployment. This is available only for enterprise customers of Kong, Inc.

Before you begin

Create the kong namespace in the cluster to create a secret.
```
 $ kubectl create namespace kong
```
The results should look like this:
```
 namespace/kong created
```
Create Kong Gateway Enterprise License secret

Kong Gateway Enterprise License secret

Enterprise version requires a valid license to run. As part of sign up for Kong Gateway Enterprise, you should have received a license file. If you do not have one, please contact your sales representative.

Save the license file temporarily to disk with filename license.json.
Deploy Kong Gateway Enterprise in the kong namespace. Ensure that you provide the file path where you have stored license.json file when you run the command. To deploy Kong Ingress Controller in a different namespace, change the value of -n kong.
```
 $ kubectl create secret generic kong-enterprise-license --from-file=license=./license.json -n kong
```
The results should look like this:
```
 secret/kong-enterprise-license created
```

Installing Kong Gateway Enterprise

Kong for Kubernetes Enterprise can be installed using an installer of your choice. After the installation is complete, see the getting started tutorial to learn more.

YAML manifests

Kustomize

Helm

Install Kong for Kubernetes Enterprise using YAML manifests.

 kubectl apply -f https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/v2.8.2/deploy/single/all-in-one-dbless-k4k8s-enterprise.yaml

The results should look like this:

 role.rbac.authorization.k8s.io/kong-leader-election created
 clusterrole.rbac.authorization.k8s.io/kong-ingress created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-crds created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-gateway created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-knative created
 rolebinding.rbac.authorization.k8s.io/kong-leader-election created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-crds created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-gateway created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-knative created
 service/kong-admin created
 service/kong-proxy created
 service/kong-validation-webhook created
 deployment.apps/ingress-kong created
 deployment.apps/proxy-kong created
 ingressclass.networking.k8s.io/kong created

Check if the Kong Ingress Controller is ready.

 $ kubectl get pods -n kong

The results should look like this:

 NAME                            READY   STATUS    RESTARTS   AGE
 ingress-kong-6ffcf8c447-5qv6z   2/2     Running   1          44m

It takes a few minutes the first time you set this up.

Check if the kong-proxy service is deployed.
```
 $ kubectl get service kong-proxy -n kong
```
The results should look like this:
```
 NAME         TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                      AGE
 kong-proxy   LoadBalancer   10.63.254.78   192.168.99.100   80:32697/TCP,443:32365/TCP   22h
```
Note: Depending on the Kubernetes distribution you are using, you might or might not see an external IP address assigned to the service. To obtain an IP address for a Kubernetes Service of type LoadBalancer, see your cloud provider’s documentation.
Kubernetes exposes the proxy through a Kubernetes service. Run the following commands to store the load balancer IP address in a variable named PROXY_IP:
```
 $ export PROXY_IP=$(kubectl get -o jsonpath="{.status.loadBalancer.ingress[0].ip}" service -n kong kong-proxy)
 echo $PROXY_IP
```
The results should look like this:
```
 192.168.99.100
```
Note: It may take a while for your cloud provider to actually associate the IP address to the kong-proxy Service.

Kustomize manifests are provided for illustration purposes only and are not officially supported by Kong. There is no guarantee of backwards compatibility or upgrade capabilities for our Kustomize manifests. For a production setup with Kong support, use the Helm chart.

Install Kong for Kubernetes using Kustomize:

 kubectl apply -k github.com/kong/kubernetes-ingress-controller/config/variants/enterprise

You can use this as a base kustomization and build on top of it for your cluster and use-case.

The results should look like this:

 role.rbac.authorization.k8s.io/kong-leader-election created
 clusterrole.rbac.authorization.k8s.io/kong-ingress created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-crds created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-gateway created
 clusterrole.rbac.authorization.k8s.io/kong-ingress-knative created
 rolebinding.rbac.authorization.k8s.io/kong-leader-election created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-crds created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-gateway created
 clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-knative created
 service/kong-admin created
 service/kong-proxy created
 service/kong-validation-webhook created
 deployment.apps/ingress-kong created
 deployment.apps/proxy-kong created
 ingressclass.networking.k8s.io/kong created

Kubernetes exposes the proxy through a Kubernetes service. Run the following commands to store the load balancer IP address in a variable named PROXY_IP:

 HOST=$(kubectl get svc --namespace kong kong-proxy -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
 PORT=$(kubectl get svc --namespace kong kong-proxy -o jsonpath='{.spec.ports[0].port}')
 export PROXY_IP=${HOST}:${PORT}
 echo $PROXY_IP  

The results should look like this:

 192.168.99.100:80

You can use Helm to install Kong using the official Helm chart:

Create a values.yaml file with these details to deploy using Helm charts.

 gateway:
     image:
       repository: kong/kong-gateway
       tag: 3.8.1.0
     env:
       LICENSE_DATA:
         valueFrom:
           secretKeyRef:
             name: kong-enterprise-license
             key: license

Install Kong Ingress Controller and Kong Gateway with Helm:

 $ helm repo add kong https://charts.konghq.com
 $ helm repo update
 $ helm install kong kong/ingress -n kong --create-namespace --values ./values.yaml

The results should look like this:
