-### Ingress Kong
-
-Deploy [Kong Ingress Controller (KIC)](https://docs.konghq.com/kubernetes-ingress-controller/2.1.x/concepts/design/).
-
-{{< codeFromInline lang="bash" >}}
-kubectl apply -f https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/master/deploy/single/all-in-one-dbless.yaml
-{{< /codeFromInline >}}
-
-Apply kind specific patches to forward the `hostPorts` to the ingress controller, set taint tolerations, and schedule it to the custom labeled node.
-
-```json
-{{% readFile "static/examples/ingress/kong/deployment.patch.json" %}}
-```
-
-Apply it by running:
-
-{{< codeFromInline lang="bash" >}}
-kubectl patch deployment -n kong proxy-kong -p '{{< minify file="static/examples/ingress/kong/deployment.patch.json" >}}'
-{{< /codeFromInline >}}
-
-Apply kind specific patch to change service type to `NodePort`:
-
-```json
-{{% readFile "static/examples/ingress/kong/service.patch.json" %}}
-```
-
-Apply it by running:
-
-{{< codeFromInline lang="bash" >}}
-kubectl patch service -n kong kong-proxy -p '{{< minify file="static/examples/ingress/kong/service.patch.json" >}}'
-{{< /codeFromInline >}}
-
-KIC can be used to configure ingress now.
-
-You can try the example in [Using Ingress](#using-ingress) at this moment,
-but KIC will not automatically handle `Ingress` object defined there.
-`Ingress` resources must include `ingressClassName: kong` under `spec` of `Ingress`  for being controlled by Kong Ingress Controller (it will be ignored otherwise).
-So once the example has been loaded, you can add this annotation with:
-
-{{< codeFromInline lang="bash" >}}
-kubectl patch ingress example-ingress -p '{"spec":{"ingressClassName":"kong"}}'
-{{< /codeFromInline >}}
-
-Refer [Using Ingress](#using-ingress) for primary example usage.
