# Install Cluster Ingress

Cluster Ingress for Kubernetes is currently deployed manually outside of UCP.
Future plans for UCP include managing the full lifecycle of the Ingress
components themselves. This guide describes how to manually deploy Ingress using
Kubernetes deployment manifests.

## Offline Installation

If you are installing Cluster Ingress on a UCP cluster that does not have access
to the Docker Hub, you will need to pre-pull the Ingress container images. If
your cluster has access to the Docker Hub, you can move on to [deploying cluster
ingress](#deploy-cluster-ingress)

Without access to the Docker Hub, you will need to download the container images
on a workstation with access to the internet. Container images are distributed
in a `.tar.gz` and can be downloaded at the following
[URL](https://s3.amazonaws.com/docker-istio/istio-ingress-1.1.2.tgz).

Once the container images have been downloaded, they would then need to be
copied on to the hosts in your UCP cluster, and then side loaded in Docker.
Images can be side loaded with:

```bash
$ docker load -i ucp.tar.gz
```

There images should now be present on your nodes:

```bash
$ docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE

docker/proxyv2          1.1.2               bebabbe114a4        6 days ago          360MB
docker/pilot            1.1.2               58b6e18f3545        6 days ago          299MB
```

## Deploy Cluster Ingress

This step deploys the Ingress controller components `istio-pilot` and
`istio-ingressgateway`. Together, these components act as the control-plane and
data-plane for ingress traffic. These components are a simplified deployment of
Istio cluster Ingress functionality. Many other custom K8s resources (CRDs) are
also created that aid in the Ingress functionality. 

> **Note**: This does not deploy the service mesh capabilities of Istio as its
> function in UCP is for Ingress.

As Cluster Ingress is not built into UCP in this release, a Cluster Admin will
need to manually download and apply the following Kubernetes Manifest
[file](https://s3.amazonaws.com/docker-istio/istio-ingress-1.1.2.yaml). 

1) Download the Kubernetes manifest yaml 

```bash
$ wget https://s3.amazonaws.com/docker-istio/istio-ingress-1.1.2.yaml
```
2) Source a [UCP Client Bundle](/ee/ucp/user-access/cli/)

3) Deploy the Kubernetes manifest file

```bash
$ kubectl apply -f istio-ingress-1.1.2.yaml
```

4) Check the installation has been completely succesfully. It may take a minute
   or 2 for all pods to become ready.

```
 kubectl get pods -n istio-system -o wide

```

5) Test the Ingress Deployment

To test that the Envory proxy is working correclty in the Isitio Gateway pods,
there is a status port configured on an internal port 15020. From the above
output we can see that port 15020 is exposed as a Kubernetes NodePort, in the
output above the NodePort is 34300 put this could be different in each
environment. 

To check the envoy proxy's status, there is a health endpoint at
`/healthz/ready`.

```bash
# Node Port
$ PORT=$(kubectl get service -n istio-system istio-ingressgateway --output jsonpath='{.spec.ports[?(@.name=="status-port")].nodePort}')
