{{% capture overview %}}

An [Ingress](/docs/concepts/services-networking/ingress/) is an API object that defines rules which allow external access 
to services in a cluster. An [Ingress controller](/docs/concepts/services-networking/ingress-controllers/) fulfills the rules set in the Ingress. 

{{< caution >}}
For the Ingress resource to work, the cluster **must** also have an Ingress controller running.
{{< /caution >}}

This page shows you how to set up a simple Ingress which routes requests to Service web or web2 depending on the HTTP URI.

## Create a Minikube cluster

1. Click **Launch Terminal**

    {{< kat-button >}}

1. (Optional) If you installed Minikube locally, run the following command:

    ```shell
    minikube start
    ```

## Enable the Ingress controller

1. To enable the NGINX Ingress controller, run the following command:

    ```shell
    minikube addons enable ingress
    ```
      
1. Verify that the NGINX Ingress controller is running

    ```shell
    kubectl get pods -n kube-system
    ```

    {{< note >}}This can take up to a minute.{{< /note >}}

    Output:

    ```shell
    NAME                                        READY     STATUS    RESTARTS   AGE
    default-http-backend-59868b7dd6-xb8tq       1/1       Running   0          1m
    kube-addon-manager-minikube                 1/1       Running   0          3m
    kube-dns-6dcb57bcc8-n4xd4                   3/3       Running   0          2m
    kubernetes-dashboard-5498ccf677-b8p5h       1/1       Running   0          2m
    nginx-ingress-controller-5984b97644-rnkrg   1/1       Running   0          1m
    storage-provisioner                         1/1       Running   0          2m
    ```

## Deploy a hello, world app

1. Create a Deployment using the following command:

    ```shell
    kubectl run web --image=gcr.io/google-samples/hello-app:1.0 --port=8080
    ```

    Output:
    
    ```shell
    deployment.apps/web created
    ```

1. Expose the Deployment: 

    ```shell
    kubectl expose deployment web --target-port=8080 --type=NodePort
    ```
    
    Output: 
    
    ```shell
    service/web exposed
    ```
    
1. Verify the Service is created and is available on a node port:

    ```shell
    kubectl get service web
    ``` 
    
    Output:
    
    ```shell
    NAME      TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
    web       NodePort   10.104.133.249   <none>        8080:31637/TCP   12m
    ```

1. Visit the service via NodePort:

    ```shell
    minikube service web --url
    ```
    
    Output:
    
    ```shell
    http://172.17.0.15:31637
    ```
    
    {{< note >}}Katacoda environment only: at the top of the terminal panel, click the plus sign, and then click **Select port to view on Host 1**. Enter the NodePort, in this case `31637`, and then click **Display Port**.{{< /note >}}
    
    Output:
    
    ```shell
    Hello, world!
    Version: 1.0.0
    Hostname: web-55b8c6998d-8k564
    ```
    
    You can now access the sample app via the Minikube IP address and NodePort. The next step lets you access 
    the app using the Ingress resource.

## Create an Ingress resource

The following file is an Ingress resource that sends traffic to your Service via hello-world.info.

1. Create `example-ingress.yaml` from the following file:

        apiVersion: extensions/v1beta1
        kind: Ingress
        metadata:
          name: example-ingress
          annotations:
            nginx.ingress.kubernetes.io/rewrite-target: /
        spec:
         rules:
         - host: hello-world.info
           http:
             paths:
             - path: /*
               backend:
                 serviceName: web
                 servicePort: 8080

1. Create the Ingress resource by running the following command:
    
    ```shell
    kubectl apply -f example-ingress.yaml
    ```
    
    Output:
    
    ```shell
    ingress.extensions/example-ingress created
    ```

1. Verify the IP address is set: 

    ```shell 
    kubectl get ingress
    ```

    {{< note >}}This can take a couple of minutes.{{< /note >}}

    ```shell
    NAME              HOSTS              ADDRESS       PORTS     AGE
    example-ingress   hello-world.info   172.17.0.15   80        38s
    ```

1. Add the following line to the bottom of the `/etc/hosts` file. 

    {{< note >}}If you are running Minikube locally, use `minikube ip` to get the external IP. The IP address displayed within the ingress list will be the internal IP.{{< /note >}}

    ```
    172.17.0.15 hello-world.info
    ```

    This sends requests from hello-world.info to Minikube.

1. Verify that the Ingress controller is directing traffic:

    ```shell
    curl hello-world.info
    ```

    Output:
    
    ```shell
    Hello, world!
    Version: 1.0.0
    Hostname: web-55b8c6998d-8k564
    ```

    {{< note >}}If you are running Minikube locally, you can visit hello-world.info from your browser.{{< /note >}}

## Create Second Deployment

1. Create a v2 Deployment using the following command:

    ```shell
    kubectl run web2 --image=gcr.io/google-samples/hello-app:2.0 --port=8080
    ```
    Output:
    
    ```shell
    deployment.apps/web2 created
    ```
    
1. Expose the Deployment:

    ```shell
    kubectl expose deployment web2 --target-port=8080 --type=NodePort
    ```

    Output: 
    
    ```shell
    service/web2 exposed
    ```
    
## Edit Ingress

1. Edit the existing `example-ingress.yaml` and add the following lines:  

    ```yaml
         - path: /v2/*
           backend:
             serviceName: web2
             servicePort: 8080
    ```

1. Apply the changes:

    ```shell
    kubectl apply -f example-ingress.yaml
    ```

    Output: 
    ```shell
    ingress.extensions/example-ingress configured
    ```

## Test Your Ingress

1. Access the 1st version of the Hello World app.

    ```shell
    curl hello-world.info
    ```

    Output:
    ```shell
    Hello, world!
    Version: 1.0.0
    Hostname: web-55b8c6998d-8k564
    ```

1. Access the 2nd version of the Hello World app.

    ```shell
    curl hello-world.info/v2
    ```

    Output:
    ```shell
    Hello, world!
    Version: 2.0.0
    Hostname: web2-75cd47646f-t8cjk
    ```

    {{< note >}}If you are running Minikube locally, you can visit hello-world.info and hello-world.info/v2 from your browser.{{< /note >}}
