--- title: Set up Ingress on Minikube with the NGINX Ingress Controller content_type: task weight: 100 min-kubernetes-server-version: 1.19 --- 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. This page shows you how to set up a simple Ingress which routes requests to Service web or web2 depending on the HTTP URI. ## {{% heading "prerequisites" %}} {{< include "task-tutorial-prereqs.md" >}} {{< version-check >}} If you are using an older Kubernetes version, switch to the documentation for that version. ### Create a Minikube cluster Using Katacoda : {{< kat-button >}} Locally : If you already [installed Minikube](/docs/tasks/tools/#minikube) locally, run `minikube start` to create a cluster. ## 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 {{< tabs name="tab_with_md" >}} {{% tab name="minikube v1.19 or later" %}} ```shell kubectl get pods -n ingress-nginx ``` {{< note >}}It can take up to a minute before you see these pods running OK.{{< /note >}} The output is similar to: ``` NAME READY STATUS RESTARTS AGE ingress-nginx-admission-create-g9g49 0/1 Completed 0 11m ingress-nginx-admission-patch-rqp78 0/1 Completed 1 11m ingress-nginx-controller-59b45fb494-26npt 1/1 Running 0 11m ``` {{% /tab %}} {{% tab name="minikube v1.18.1 or earlier" %}} ```shell kubectl get pods -n kube-system ``` {{< note >}}It can take up to a minute before you see these pods running OK.{{< /note >}} The output is similar to: ``` 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 ``` Make sure that you see a Pod with a name that starts with `nginx-ingress-controller-`. {{% /tab %}} {{< /tabs >}} ## Deploy a hello, world app 1. Create a Deployment using the following command: ```shell kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0 ``` The output should be: ``` deployment.apps/web created ``` 1. Expose the Deployment: ```shell kubectl expose deployment web --type=NodePort --port=8080 ``` The output should be: ``` service/web exposed ``` 1. Verify the Service is created and is available on a node port: ```shell kubectl get service web ``` The output is similar to: ``` NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE web NodePort 10.104.133.249 8080:31637/TCP 12m ``` 1. Visit the Service via NodePort: ```shell minikube service web --url ``` The output is similar to: ``` 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 >}} The output is similar to: ``` 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 The following manifest defines an Ingress that sends traffic to your Service via hello-world.info. 1. Create `example-ingress.yaml` from the following file: {{< codenew file="service/networking/example-ingress.yaml" >}} 1. Create the Ingress object by running the following command: ```shell kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml ``` The output should be: ``` ingress.networking.k8s.io/example-ingress created ``` 1. Verify the IP address is set: ```shell kubectl get ingress ``` {{< note >}}This can take a couple of minutes.{{< /note >}} You should see an IPv4 address in the ADDRESS column; for example: ``` NAME CLASS 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 on your computer (you will need administrator access): ``` 172.17.0.15 hello-world.info ``` {{< 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 >}} After you make this change, your web browser sends requests for hello-world.info URLs to Minikube. 1. Verify that the Ingress controller is directing traffic: ```shell curl hello-world.info ``` You should see: ``` 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 a second Deployment 1. Create another Deployment using the following command: ```shell kubectl create deployment web2 --image=gcr.io/google-samples/hello-app:2.0 ``` The output should be: ``` deployment.apps/web2 created ``` 1. Expose the second Deployment: ```shell kubectl expose deployment web2 --port=8080 --type=NodePort ``` The output should be: ``` service/web2 exposed ``` ## Edit the existing Ingress {#edit-ingress} 1. Edit the existing `example-ingress.yaml` manifest, and add the following lines at the end: ```yaml - path: /v2 pathType: Prefix backend: service: name: web2 port: number: 8080 ``` 1. Apply the changes: ```shell kubectl apply -f example-ingress.yaml ``` You should see: ``` ingress.networking/example-ingress configured ``` ## Test your Ingress 1. Access the 1st version of the Hello World app. ```shell curl hello-world.info ``` The output is similar to: ``` 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 ``` The output is similar to: ``` 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 >}} ## {{% heading "whatsnext" %}} * Read more about [Ingress](/docs/concepts/services-networking/ingress/) * Read more about [Ingress Controllers](/docs/concepts/services-networking/ingress-controllers/) * Read more about [Services](/docs/concepts/services-networking/service/)
