# Lets try deploying Nginx Webserver on Minikube Cluster

1. Create deployment for nginx server

$ kubectl run nginx --image=nginx:latest --port=80
deployment.apps "nginx" created

2. Create service to expose the nginx web server

$ kubectl expose deployment nginx --type=NodePort
service "nginx" exposed

3. Check Pod status

$ kubectl get pods
NAME                     READY     STATUS    RESTARTS   AGE
nginx-7dc954dcb5-6qqcz   1/1       Running   0          18s

4. Get endpoint and port on which nginx service is running, so that it can be accessed.

$ minikube service nginx --url
http://192.168.99.100:32688

Open above url in browser, you will see, nginx webserver up and running.
