+# Eclipse JKube Vert.x 4 Web Quickstart
+Eclipse Vert.x 4 Web example application declaring a Simple AbstractVerticle.
+
+### Steps to use
+
+Make sure that Kubernetes/OpenShift cluster or Minikube/minishift is running. 
+
+#### For OpenShift
+```shell
+$ minishift start
+```
+Below command will create your OpenShift resource descriptors.
+```shell
+$ mvn -Popenshift clean oc:resource
+```
+
+Now start S2I build  by hitting the build goal.
+```shell
+
+$ mvn -Popenshift package oc:build
+```
+
+Below command will deploy your application on OpenShift cluster.
+```shell
+$ mvn -Popenshift oc:apply
+```
+
+#### For Kubernetes
+Start your cluster:
+```shell
+$ minikube start
+```
+Below command will create your Kubernetes resource descriptors.
+```shell
+$ mvn -Pkubernetes clean k8s:resource
+```
+
+Now start docker build  by hitting the build goal.
+```shell
+$ mvn -Pkubernetes package k8s:build
+```
+
+Below command will deploy your application on Kubernetes cluster.
+```shell
+$ mvn -Pkubernetes k8s:deploy
+```
