The introduction of S/4HANA Cloud SDK makes it even easier to develop cloud applications and integration with back-end SAP and cutting-edge tools and technologies like Hystrix, Docker, and Jenkins.

In this blog, I’m showing you how to deploying a Hello World application on SAP Cloud Foundry without any coding using S/4HANA Cloud SDK.

Prerequisite

Make sure you have a trial account on Cloud Foundry. If not, get one from here.

Make sure your PC has the following installed:

• JDK
• Maven
• Cloud Foundry CLI

On Windows, you can use these commands to install those softwares with Chocolatey:

choco install jdk8
choco install maven
choco install cloudfoundry-cli

Generate Project

Use this command to generate Maven project from Archtype:

mvn archetype:generate -DarchetypeGroupId=com.sap.cloud.s4hana.archetypes -DarchetypeArtifactId=scp-cf-spring -DarchetypeVersion=LATEST

Enter project information as you wish. Here is mine for your example:

groupId: me.chairat.scp.spring.hello
artifactId: hellospring
version: 1.0-SNAPSHOT (Just press ENTER)
package: me.chairat.scp.spring.hello (Just press ENTER)
uniqueHostname: hellospring-chairat

You will get a project folder with a few sub modules. Get into the folder and build it with this command:

mvn clean package

Deploying to Cloud

Time to deploy to the cloud. Use the following set of commands:

cf api https://api.cf.eu10.hana.ondemand.com
cf login
cf push

Your application will be built, deployed, and started automatically in a while. If everything is okay, you should see this message:

Go to Cloud Cockpit and click the link to open your application.

Hola! My next step is to play around with Jenkins.
