Deploy a Micro Service Built on YaaS on the SAP Cloud Platform


Deploy a Micro Service Built on YaaS on the SAP Cloud Platform

By Seyedehmorvarid Khademhaghighat

In this tutorial you will set up a cloud account on the SAP Cloud Platform through your YaaS project. You will then deploy your Tips micro service to the cloud and point your Storefront to it.


You will learn

In this tutorial you will learn how to deploy a micro service to the SAP Cloud Platform. As an example you will use the Tips micro service created in Extend the YaaS Storefront’s Functionality with a Micro Service tutorial. In order to deploy a micro service you will need to set up your Cloud Foundry Command Line interface and create a SAP Cloud Platform account. In the end you will run the micro service on the cloud.

You will get most from this tutorial if you already have basic knowledge of Node.js, Angular and Restangular. If you are not already familiar with them and would like to dive into the code, you can follow the provided links to start learning.

Step 1: Download Cloud Foundry CLI

Download the Cloud Foundry CLI: Go to, and install Cloud Foundry’s CLI. Run cf commands from your command line to verify your installation.

CF Command
Step 2: Set endpoint

Set the Cloud Foundry CLI’s endpoint to SAP’s SAP Cloud Platform address, by running the command: cf api

CF Endpoint
Step 3: Subscribe to HCP, starter edition for cloud foundry services

Go to Builder. Choose the YaaS Project which you created in the Getting Started with YaaS tutorial to subscribe to the HCP, starter edition for cloud foundry services (beta) package. This package allows you to develop, deploy and run services and applications.
- Open your YaaS Projects Administration page.
- Click Subscription, select + Subscription, select the Beta Worldwide tab, and subscribe to the package called HCP, STARTER EDITION FOR CLOUD FOUNDRY SERVICES (BETA) in there.

Step 4: Check status in Builder

Wait 10 seconds and your package will appear in Builder. If your package did not appear, log out and back in to the YaaS Builder, find your project, and you should see SAP Cloud Platform in your YaaS Project’s Menu on the left side of the page.

Step 5: Activate your SAP Cloud Platform account

You should now get an email from HCP, guiding you through steps to activate your SAP Cloud Platform account.

NOTE: You can skip this step if you already have an HCP Account.

Step 6: Log in

You can then log in using the command cf login. After entering your credentials, your SAP Cloud Platform cloud foundry account will be ready to deploy to.

Step 7: View manifest file

Familiarize yourself with the manifest.yml file which is located on the root folder of your Tips Service in your folder (2)/yaasbite200. This is the file that instructs your Cloud Foundry CLI where and how to deploy your war file.

NOTE: If you have skipped the tutorial Extend the YaaS Storefront’s Functionality with a Micro Service, you can clone the Tips Micro Service with this command. git clone

Step 8: Set deployment name

Ensure your deployment name is unique to you, by adjusting the name value in the file manifest.yml to for example yourNameTipsService. This will ensure that your application will not clash with other applications deployed to the same environment by other users.

Name Value
Step 9: Check for Maven

  1. Run mvn -v to confirm that you have maven installed. If not, follow instructions on Apache Maven Website, and confirm that mvn -v then runs. Now build and package your micro service into a war file, by running the command mvn clean package from the folder (2)/yaasbite200.
Step 10: Push the war file to the cloud

Push the war file to the cloud, by running cf push from the same location. This will use the information in manifest.yml to guide the deployment.

Step 11: Check that the war file was deployed

Run cf apps to check whether the war file was successfully deployed and started and note the URL where it is running. It should be something like

NOTE: The default SAP Cloud Platform settings require the secure, https protocol. Therefore you must use https for all calls to your deployed services and when accessing your website in the cloud @ https://

Step 12: Register service in the YaaS Builder

Now that your service has been deployed to the cloud, you could access it directly from your StoreFront. However, YaaS is all about security, so instead we should register this service in the YaaS Builder, so that instead, we can access it via the YaaS Security Proxy. To register your service on YaaS:
- Go to your YaaS Project’s page.
- Select Services, select + Service and here you need to add the URL to your service on HCP:
- Enter the other required fields and then click Save.

  • Click the Deploy button and you will see a Generated Proxy URL which is the URL to your service on YaaS. Calls to this address will be checked by the YaaS Security framework and only if okay, passed along to your service.

NOTE: In order to access your service at the Generated Proxy URL you will need to acquire an Access Token. This is because all calls to a service on YaaS are secured. If you are interested to learn more about this please refer to YaaS Dev Portal.
