Deploy in SAP BTP, Cloud Foundry Runtime

The SAP BTP, Cloud Foundry environment allows you to create polyglot cloud applications in Cloud Foundry. It contains the SAP BTP, Cloud Foundry runtime, which is based on the open-source application platform managed by the Cloud Foundry Foundation.

The SAP BTP, Cloud Foundry environment enables you to develop new business applications and business services, supporting multiple runtimes, programming languages, libraries, and services.

For more information about the Cloud Foundry environment, see Cloud Foundry Environment.

A multitarget application (MTA) is logically a single application comprised of multiple parts created with different technologies, which share the same lifecycle.

The developers of the MTA describe the desired result using the MTA model which contains MTA modules, MTA resources and interdependencies between them. Afterwards, the MTA deployment service validates, orchestrates, and automates the deployment of the MTA, which results in Cloud Foundry (CF) applications, services and SAP-specific contents.

You will use the Cloud MTA Build Tool to deploy the Incident Management application. The modules and services are configured in the mta.yaml deployment descriptor file.

1. In SAP Business Application Studio, go to your IncidentManagement dev space.

   Make sure the IncidentManagement dev space is in status RUNNING.

2. From the root of the INCIDENT-MANAGEMENT project, choose the burger menu, and then choose Terminal → New Terminal.

3. Run the following command to generate the mta.yaml deployment descriptor:

   bash

   Copy

   cds add mta
   

You can create a CAP project in either Node.js or Java. You have to choose one way or the other and follow through. The tabs Node.js and Java provide detailed steps for each alternative way.

Run the following commands to assemble everything into a single mta.tar archive:

npm install
mbt build

See Multitarget Applications in the Cloud Foundry Environment to learn more about MTA-based deployment.

In the next tutorials, you will access your UIs from SAP Build Work Zone, standard edition. The SAP Build Work Zone, standard edition will trigger the authentication flow to provide the required token to access the service.
