Yeoman Generator to jump-start BTP Full-Stack Cloud Applications

Installation

This generator creates projects using SAP Cloud Application Programming Model (CAP)

First, install Yeoman and generator-saphanaacademy-cap using npm

npm install -g yo
npm install -g generator-saphanaacademy-cap

SAP BTP, Cloud Foundry runtime

We assume you have pre-installed node.js and the Cloud Foundry CLI with the multiapps plugin.

In order to build the project ensure @sap/cds-dk and Cloud MTA Build Tool (MBT) are installed.

This is already the case for SAP Business Application Studio.

If using SAP HANA Cloud ensure you have created an instance and have configured a database mapping to the SAP BTP, Cloud Foundry runtime org and space that you will be deploying to.

If using the HTML5 Application Repository ensure you have subscribed to the SAP Launchpad service in the subaccount where you'll be deploying the app.

If enabling Continuous Integration and Delivery (CI/CD) ensure you have subscribed to the Continuous Integration & Delivery service and optionally the Transport Management service in the subaccount where you'll be deploying the app.

Also ensure that you are logged in to the SAP BTP, Cloud Foundry runtime CLI and are targeting the org and space into which you want to deploy the app.

To generate your new project:

yo saphanaacademy-cap

NB: If you prefer a rich user experience when generating your projects consider the Application Wizard.

To refresh project files for an existing SAP HANA Cloud schema:

cd <projectName>
yo saphanaacademy-cap:schema

To refresh project files for an existing SAP HANA Cloud HDI Container:

cd <projectName>
yo saphanaacademy-cap:hdi

To refresh project files for SAP Graph:

cd <projectName>
yo saphanaacademy-cap:graph

SAP BTP, Kyma runtime

We assume you have pre-installed node.js, have a Docker Hub ID and the ability to build and push containers either via Docker Desktop or an alternative such as Paketo Builder with the pack CLI, Rancher Desktop or podman or a CI/CD pipeline with kaniko.

The Kubernetes command-line tool kubectl is required with the kubelogin extension.

In order to build or deploy the project via the Makefile ensure that GNU Make is installed.

In order to deploy the project ensure that Helm is installed or use a CI/CD pipeline.

If using SAP HANA Cloud ensure you have created an instance and have configured a database mapping to the SAP BTP, Kyma runtime namespace that you will be deploying to.

If using the HTML5 Application Repository ensure you have subscribed to the SAP Launchpad service in the subaccount where you'll be deploying the app.

If enabling Continuous Integration and Delivery (CI/CD) ensure you have subscribed to the Continuous Integration & Delivery service and optionally the Transport Management service in the subaccount where you'll be deploying the app.

Ensure that you have set the KUBECONFIG environment variable, have optionally created a namespace into which you would like to deploy the project and are logged in to Docker Hub. For example:

Mac/Linux:

chmod go-r {KUBECONFIG_FILE_PATH}
export KUBECONFIG={KUBECONFIG_FILE_PATH}
kubectl create ns dev
docker login

Windows:

$ENV:KUBECONFIG="{KUBECONFIG_FILE_PATH}"
kubectl create ns dev
docker login

You can also specify the path to your Kubeconfig file in the generator.

To generate your new project:

yo saphanaacademy-cap

NB: If you prefer a rich user experience when generating your projects consider the Application Wizard.

To refresh project files for an existing SAP HANA Cloud schema:

cd <projectName>
yo saphanaacademy-cap:schema

To refresh project files for an existing SAP HANA Cloud HDI Container:

cd <projectName>
yo saphanaacademy-cap:hdi

To refresh project files for SAP Graph:

cd <projectName>
yo saphanaacademy-cap:graph

To build and push your project containers to Docker Hub:

cd <projectName>
make docker-push

If you prefer, you can issue the build & push commands manually (see the generated /Makefile) or use a CI/CD pipeline.

To deploy your new project to SAP BTP, Kyma runtime:

cd <projectName>
make helm-deploy

If you prefer, you can issue the helm commands manually (see the generated /Makefile) or use a CI/CD pipeline.

To undeploy your new project from SAP BTP, Kyma runtime:

cd <projectName>
make helm-undeploy

Important

Please pay special attention to messages produced by the generator!
