Overview

This sample provides a CAP Service application that you can configure with any of the sample Order APIs.

This sample demonstrates how to:

• Create a development Namespace in the Kyma runtime.
• Configure and build an SAPUI5 Docker image.
• Deploy the frontend in the Kyma runtime which includes:
  • A ConfigMap that contains the URL to the backend API.
  • A Deployment of the frontend image with the ConfigMap mounted to a volume.
  • A Service to expose the UI to other Kubernetes resources.
  • An API to expose the frontend externally.

Prerequisites

• SAP BTP, Kyma runtime instance
• Docker
• Docker Hub Account
• Node.js
• kubectl configured to use the KUBECONFIG file downloaded from the Kyma runtime.

Steps

Run the frontend locally

1. Clone the project.

2. Inside the directory, run:

npm install

3. Install the CAP tools

npm i -g @sap/cds-dk

4. Verify the CAP tools install by running

cds

5. Deploy the DB schemas to you local sqlite database

cds deploy --to sqlite

6. Run the app using the command

cds watch

The application loads at http://localhost:4004.

Build the Docker image

1. Build and push the image to your Docker repository:

docker build -t <your-docker-id>/cap-service -f docker/Dockerfile .
docker push {your-docker-account}/cap-service

```

2. To run the image locally, adjust the value of the **API_URL** parameter in the `webapp/config.js` file and mount it into the image:

```
docker run -p 4004:4004 <dockerid>/cap-service:latest --name cap-service

Deploy the application

1. Create a new dev Namespace:

kubectl create namespace dev

2. Apply the Resources:

kubectl -n dev apply -f ./k8s/deployment.yaml
kubectl -n dev apply -f ./k8s/apirule.yaml

3. Use the APIRule to open the application:

https://cap-service.{cluster-domain}
