Hello World on SAP BTP Kyma Runtime

This is a sample Hello World application for the SAP BTP Kyma Environment. It features a minimal Node.js app with express, that prints a simple "Hello World" message in the browser. That application will be containerized using docker and deployed to the Kyma Runtime in the SAP Business Technolgy Platform.

Installation

Run the following command to install all dependencies and start the application locally.

yarn install
yarn start

After that, open http://localhost:3000 to access the application.

Create Docker image

In order to deploy our application to the Kyma environment we need to create a Docker image first.

docker build . -t <your-user-name>/kyma-hello-world

Note: I pre-built the image and pushed it to the GitHub Docker registry as ghcr.io/eikeb/kyma-hello-world:latest.

Start the Docker image

After the Docker image has been created, use the following command to run it and map port 3000 in the container to port 43000 on the host machine.

docker run -p 43000:3000 -d <your-user-name>/kyma-hello-world

After that, open http://localhost:43000 to access the application that is running inside the docker container.

Create the Kyma Namespace

kubectl create namespace kyma-samples
kubectl apply -f app/k8s/manifest.yaml
