SAP Community Code Challenge - Cloud Native

Coming Soon in July 2022

This repository is the starting point for the SAP Community Code Challenge for Cloud Native (see SAP Community Coffee Corner thread and corresponding blog post). It contains everything you need to get a basic Node.js based project deployed as a service to a Kubernetes based runtime.

That means you get the Node.js related files of the service, a Dockerfile and a Deployment.yaml file. If you're like "Oh Gosh, what is he talking about?" - No worries we will get to what all of that means.

The goal for this month's Coding Challenge is to bring the world of Kubernetes, Containerization and the SAP BTP, Kyma runtime closer to you so you have an easier start with the world of Cloud Native development.

Setup and Participation

To be able to take part in this challenge, it's essential that you first complete the following steps:

1. Fork this repository.
2. Clone the forked repository into your development environment.
3. Navigate into the service/ folder.
4. Execute npm install to install the project's dependencies.
5. Run npm start in order to test the project locally.
6. To try out if the service runs correctly open a web browser and type in
   1. http://localhost:8080
   2. http://localhost:8080/greeting/

The default port used in this local setup is 8080; you can specify a different one (e.g. 8000) if you need to, like this: PORT=8000 npm start

In order to complete each of the challenges, you need to:

1. Look into the Challenges file to see what the challenge is each week.
2. Depending on the challenge, you may need to submit information on the SAP Community Coffee Corner thread. Check the Challenges file to see what is required.

Because the challenges are there to give you an introduction to Cloud Native technologies like Kubernetes, Containers and the SAP BTP, Kyma runtime the service being provided is deliberately basic. This is so that you can focus more on understanding the fundamentals of this fairly complex topic. No worries there is more then enough content ready for you to feel like a Kubernetes pro after these 4 weeks! 🧑‍💻 😉

You can find the challenges for each week in the Challenges file.

Requirements

• Node.js version 16.x (https://nodejs.org/en/download/).
• Free Tier Account on SAP Business Technology Platform (see Get an Account on SAP BTP to Try Out Free Tier Service Plans)
• The SAP BTP, Kyma runtime enabled (see Enable the SAP BTP, Kyma runtime).
• In this project we use Docker but feel free to use any other container technology, note that if you do you can't use the Dockerfile provided.

Download and Installation
