# DEV261 - Build Extensions with SAP BTP, Kyma Runtime

[![REUSE status](https://api.reuse.software/badge/github.com/SAP-samples/teched2021-DEV261)](https://api.reuse.software/info/github.com/SAP-samples/teched2021-DEV261)

## Description

This repository contains the material for the SAP TechEd 2021 session called DEV261 - "Build Extensions with SAP BTP, Kyma Runtime".

[The video replay is now available.](https://www.youtube.com/watch?v=5MwJQzRvijM)

## Overview

This session introduces attendees to making use of the advantages that come along with Kubernetes in the context of their SAP BTP projects. SAP BTP, Kyma runtime is the fully managed Kubernetes runtime based on the open-source project "Kyma". This cloud-native solution allows the developers to extend SAP solutions with serverless Functions and combine them with containerized microservices. The offered functionality ensures smooth consumption of SAP and non-SAP applications, running workloads in a highly scalable environment, and building event- and API-based extensions.

During this session, you will learn how to make use of SAP BTP services in the context of a Kyma-based project.

This application will also make use of the services:

- [SAP Launchpad service](https://discovery-center.cloud.sap/serviceCatalog/launchpad-service)
- [SAP HANA Cloud](https://discovery-center.cloud.sap/serviceCatalog/sap-hana-cloud)
- [SAP Alert Notification](https://discovery-center.cloud.sap/serviceCatalog/alert-notification)
- [SAP HTML5 Application Repository](https://discovery-center.cloud.sap/serviceCatalog/html5-application-repository-service)

> ⚠ NOTE: Particularly the enablement of SAP BTP, Kyma runtime and instance creation of SAP HANA Cloud takes around 1 hour. Therefore, it is recommended that you finalize [Getting Started](exercises/ex0/) ahead of time.

The overall solution will finally look like this:

You will also see how to setup your continuous integration and delivery pipeline using "[SAP Continuous Integration and Delivery](https://discovery-center.cloud.sap/serviceCatalog/continuous-integration-&-delivery)" for deploying a CAP application.

## Requirements

To follow the exercises in this repository, you can also use a free SAP BTP trial account or you make use of the free tier inside your SAP BTP global account. Details are described on [SAP.com](https://www.sap.com/products/business-technology-platform/trial.html).

- [jq](https://stedolan.github.io/jq/) - for JSON processing in CLI
- [Docker Desktop](https://www.docker.com/) installed with a valid public account
  > ⚠ NOTE: Be aware of the terms of Docker for usage in enterprises. For details see [link](https://www.docker.com/blog/updating-product-subscriptions/)

> ⚠ NOTE: The various hands-on exercises uses [docker](https://www.docker.com/) and [Kubernetes](https://kubernetes.io/) extensively. A basic knowledge of these technologies will also be helpful.
