Cloud Native Workshop

Overview

This one day hands-on cloud-native workshops provides developers and introduction to cloud-natives applications and gives them an experience of building cloud-native applications using OpenShift, Eclipse Che7, Spring Boot, Quarkus, Vert.x and more.

During the various steps of the the workshop you will use CodeReady Workspaces, an online IDE that is running on Red Hat OpenShift to write, test and deploy these services:

Catalog Service exposes using a REST API content of a catalog stored in a relational database
Inventory Service exposes using a REST API the inventory stored in a relational database
Gateway Service calls the Catalog Service and Inventory Service in an efficient way
WebUI Service calls Gateway Service to retrieve all the informations.

The outcome is an online store with a catalog of product items and an inventory of stock:

In addition to the application code, you will learn how to deploy the various services to OpenShift and how to use it to route the trafic to these services and monitor them.

You will also have the opportunity to look at some optional steps such as debugging, continuous delivery, externalized configuration and more.

Let's start the workshop with the discovery of OpenShift and CodeReady Workspaces.
