Introduction

This is the eclipse project for some simple stateless apps

Getting Started

There are three Eclipse projects in this repo

StatelessYaml - contains the YAML files and also example configs to use for deployments. Please look at the README.md file in that project for instructions on how to install and run these stateless applications in Kubrnetes

StatelessFront - a very simple application based on the front ent part of the Helidon example "Greeting" application (/greet). This only does the front end processing, it communiucates to the StatelessBack application to get the prefix used byt the greeting.

StatelessBack - a very simple application based on the back end (Greeting provider code) of the Helidon example "Greeting" application (/prefix). This only supports the retrieval and setting of the prefix.

Using two separate microservices is of course a completely artificial split but is intended to enable the exploration of in Kubernetes communications.

Both of the "Front" and "Back" applications also provide /openapi, /metrics, and /health endpoints. They also provide mechanisms to simulate fault conditions.

Prerequisites

You will need Maven (3.8.5 works, earlier may not) and Java 17
