Quarkus Microservices with Consul Discovery Demo Project

In this project I'm demonstrating you the most interesting features of Quarkus Project for building microservice-based architecture.

Getting Started

Currently you may find here some examples of microservices implementation using different projects from Quarkus. Here's a full list of available examples in this repository:

1. Using Quarkus for building microservices that may be easily deployed outside Kubernetes. Integrating Quarkus with Consul discovery and KV store. The example is available in the branch master. A detailed guide may be find in the following article: Detailed description can be found here: Quarkus Microservices with Consul Discovery

Usage

1. Maven 3.6.3+
2. JDK 11+
3. Docker - run Consul:
   $ docker run -d --name=consul -e CONSUL_BIND_INTERFACE=eth0 -p 8500:8500 consul
4. Run applications: $ mvn compile quarkus:dev

Architecture

Our sample microservices-based system consists of the following modules:

• gateway-service - a module that uses Spring Cloud Gateway for running Spring Boot application that acts as a proxy/gateway in our architecture.
• employee-service - a module containing the first of our sample microservices that allows to perform CRUD operation on in-memory repository of employees
• department-service - a module containing the second of our sample microservices that allows to perform CRUD operation on in-memory repository of departments. It communicates with employee-service.
• organization-service - a module containing the third of our sample microservices that allows to perform CRUD operation on in-memory repository of organizations. It communicates with both employee-service and department-service.

The following picture illustrates the architecture described above.
