The goal of this project is to learn how to build microservice-based applications. I opted for Java due to the rich ecosystem offered by Spring. For this project I followed the book Spring Microservices in Action.
Below you'll find a listing of all the directories / services and what they do:
| Service | Description |
|---|---|
| common | Shared library used by all the microservices for infrastructure-style code. |
| configserver | The configuration server uses Spring Cloud Config to provide externalized configuration in the distributed system of microservices. |
| config | Contains all the configuration files used by the configserver. |
| eurekaserver | This service allows for Service Registration and Discovery using Netflix Eureka. |
| licenses | This service manages licenses of various organizations. It communicates with the organization service to obtain data from the organizations. |
| organizations | This service manages all the organizations. |
| zuulserver | This service acts as a API Gateway using Netflix Zuul. Zuul interacts with the Eureka server to discover services in the distributed system. It's also the place where cross-cutting concerns are organized, such as setting correlation ID's for distributed tracing and authentication. |
| authentication | This service is responsible for authentication and authorization of users using Oauth2. |
| zipkinserver | Provides a Zipkin service for distributed tracing together with Spring Cloud Sleuth |
To run all of the services create a package for each of them and then run:
$ docker-compose up -dI've used Confluent's images for their Kafka platform. You can access the Control Panel to manage your Kafka clusters by navigating to http://0.0.0.0:9021.
