Installation

Using docker-compose

The easiest (and preferred) way to run this application is via docker-compose:

Create a file named .env at the root directory of the project. The .env.template file contains all supported configuration options, so you can just copy-paste it and adjust the parameters as you see fit
Run docker-compose up --build

Using docker without docker-compose

If you don't feel like installing docker-compose, you can manually run all needed containers. There is a Dockerfile for each microservice under their respective root directories, and you'll also need to run RabbitMQ and PostgreSQL either by installing them locally or running their docker containers. Don't forget to provide environment variables to your containers.

Without docker

cd registry && mvn clean package to build the registry microservice
cd db && mvn clean package to build the db microservice
Run RabbitMQ and PostgreSQL
java -jar registry/target/registry-1.0-SNAPSHOT.jar
java -jar db/target/db-1.0-SNAPSHOT.jar

The REST API should be available at port 8080.

Usage

The REST API provides two endpoints:

GET /user/{id} returns the user with the specified ID, or 404 if there is no such user
POST /user creates a new user with the data in the request body and returns the newly created user, or 403 if the data provided is invalid

A user entity has the following format:

{
  id: number,
  login: string,
  password: string,
  name: string,
  surname: string,
  email: string,
  creationDate: string
}

User creation request body should be of the following format:

{
  login: string,
  password: string,
  name: string,
  surname: string,
  email: string
}

The id and creationDate fields will be populated by the database.
