GO SERVICES

This is an attempt to setup 3 go services and a RabbitMQ connection in a docker environment.

User Service

The User Service is a simple service that returns a user object based on specified user IDs. The service also simulates some delays and faults that should be handled in the order service.

Product Service

The Product service is another simple service with three fixed products that are retrieved by their product codes. This service also some delays and faults

Order Service

The Order Service is a more extensive service the receives a POST request containing a user ID and product code, fetches the corresponding data from the user and product services, saves the order, and then publishes a message to RabbitMQ. Sample create order request body:

{
    "user_id": "e6f24d7d1c7e",
    "product_code": "product1"
}

Setup Guide

Requirements

• Docker

Instructions

1. Clone the repo and in each service, make a copy of .env.sample as .env and update the environment variables as you deem fit

git clone https://github.com/mhope-2/go-services.git
cp .env.sample .env

2. Start the services in a docker environment

docker-compose up

or

make up

Running Tests

For the user and product services:

go test -v -cover ./...

For the order service, since the dependencies (Postgres and RabbitMQ) aren't completely isolated in the tests as disposable docker containers, you'll have to keep them up before running the test command
