This document specifies guideines to start stemcell-GO which is a basic server application. 

The intent of this repository is to provide a basic framework to write GO server application which only requires to replace business logic.


The project spawns 2 microservices:
1. PostgreSQL - database for data storage
2. Hornet - web server for CRUD operations


Pre-requisites:
1. Internet connection to download dependencies.


To start the server-
1. on Ubuntu machine, run script "run-ubuntu.sh"
2. for other OSs, run below command from the project directory where docker-compose.yml is present:
	docker-compose up -d 
NOTE: On host machines with OSs other then Ubuntu, docker and docker-compose utility must be already installed on it.


To interact with the server-
1. get server host IP of the machine running the microservices:
	 ifconfig|less
2. The server listens on port 8080. One can send request using curl or Postman.
	ex: curl -k http://localhost:8080/api/resource/


The server exposes 5 API endpoints:
1. POST /api/resource - Create a new resource
2. GET /api/resource/{id} - Get a specific resource by ID
3. PUT /api/resource/{id} - Update an existing resource by ID
4. DELETE /api/resource/{id} - Delete a resource by ID
5. GET /api/resource/ - List all resources


The payload request of API endpoint is a string which will be stored into DB alongwith an ID field that will be the primary key:
ex:
{
	"payload": <string>
}




The ansible-playbook directory contains playbooks to deploy a running stemcell-GO server on a EC2 instance. Refer to its README.txt for more info.


The exposed endpoints can be tested via importing postman collection provided in test/postman-collections directory.
