Refinitiv Assignment

This repository is for an assigment given by the Refinitiv devops crew.

This repository contains a python flask application and an nginx configuration as a load balancer.

Architecture

A user sends an HTTP request for the exposed address of nginx with the uri /api/ip to receive the ip address from one of the applications.
The nginx load balancer will forward the request to one of the application written in the configuration file in a round-robin fashion.
When an application receives the request, It will return a json with the requested data. Exmaple:
```
{
  "ip-address" : "172.17.0.3"
}
```

Getting Started

To deploy the environment, there is a shell script in the main repository directory named deploy_refinitiv_app.sh. You need to run it as root in order to deploy docker containers.

How to test

To test the environment, there are two options:

Use the test_refinitiv_app.sh shell script to test the results returned from the applications.
Open up a web browser and go to http://localhost:8080/. This will open the main page of an application with a simple explanation on how to use it.
