Linux

The code has been tested only on Ubuntu 18.04

Requirements

Client mode local allows you to type commands to request quotes from the server, where docker mode sends one quote and that's it. If you start the application without docker you can specify CLIENT_MODE

export CLIENT_MODE=local

OR

export CLIENT_MODE=docker

Run in docker

1. make build-docker
2. make run-on-docker

Testing

1. Run all tests:

   make test-with-component

2. Run only unit tests:

   make test

Other Makefile commands

1. make start-server
2. make start-client

PoW

I choose to work with CPU-bound function - hashcash. I could find most documentation about this pow scheme and it was perfect for the task requirements.
