Docker in development (Story)
This document is a presentation about Docker given by Quan Nguyen. It discusses how Docker can help with developing microservices applications by allowing different programming languages, libraries, and environments to be containerized. It presents some challenges of developing microservices without Docker, such as configuring different tools. The presentation then demonstrates a sample multi-service web application developed with Docker. It shows how Docker simplifies development, testing, and deployment of the application compared to managing each component separately.

- 22. THE SAMPLE MULTISERVICES WEB APP DockerCoinsMiner is the application for mining DockerCoins. We have 4 services: Random Number (RNG): web service generating random bytes. (Ruby + Sinatra) Hasher: web service computing hash (Python + Flask) Worker: background process using RNG and Hasher (Python) WebUI: web interface to watch progress (NodeJS + ExpressJS + Redis)
- 23. THE SAMPLE MULTISERVICES WEB APP DockerCoinsMiner is the application for mining DockerCoins. How it works: Worker asks to RNG to give it random bytes Worker feeds those random bytes into hasher Each hash starting with 0 is a DockerCoin DockerCoins are stored in Redis Redis is also updated every second to track speed You can see the progress with the WebUI
