Dockerized Full-Stack Environment

Introduction

This tutorial will teach you how to setup a dockerized environment that with a single command can run:

• a MySQL database server (and create and populate a database in it in the first run)
• a back-end using the NestJS framework with a simple API
• a front-end using the NextJS framework that calls the back-end API
