Introduction

Docker is a technology that is currently popular with startups. With Docker, we containerize the application that we are going to build. With container technology, our application will have portability, maximum performance and make it easier to update.

What I mean by containerization is when you create an application, you build everything your application needs, such as a Web Server, Database, etc. so that when in Production the application that you deploy on Docker will be the same as on your Local/Laptop without reconfiguring the WebServer.
