Docker A Step-By-Step Guide To Know Everything You Need About Containerizing Your Applications And Running Them In Production

At the heart of the containerization craze is Docker, the one PaaS (Platform as a Service) system that's proving a game-changer in the creation, deployment and running of applications using containers!

Why is that so, you might wonder?

Well, Docker makes the whole process easier and faster, thanks to the fact that it allows developers to package applications with all the parts they need like libraries and other dependencies before deploying everything as one package. And with that, developers are assured that the applications they create will run on any other machine, irrespective of the customized settings that the machines might have that may be different from the machine that was used to write and test the code.

Just imagine the level of possibilities, freedom and speed that this can give you as an avid developer or systems administrator....

Indeed, Docker is a permanent solution to the slowness and complexity associated with the deployment and running of applications using containers!

And this book is about to teach you the basics of Docker, right from the fundamentals of containers with a beginner end-user in mind so that you understand, in a few words:

• How this tool can reduce infrastructure resources to drive down company costs while increasing profits (if you're adopting it for your company)
• How it ensures consistency across multiple development and release cycles to enable more efficient analysis and fixing of bugs (if you're an IT professional looking to make your work easier)

...Among so many other features.

Even if this is the first time you are coming across the word "Docker" and have such questions like...

What exactly is Docker and how is it different from anything you've come across before?

Where do you start in your journey to learning how to master Docker?

How do you start using Docker for the very first time?

What are the dos and don'ts to using Docker?

How do you bring out your A-game as a Docker user?

And many others are going through your mind, you are in luck because this book will teach you all that and much more.
