Docker is one of the most powerful tools that has enhanced the way we develop, ship, and run applications. In 30 days, learn Docker from being a novice to a pro-level Docker professional, whether you've just started your first steps with Docker or want to extend your Docker knowledge. By the end of this guide, you will be left with in-depth knowledge of Docker, from its basics to advanced topics on your Docker journey. You will also be quite capable of overcoming Docker in a production setup.
Each day, you will discover a new aspect of Docker, with a journey from the very fundamental basics up to more advanced units. You will get your hands dirty as you install Docker, issue commands, work on Docker networking, and more. Resources and links will also be shared to develop a profound understanding of several things.
