The Docker Handbook

The concept of containerization itself is pretty old, but the emergence of the Docker Engine in 2013 has made it much easier to containerize your applications.

According to the Stack Overflow Developer Survey - 2020, Docker is the #1 most wanted platform, #2 most loved platform, and also the #3 most popular platform.

As in-demand as it may be, getting started can seem a bit intimidating at first. So in this article, we'll be learning everything from basic to intermediate level of containerization. After going through the entire article, you should be able to:

  • Containerize (almost) any application
  • Upload custom Docker Images to online registries
  • Work with multiple containers using Docker Compose


  • Familiarity with the Linux Terminal
  • Familiarity with JavaScript (some later projects use JavaScript)
