Containers have revolutionized the IT world, making it difficult to know where to begin. This course will take you from basics to proficiency step by step.
You’ll start by learning the basics of containers and how they work. Then, you’ll explore key concepts like images and the Docker engine. With the basics out of the way, you’ll learn how to containerize and run an application. After completing this course, you’ll be ready to use Docker in the real world.

Docker Guide for Beginners

Earlier in the chapter, we learned that containers are designed to run a single process, and terminating this process also terminates the container. Let’s test if that’s true. 

Run the following command to start a new interactive container named `ddd-ctr` based on the Ubuntu image, specifying Bash as its main process.


Learn how to manage a container by terminating its main process, restarting the container, attaching to its shell, and exiting the container without stopping it.
