Docker Command Line How To Run Docker

Youll learn how to run Docker containers in the background or foreground, and switch between the two; how to publish ports; how to connect a database app and a web app running in separate containers; and how to share directories between containers and your Mac and among containers.

Containers provide isolation and security like virtual machines, but theyre much smaller because they run in the host machines system.

Basically, to join the ranks of it-works-on-my-machine developers.

After completing this tutorial, youll be well on your way to Docker ninjadom.

You can run the same image in multiple containers using very little memory.
