docker run --detach IMAGE Detached mode, shown by the option --detach or -d, means that a Docker container runs in the background of your terminal. It does not receive input or display output. If you run containers in the background, you find out their details and then reattach your terminal to its input and output.

This tutorial is aimed at beginners. I will show you how to run containers in detached mode. Then reconnect them to your terminal input and output if needed.
