Master Microservices with Spring Boot and Spring Cloud - Step 04 – Playing with Docker Images and Containers

This video tutorial covers the basics of managing Docker containers and images. It explains how to stop a running application using control C and introduces the concept of running containers in detached mode to keep them running in the background. The tutorial also demonstrates how to view and follow container logs, manage multiple containers from the same image, and view all images and containers on a machine. Finally, it shows how to stop running containers and view their status.

What is the purpose of running a Docker container in detached mode?
