Docker Compose

Docker Compose is a tool used to define and run multi-container applications easily. Imagine you have different parts of a service, like a web server, a database, and a caching system; Docker Compose allows you to describe how these parts work together in a simple file. Instead of starting each part manually, you can start them all at once with a single command. This helps developers create, test, and manage applications consistently in different environments, ensuring everything runs smoothly together, just like assembling pieces of a puzzle to create a complete picture.
