Docker is a powerful platform that operates on a client-server architecture, where the client and server communicate over a RESTful API. The client acts as an interface, allowing users to interact with Docker using commands to build, run, and manage Docker containers. Meanwhile, the server component, known as the Docker Engine, executes these commands in the background. This architecture enables Docker to be flexible and efficient, making it capable of running containers across different environments. With Docker, building and running containers has never been easier!
