Docker

Docker is an open-source platform that enables developers to automate the deployment, scaling, and management of applications within lightweight, portable containers. These containers package an application along with its dependencies and environment, ensuring consistency across different computing environments. By using Docker, applications can run seamlessly on any system that has Docker installed, reducing the "works on my machine" problem. Docker uses a client-server architecture and provides a command-line interface as well as a graphical user interface for managing containers. It is widely used in software development and deployment processes, particularly in cloud computing and microservices architectures.
