Docker

Docker is a software platform that enables developers to build, package, and run applications inside lightweight, portable containers. It provides tools such as Docker Desktop, Docker Engine, Docker Compose, and Docker Hub to support the entire container lifecycle, from local development to image distribution. The platform is used by individual developers, engineering teams, and enterprises to standardize application environments across different operating systems and infrastructure. Docker's core value lies in solving the "it works on my machine" problem by isolating application dependencies into consistent, reproducible containers. It also supports collaboration through shared image registries and integrates with CI/CD pipelines, orchestration systems like Kubernetes, and cloud deployment workflows.
