What is Docker?
Docker is a containerization platform that allows developers to package applications and their dependencies into lightweight, portable containers that run consistently across any environment. It solves the classic 'it works on my machine' problem by ensuring that software behaves the same way in development, staging, and production. Docker is used by individual developers, DevOps teams, and enterprises alike to simplify application deployment, improve resource efficiency compared to traditional virtual machines, and accelerate CI/CD pipelines. Its massive ecosystem, including Docker Hub's public image registry, makes it a foundational tool in modern software development.
