Package and run apps in portable containers.
Docker is a containerisation platform available for Windows, Mac, and Linux that packages applications and their dependencies into portable, isolated containers that run consistently across any environment. Docker Compose defines multi-service local development environments with a single YAML file — databases, caches, APIs, and frontends all start with one command. Docker Hub provides a public registry of pre-built images for databases, runtimes, and services. Docker Desktop simplifies container management on developer laptops with a GUI. It is the foundational tool for modern application development and deployment, enabling reproducible builds, environment parity between development and production, and straightforward microservices orchestration.
