A tool that packages your app and its dependencies into a portable container that runs the same everywhere.
Docker is containerization technology. It packages your app, runtime, libraries, and configuration into a container — a standardized unit that runs identically on any machine. Instead of "works on my machine" problems, everyone runs the same container.
You define a Dockerfile describing your app's environment, then Docker builds an image from it. Running that image creates a container. Docker uses the CLI — commands like docker build, docker run, and docker compose manage your containers.
Docker is essential for deploying to cloud platforms, running databases locally, and ensuring consistent development environments. Edge Functions on Supabase run in containers. Claude Code can write Dockerfiles and docker-compose configurations for your projects.
A Dockerfile provides the instructions for building a Docker container image, specifying the base system, code, dependencies, and startup command.
