About
Docker is a containerization platform that packages applications with all their dependencies—libraries, system tools, code, and runtime—into standardized units called containers. Developers use Docker to build, test, and deploy applications quickly across any environment while ensuring code runs consistently. Containers enable rapid scaling and simplify deployment workflows by eliminating environment-specific configuration issues.
