Docker is an open-source platform for containerising applications. A Docker container packages application code, runtime environment, libraries, and configuration into an isolated, self-contained unit that runs identically regardless of the underlying operating system. This solves the classic problem of 'it works on my machine' - a container that works locally also works in test environments and production. Docker is the foundation of modern cloud-native architecture: KubernetesOpen source container orchestration platform - automates deployment, scaling and management of containerised applications. orchestrates Docker containers at scale.

Docker Hub is the central registry for public and private container images.
