:ship:Docker consists of three main components: Docker client, Docker demon, and Docker registries.
:construction_worker:The Docker client is the primary interface for managing Docker objects like images and containers.
:gear:The Docker demon is the core engine that handles container operations and can utilize OCI-compliant runtimes.
:globe_with_meridians:Docker registries, such as Docker Hub, store and distribute container images.
:bulb:Docker popularized containerization and introduced key concepts like standard image format, image building, image sharing, and container running.
