Docker Toolbox enables Docker to run on older Mac or Windows operating systems Available for both macOS and Windows, however functionality of Docker Toolbox has been superseded by Docker for Mac and Docker for Windows on newer platforms toolbox01.png Consists of a set of apps and a virtualization platform Docker Engine - consisting of Docker daemon, client, API Docker Machine - enables Docker to be used on non-Linux machines such as Windows and macOS Docker Compose - manage multi-container application; manage multiple containers as one Docker Kitematic - Docker GUI shell  - preconfigured for a Docker command-line environment VirtualBox - lightweight virtualization solution References: Docker Toolbox Overview Licensed under a Creative Commons Attribution 4.0 International License .

Docker client The Docker client, in the form of the docker binary, is the primary user interface to Docker accepts commands and configuration flags from the user and communicates with a Docker daemon Image: https://docs.docker.com/engine/understanding-docker/ One client can communicate with multiple local or remote daemons Other tools include: docker, docker-machine, docker-compose Licensed under a Creative Commons Attribution 4.0 International License .

Docker daemon creates and manages Docker objects, such as images, containers, networks, and data volumes subset of the Docker Engine background service running on the host that manages building, running and distributing containers The Docker client and daemon communicate using a REST API, over UNIX sockets or a network interface Image: https://docs.docker.com/engine/understanding-docker/ Licensed under a Creative Commons Attribution 4.0 International License .

Docker Engine is a client-server application with these major components: A server called a Docker daemon A REST API which specifies interfaces for programs to talk to the daemon A command line interface (CLI) client interacts with the Docker daemon through scripting or CLI commands. Manages (builds, ships and runs) Docker containers deployable on a physical or virtual host, locally, at the datacenter or in the cloud. sets up the management environment for containers Image: https://docs.docker.com/engine/understanding-docker/ conceptually similar to a hypervisor in that it creates a virtualized environment and facilitates access to system resources docker Engine is supported on Linux, Cloud, Windows, and macOS Reference: Installation instructions: https://docs.docker.com/engine/installation/ Licensed under a Cr

Docker Host A Docker Host is the server running Docker engine and able to host containers . A Docker Host is a Linux server with Docker installed or a newer model MacOS or Windows server with Docker for Mac or Windows installed. The docker-machine command can be used to create and manage Docker Hosts on older Mac or Windows servers or to create additional Docker Hosts on Linux servers. Docker Host runs Docker Engine, which consists of a Docker daemon, a REST API and a set of client CLI tools Docker Engine runs natively on Linux systems and can provision multiple Docker hosts locally, on a network, or in the cloud. You can use the docker-machine command line tool to manage (create, start, inspect, stop, restart) a Docker host, locally, remotely over the network or in the cloud Examples of a Docker Host operating systems: Linux system with Docker installed and running
