It helps developers move an application between development and deployment environments with a more consistent set of files and runtime requirements. To get started locally, most beginners can use Docker Desktop; Docker Engine is the underlying client-server technology for creating and running containers.
What Docker does
Docker describes itself as an open platform for developing, shipping, and running applications. Instead of installing an application’s components separately in every environment, a developer can package the application and its dependencies into an image. Docker can then run that image as a container.
An image is the packaged template; a container is a runnable instance of that image. Containers isolate applications from one another and from the host, while sharing the host operating system’s kernel. That shared kernel is one reason containers are generally lighter than full virtual machines, which run their own operating system. A container is not a virtual machine, and containerization alone does not make an application secure.
Docker’s glossary defines a container as “a runnable instance of an image.”

Docker’s main components and how they fit together
Docker Engine: the container runtime
Docker Engine creates and runs containers. It uses the Docker daemon (dockerd), a REST API, and the Docker CLI. Common CLI commands include docker run to start a container, docker build to build an image, and docker ps to list running containers.
Docker Desktop: a bundled local development environment
Docker Desktop is an installable environment for Windows, macOS, and Linux. It bundles Docker Engine with related components and a graphical interface, making it a convenient starting point for local development. Docker’s Desktop overview lists components such as Engine, the CLI, Compose, and a Kubernetes cluster.

Docker Compose: a definition for multiple services
Compose describes a multi-container application in a YAML file, conventionally named compose.yaml. It lets you define services—such as an application and its database—and start them together with a command. Compose describes how the services fit together; it does not store or distribute the images.
Docker Hub: a registry for images
Docker Hub is Docker’s public registry service for storing, sharing, and managing images. Developers can retrieve images from it or publish images there. In short, Compose describes an application’s services, while Hub is one place to obtain or share the images those services use.

Docker Desktop or Docker Engine?
Choose based on your operating system and whether you want a bundled desktop development environment or the Engine installation by itself.
| Option | Best fit | What to know |
|---|---|---|
| Docker Desktop | Local development, especially for beginners who want a GUI and bundled tools | Available for Mac, Windows, and Linux. Its platform-specific behavior and licensing terms matter; see the Desktop overview and the relevant setup guide. |
| Docker Engine | Linux hosts or users who specifically need Engine and the CLI without Desktop’s bundled environment | Installed through a separate, distribution-specific route. Engine is open-source software; Docker Desktop has separate subscription terms. |
Docker’s Get Docker guide links to Desktop for Mac, Windows, and Linux, as well as a separate Engine installation path. On Linux, Desktop runs in a VM with its own desktop-linux context and separate image and container storage. Existing containers and images in a Linux Engine are not available in Desktop by default, and running both can create port conflicts; consult Docker’s Linux installation guide before choosing a setup.

How to choose and install a Docker setup
- Choose the component. For a local development environment with a GUI and bundled tools, start with Docker Desktop. If you need only Engine on a Linux host, use Docker’s Engine installation guide for your distribution.
- Check your platform’s requirements. For Windows, Docker Desktop supports WSL 2, Hyper-V, and Docker VMM (Beta), with WSL 2 the default for most users according to the current Windows installation and requirements guide. Requirements vary by version. Windows containers require Windows Pro or Enterprise, and Windows Server is not supported for Docker Desktop.
- Use the official installation route. Start at Docker’s Get Docker page and follow the instructions for your operating system or Engine distribution.
- Check which environment you’re using. This is particularly important on Linux, where Desktop and a pre-existing Engine can have distinct contexts and storage. Docker’s Linux guide explains the
desktop-linuxcontext.
Docker Desktop licensing and cost
Docker Engine and Docker Desktop have different licensing contexts. Docker says Engine is accessible to all, while Desktop use is governed by separate subscription terms. As described in Docker’s Plans FAQs and the Windows installation guide, Docker Desktop is free for personal use, education, non-commercial open-source projects, and commercial use by a business with fewer than 250 employees and less than $10 million in annual revenue. Both business conditions must be met for that small-business exception. A paid subscription is required outside those commercial eligibility limits and for government entities. Review the current terms for your situation before installing it for work.
Docker’s pricing page, accessed October 4, 2026, lists Docker Pro at $11 per user per month when billed monthly or $9 per user per month when billed annually; Team at $16 monthly or $15 annually; and Business at $24 annually per user, with no monthly self-service price shown in the comparison. These are listed plan prices, not a determination of which subscription a particular organization needs. Compare current plan features and terms on Docker’s pricing page.

Docker Hub pull limits to consider
Docker’s Plans FAQs state that authenticated Docker Personal users have a limit of 100 image pulls per hour, while unauthenticated users have a limit of 10 pulls per hour per IP address; paid plans have no hourly pull limit. These service limits can affect automated builds or teams that retrieve many images. Check Docker’s current FAQ before relying on them, because limits can change.
