Docker Desktop

ApplicationDocker Inc.

Also called docker desktop for windows, docker

Docker Inc.Productivity

Docker's Windows GUI and engine for containers. The window is Docker Desktop.exe. WSL 2 is a backend it can use. Installing WSL alone is not this product.

What you need to know

Docker Desktop is not WSL by itself.

Docker Desktop is Docker Inc.'s Windows app. It can use WSL 2, Hyper-V, or Docker VMM as a backend. wsl.exe is Microsoft's Linux layer. Installing Ubuntu in WSL does not install Docker Desktop.exe.

What is it?: A container GUI plus engine
Is WSL enough?: No. WSL is a backend, not Desktop
Needs virtualization?: Yes. Docker lists SLAT and 8 GB RAM

Feex says

If Docker Desktop will not start, I would check virtualization and the WSL version Docker documents. I would not treat a working Ubuntu prompt as proof that Docker Desktop is installed.

What is Docker Desktop?

Docker Desktop is the Windows GUI, Linux VM or WSL backend, and docker CLI integration from Docker Inc. It is not the WSL distro you already installed for school.

If you have never used it

If a tutorial said install Docker, on Windows that usually means Docker Desktop from docker.com. You still need virtualization on. WSL 2 is the common backend. A working wsl prompt is not the same as Docker Desktop.exe in the tray. License terms depend on company size.

What is it used for?

Run containers on Windows

Images and compose stacks start through Desktop. That is not a bare wsl --install.

docker and compose CLIs

The CLIs talk to the Desktop engine. A docker binary only inside Ubuntu is a different install.

Pick a backend

WSL 2 is the default for many PCs. Hyper-V needs an all-users install. Neither backend is WSL alone.

Who is it for?

Developers whose README assumes docker compose
People who enabled WSL and wondered why docker was not a command
Shops that must check Docker Desktop licensing

Current status

Docker Desktop (2016) is a current containers from Docker Inc.. The vendor still points Windows users at https://www.docker.com/products/docker-desktop/.

How old is it?

Docker Desktop for Windows arrived in 2016 after Docker Toolbox and VirtualBox workarounds. Current Desktop expects a recent Windows 10 or 11 build and a current WSL. It is not the 2014 boot2docker days.

Versions

Major channels first. Exact build numbers are not all verified here.

WSL 2 backend

Hyper-V backend

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	Docker documents recent 64-bit Windows 10 (22H2 class) or Windows 11 builds
RAM	8 GB system RAM listed for the WSL 2 backend, per Docker

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
Docker Desktop.exe	Tray and dashboard
com.docker.backend.exe	Engine helper on many installs

Startup components

Docker Desktop can start with Windows from its own setting. That starts the engine VM, not a Microsoft service named Docker.

File locations

Common Docker Desktop locations
Typical install	C:\Program Files\Docker\Docker\

File formats

DockerfileCompose YAML

Common problems

WSL works, docker does not

Ubuntu in WSL is not Docker Desktop. Install Desktop from docker.com, then enable the WSL 2 based engine in its settings.

Virtualization off in firmware

Docker documents VT-x or AMD-V. A Hyper-V checkbox cannot fix firmware that disabled virtualization.

Getting unstuck

Confirm Docker Desktop is installed, not only WSL

Start menu should show Docker Desktop. wsl -l -v names distros. Those are not the same product.

Check WSL version against Docker's floor

Docker asks for WSL 2.1.5 or later for the WSL 2 backend. wsl --version is the check.

Read the installer docs for backend and license

Per-user installs cannot use Hyper-V. Company size can require a paid subscription.

Alternatives

Podman Desktop and a Linux Docker Engine overlap. Pick them for license or workflow, not because WSL already had a penguin icon.

Related hardware

Virtualization, 8 GB RAM, and an SSD matter more than a gaming GPU. Images want disk.
