Install Docker Community Edition
Docker Community Edition (CE) provides a standard runtime environment for containers with a common API and command-line interface (CLI). It is managed by the open source community as part of the Moby Project.

Container Desktop
container-desktop https://container-desktop.io/
Container Desktop is an open-source alternative to Docker Desktop. It enables you to build, push, pull and run Linux containers on Microsoft Windows, by providing a seamless integration with Docker Engine Community Edition running on Windows Subsystem for Linux. The Container Desktop bundles the open-source docker and docker-compose cli clients for a native and simple user experience.
Why Container Desktop?¶
- Free and open-source;
- Easy and hassle free installation experience;
- Plain and simple, no unnecessary bells and whistles;

Stevedore Linux Container Support
Back in summer 2021, when this project was started, there were no known alternatives to Docker Desktop. Container Desktop didn’t exist yet, and Rancher Desktop just released initial 0.1.0 release.
Today, things are very different. Rancher Desktop provides both Docker and Kubernetes support, with a very advanced UI. Stevedore is very unlikely to even come closer to Rancher Desktop functionality due to limited developer resources and lack of motivation.
Thus, starting with 0.10.0 release, Stevedore focuses on its primary goal - providing a convenient way to install Docker for Windows containers.
If you want to run Linux containers, consider one of these projects:
- Rancher Desktop (Windows + Linux + Mac) - https://rancherdesktop.io/
- Container Desktop (Windows-only) - https://container-desktop.io/
- Colima (Mac-only) - https://github.com/abiosoft/colima

Isolation
Configure container isolation technology (Windows) https://docs.docker.com/reference/cli/dockerd/#configure-container-isolation-technology-windows
For Windows containers, you can specify the default container isolation technology to use, using the --exec-opt isolation flag.
The following example makes hyperv the default isolation technology:
dockerd --exec-opt isolation=hyperv dockerd --exec-opt isolation=process
If no isolation value is specified on daemon start, on Windows client, the default is hyperv, and on Windows server, the default is process.
Isolation
Windows Server Containers use Hyper-V isolation by default on Windows 10 and 11 to provide developers with the same kernel version and configuration that will be used in production.

Service
See service:
sc qc docker
Service is running as: docker
C:\WINDOWS\system32\dockerd.exe --run-service --service-name docker
Add a Docker Group to allow normal users to manage docker: (run as administrator)
net localgroup docker-users /add
Add user to group:
net localgroup docker-users [USER] /add
Update service to use docker-users group:
# -G, --group string Group for the unix socket (default "docker") sc config docker binPath="C:\WINDOWS\system32\dockerd.exe --run-service --service-name docker -G docker-users"
sc config docker binPath="C:\Windows\System32\dockerd.exe --run-service --config-file=C:\ProgramData\docker\config\daemon.json"
Restart service:
net stop docker net start docker
