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.

Install Docker Server Edition
Just like Community Edition, but allows for Linux containers
Enable containers:
Enable-WindowsOptionalFeature -Online -FeatureName Containers
Reboot:
Restart-Computer -Force
Install Docker:
Install-Module -Name DockerMsftProvider -Repository PSGallery -Force
Install-Package -Name docker -ProviderName DockerMsftProvider
Restart:
Restart-Computer -Force
Start service:
Start-Service Docker
Stop-Service Docker
Get-Service docker
Server core:
# 2022 docker pull mcr.microsoft.com/windows/servercore:ltsc2022
# 2019 docker pull mcr.microsoft.com/windows/servercore:ltsc2019
Run Linux Containers (Nested):
Get-VM WinContainerHost | Set-VMProcessor -ExposeVirtualizationExtensions $true
[Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine")
Restart-Service docker
daemon.conf:
$configfile = @”
{
“experimental”: true
}
“@
$configfile|Out-File -FilePath C:\ProgramData\docker\config\daemon.json -Encoding ascii -Force
LCOW:
Invoke-WebRequest -Uri "https://github.com/linuxkit/lcow/releases/download/v4.14.35-v0.3.9/release.zip" -UseBasicParsing -OutFile release.zip Expand-Archive release.zip -DestinationPath "$Env:ProgramFiles\Linux Containers\."
Run ubuntu:
docker run -it --rm ubuntu /bin/bash
Switch back to Windows Containers:

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
See updated service:

What is Moby? Moby is an open framework created by Docker to assemble specialized container systems without reinventing the wheel. It provides a “lego set” of dozens of standard components and a framework for assembling them into custom platforms.
