Windows Test Image

Hello World:

docker run hello-world:nanoserver

Something more ambition - try run powershell:

docker run -it mcr.microsoft.com/windows/servercore:ltsc2022 powershell

Config

C:\programdata\docker\config\daemon.json

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.

Switch to Windows Containers

& $Env:ProgramFiles\Docker\Docker\DockerCli.exe -SwitchDaemon .

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:

C:\> sc qc docker
