Is it possible to create custom Linux-based Docker image on Azure Windows Server DSVM

I am using an Azure DSVM in a DevTest Lab running Windows Server 2019. I am trying to get Docker installed and working to allow me to run local experiments from Azure ML Service environments.

I want to build a custom Linux container on Docker - which I believe is possible on Windows from reading some other online posts (I can't use a Linux host for various reasons). When I try to create such an image that contains a WORKDIR ... step, I get a "container ***** encountered an error during CreateProcess: failure in a Windows system call" error.

I installed Docker on the DSVM (which is a Standard D2s_v3) by adding the "Docker" artifact at creation and then running the following commands to enable Linux containers:

$> Install-WindowsFeature -Name Hyper-V -IncludeManagementTools -Restart
$> [Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine")

Running a simple Linux container works fine:

$> docker run --rm -it alpine:latest
/ # ls
bin    dev    etc    home   lib    media  mnt    opt    proc   root   run    sbin   srv    sys    tmp    usr    var
/ #

To build a custom image, I'm using a simple Dockerfile as follows:

FROM alpine:latest

WORKDIR /abm

The image appears to build successfully:

$> docker build --no-cache -t abm-alpine:workdir -f .\abm-alpine.Dockerfile .

When I run the image, I get the following error:

$> docker run --rm -it abm-alpine:workdir

I've tried various logs (e.g. Get-WinEvent -LogName Microsoft-Windows-Hyper-V-Compute-Operational and Get-EventLog -LogName Application -Source Docker) but cannot see any additional information about the error.

Can anyone advise if it is possible to create custom Linux-based images on a Windows DSVM? If it is, can anyone advise what the problem may be or any additional troubleshooting steps I could take?

Thanks!

It is possible to create Linux container on Windows Server.

Although this is currently in experimental stage.
