Cannot run lando inside a Windows Docker image

[gpetrounrt]

I am currently trying to run lando inside a Windows Docker image on Windows OS. Specifically, I am using docker:20.10.8-windowsservercore-1809 from the official Docker in Docker website.

If I use the following Dockerfile, everything works when building by executing docker build -f Dockerfile -t lando-test .

FROM docker:20.10.8-windowsservercore-1809
SHELL ["powershell"]

ARG LANDO_VERSION=3.4.0

WORKDIR /app

RUN $landoUri = \"https://github.com/lando/cli/releases/download/v{0}/lando-win-x64-v{0}.exe\" -f $env:LANDO_VERSION; \
    $landoDestinationDirectory = ($pwd).Path + \"\\lando-cli\"; \
    $landoDestinationPath = $landoDestinationDirectory + \"\\lando.exe\"; \
    $env:Path += \";\" + $landoDestinationDirectory; \
    [Environment]::SetEnvironmentVariable('PATH', $env:Path, [EnvironmentVariableTarget]::Machine); \
    New-Item -Path $landoDestinationDirectory -ItemType Directory; \
    Invoke-WebRequest -Uri $landoUri -OutFile $landoDestinationPath

RUN lando version

However, when I try to run the image by executing docker run -i --name lando-test -v //./pipe/docker_engine://./pipe/docker_engine lando-test I observe the following when executing commands inside the image:

docker run hello-world works just fine and gives the expected output. lando version works just fine and gives the expected output. lando init throws the following error: Lando could not detect an installation of Docker, which is a required dependency

Looking at the daemon code and env code in GitHub, I see that the path to Docker is somehow hardcoded and does not match the path from the official Docker in Docker image which is C:\Program Files\docker\docker.exe. I guess that there are similar hardcoded paths in other places.

1. Would it be possible to somehow add the ability to configure the paths in question?
2. Is there already a way I could achieve this?

Apparently, I can use the following lines in the Dockerfile

RUN [Environment]::SetEnvironmentVariable('LANDO_DOCKER_BIN', \"C:\Program Files\docker\docker.exe\", [EnvironmentVariableTarget]::Machine)
RUN [Environment]::SetEnvironmentVariable('LANDO_DOCKER_BIN_DIR', \"C:\Program Files\docker\", [EnvironmentVariableTarget]::Machine)

I now see the following more mysterious error:

Perhaps there is another setting that I need to change?
