Cannot update PATH variable in a windows docker container

ENV is not going to work on Windows. You have to do this (see the linked-to Dockerfile):

	$env:PATH = 'C:\git\cmd;C:\git\mingw64\bin;C:\git\usr\bin;' + $env:PATH; \
[Environment]::SetEnvironmentVariable('PATH', $env:PATH, [EnvironmentVariableTarget]::Machine); \
