No I don't want to ;-)

You probably meant to say that you wanted to check that?

I do not think that there is one official Git image. You also have to be
more precise than that: do you mean a Linux-based image or a Windows-based
one?

As far as a Docker image with Git in it: I do not think that this image
itself would be useful. So you can fetch Git repositories? What then?

What most developers do who need Git in their Docker image is to start
with the other requirements: typically a toolchain such as GCC. Or even a
stack such as LAMP or MEAN.

Personally, I use Docker images as base for the build agents used to
perform a few tasks in the Git for Windows project, so they start with the
bare-bones Windows image, add the Visual Studio Team Services build agent,
and then take things from there.

So essentially, I do not think that having a base image just with Git
would be useful. It is much more useful to *add* Git to other base images,
and that is easily done:

Linux (Ubuntu/Debian):

	sudo apt-get install git


Windows:

	$Version = "2.14.3"
	$Base = "https://github.com/git-for-windows/git/releases/download/v"
	$Url = $Base + $Version + "MinGit-" + $Version + "-64-bit.zip"
	$Path = "$HOME\Downloads\MinGit.zip"
	$Dir = "$HOME\MinGit"
	$WebClient = New-Object System.Net.WebClient
	$WebClient.DownloadFile($Url, $Path)
	Add-Type -AssemblyName System.IO.Compression.FileSystem
	[System.IO.Compression.ZipFile]::ExtractToDirectory($Path, $Dir)
