Git in docker container.

[greenfox1505]

I believe Git just be installed by default in the docker container. Git integration is a core feature of VSCode. It's easy to add apt-get install git without significant complication or inflation of the docker image.

actually there's some inflation but its not detriminal as git itself is very lightweight.

[greenfox1505]

IMHO it's not significant inflation.

Maybe it would be a good idea for future additions to add a bare bone image for people like me that wan't to save drive space and a more featured image.
If we base the more featured image on the barer one we could make the building process really easy.
