This question already has an answer here:
I already created a repository. Can I make it a bare type or shall I start over?
Jørn Schou-Rode
According to the FAQ, conversion from non-bare to bare can be done in two ways. The best one:
$ git clone --bare -l repo repo.git
$ rm -rf repo
To create a bare repository from scratch:
$ mkdir repo.git
$ cd repo.git
$ git --bare init

Just move the .git folder away from the working copy.
mv /var/git/repo/repo/.git /var/git/repos/repo.git
You might want to follow that up with a
git config --bool core.bare true
in that repository, just in case git complains about something not being right.
git clone --bare repo
This will give you a new bare version of repo named repo.git. Easy, no?
