mkdir repo.git
git --git-dir=repo.git init %%--%%bare

git init --bare --shared=group repo_path
chgrp -R foo repo_path

mv repo/.git repo.git
git --git-dir=repo.git config core.bare true
rm -rf repo

git clone --bare repo_path bare_repo_path

git clone --mirror repo_path bare_repo_path

Set up a mirror of the source repository. This implies --bare. Compared to --bare, --mirror not only maps local branches of the source to local branches of the target, it maps all refs (including remote-tracking branches, notes etc.) and sets up a refspec configuration such that all these refs are overwritten by a git remote update in the target repository. https://git-scm.com/docs/git-clone
