Answer 1

Have look at http://planzero.org/blog/2012/10/24/hosting_an_admin-friendly_git_server_with_git-shell

You can create a git-shell-commands directory in your git user's home directory, then copy in the sample tools from the page to allow creating repo via guest-shell.

Answer 2

Will I have each time to connect with a sudoer and create the repo then chown it ?

Yes, you can see an example in the article "Git Local Repository Setup Guide" by Rami Al-Ghanmi (alghanmi):

Repository Setup & Essentials

First, we create the git user and set the account up for SSH Public Key Authentication and no terminal login.
That means, the git account can not login using a password (only via PKA) and has no regular shell access. Instead, it will be using a special git shell with a limited set of commands.

#Create git user account
sudo adduser --shell $(which git-shell) --gecos 'git version control' --disabled-password git

#Add git user to the appropriate groups
sudo usermod -a -G www-data git
sudo usermod -a -G developers git

#Setup authorized_keys file for access
sudo mkdir -p /home/git/.ssh
sudo touch /home/git/.ssh/authorized_keys
sudo chmod 600 /home/git/.ssh/authorized_keys
sudo chmod 700 /home/git/.ssh

#Copy the git-shell-commands to get limited shell access
sudo cp -r /usr/share/doc/git/contrib/git-shell-commands /home/git/
sudo chmod 750 /home/git/git-shell-commands/*

#Fix permissions
sudo chown -R git:git /home/git/

Add your SSH generated key to the authorized key list. You can repeat this step for all users you wish to give access to

cat ~/.ssh/id_rsa.pub | sudo tee -a /home/git/.ssh/authorized_keys

Allow the git user to access the system via SSH

echo "AllowUsers git" | sudo tee -a /etc/ssh/sshd_config
sudo service ssh restart

Create a location to store repositories

sudo mkdir -p /home/repo
sudo chown -R git:www-data /home/repo

Create a HelloWorld Repository

#Create the directory (always end with .git)
sudo mkdir /home/repo/helloworld.git
cd /home/repo/helloworld.git
#Initialize a bare repository
sudo git --bare init

#Some meta-data
echo "Hello World Repository. Testing system configuration" | sudo tee /home/repo/helloworld.git/description
echo "[gitweb]" | sudo tee -a /home/repo/helloworld.git/config
echo -e "\towner = \\"Rami Al-Ghanmi\\"" | sudo tee -a /home/repo/helloworld.git/config

#Fix ownership of repository
sudo chown -R git:www-data /home/repo/helloworld.git

Clone the repository, though empty, and add some code.
Ignore the warning about cloning an empty repository.

git clone git@$(hostname):/home/repo/helloworld.git
cd helloworld
wget https://raw.github.com/gist/3205222/HelloWorld.cpp
git add HelloWorld.cpp
git commit -m "Initial commit with HelloWorld in C++"
git push origin master

You can use a git-shell-commands directory to extend git-shell with custom commands, these can then be remotely executed using ssh.

For example create ~git/git-shell-commands/newgit with this content:

#!/bin/sh
mkdir -p ~/$1
cd ~/$1
git init --bare

Then chmod +x ~git/git-shell-commands/newgit to allow execution.

To use it, run:

ssh git@server newgit newrepo.git

this is enough to create a new bare git repository, it can be cloned using:

git clone git@server:newrepo.git
