This tutorial will show you how to set up a shared git repo with multiple accounts over ssh. Only ssh, not gitolite or any other software. This is usefull if you have a small team of people that don't often need access to the repo and don't want something like github or bitbucket. With this you can use existing infrastructure.

PCBWay referral link (You get $5, I get $20 after you've placed an order)
Digital Ocea referral link ($200 credit for 60 days. Spend $25 after your credit expires and I'll get $25!)
I have used this for a sysadmin team which had a few scripts scattered.
Folders and Permissions
First set up a new group for the users of the repository. You can use the
groupadd command but I find it easier to edit /etc/group and add a line line
this:
gitusers:x:2222:user1,user2,user3,user4
Do note that all the users you add above should have an account on the system.
(adduser user/useradd user)
Now create a folder to house the repo's:
mkdir -p /var/git/repository1
Then change the group permissions on that folder:
chgrp gitusers /var/git/repository1
chmod g+ws /var/git/repository1
Repository
We can now create the repository. Navigate to the folder and initialize the repository:
cd /var/git/repository
git init --bare --shared=group
That's it. Now you can clone, pull, push and commit the repo like normal:
git clone git+ssh://user1@gitserver/var/git/repository1
Script
A simple script which makes the above easier. This assuming the group is
gitusers and the root path is /var/git/.
#!/bin/bash
GITGROUP="gitusers"
REPOPATH="/var/git"
if [[ -z "$1" ]]; then
echo "You must specify a repo name"
echo "./$0 repo_name"
exit 1
fi
mkdir "${PATH}/$1"
chgrp "${GITGROUP}" "${PATH}/$1"
chmod 2775 "${PATH}/$1"
pushd "${PATH}/$1"
git init --bare --shared=group
popd
echo "Created repo $1."
echo "Clone URL: git+ssh://$(hostname -f)${PATH}/$1"
If you need to trigger a Jenkins build after a commit you can add the following
post-receive hook.
