| # Plugin SyncGit by CĂ©ondo Ltd␊ | 
| ␊ | 
| The SyncGit plugin allow the direct creation and synchronisation of␊ | 
| git repositories with the InDefero database. This requires giving␊ | 
| access to the repositories using a dedicated SSH account, usually the␊ | 
| `git` account.␊ | 
| ␊ | 
| ## Prerequisites␊ | 
| ␊ | 
| A good understanding of:␊ | 
| ␊ | 
| * the security issues related to using a SSH account on a server;␊ | 
| * the principle of public/private SSH keys;␊ | 
| * the rights/ownership of files on a Linux/BSD/nix system;␊ | 
| ␊ | 
| Yes, what you are going to do has security implications.␊ | 
| ␊ | 
| ## Git user configuration␊ | 
| ␊ | 
| On your system, you will need to create a new `git` account. This␊ | 
| account will only be used to access the git repositories and at the␊ | 
| moment cannot be shared for other use.␊ | 
| ␊ | 
| First create a new git account:␊ | 
| ␊ | 
| $ sudo adduser \␊ | 
| --system \␊ | 
| --shell /bin/sh \␊ | 
| --gecos 'git version control' \␊ | 
| --group \␊ | 
| --disabled-password \␊ | 
| --home /home/git \␊ | 
| git␊ | 
| ␊ | 
| Then, we need to create the base SSH files with the right permissions:␊ | 
| ␊ | 
| $ sudo su git␊ | 
| $ mkdir /home/git/.ssh␊ | 
| $ touch /home/git/.ssh/authorized_keys␊ | 
| $ chmod 0700 /home/git/.ssh␊ | 
| $ chmod 0600 /home/git/.ssh/authorized_keys␊ | 
| $ exit␊ | 
| ␊ | 
| ## Creation of the repositories base␊ | 
| ␊ | 
| For each project using git in InDefero a corresponding bare repository␊ | 
| will be created in `/home/git/repositories`. For example, if the␊ | 
| shortname of your project is `wonder`, it will be created in␊ | 
| `/home/git/repositories/wonder.git`␊ | 
| ␊ | 
| $ sudo -H -u git mkdir /home/git/repositories␊ | 
| ␊ | 
| ## InDefero Configuration␊ | 
| ␊ | 
| First, you need to have python installed on your system to be able to␊ | 
| run the very small python script `gitserve.py` in the `scripts`␊ | 
| folder. Here is a configuration example:␊ | 
| ␊ | 
| ␊ | 
| $cfg['git_repositories'] = '/home/git/repositories/%s.git';␊ | 
| $cfg['git_remote_url'] = 'git://yourdomain.com/%s.git';␊ | 
| $cfg['idf_plugin_syncgit_path_gitserve'] = '/home/www/indefero/scripts/gitserve.py'; # yes .py␊ | 
| $cfg['idf_plugin_syncgit_path_authorized_keys'] = '/home/git/.ssh/authorized_keys';␊ | 
| $cfg['idf_plugin_syncgit_sync_file'] = '/tmp/SYNC-GIT';␊ | 
| ␊ | 
| When someone will change his SSH key or add a new one, the␊ | 
| `/tmp/SYNC-GIT` file will be created. The cron job␊ | 
| `/home/www/indefero/scripts/gitcron.php` will see the file and update␊ | 
| the content of the `authorized_keys` file.␊ | 
| ␊ | 
| ## Cron Job Configuration␊ | 
| ␊ | 
| You need to run a cron job every now and then to synchronize the SSH␊ | 
| keys. The command to run in the cron job is:␊ | 
| ␊ | 
| php /home/www/indefero/scripts/gitcron.php␊ | 
| ␊ | 
| The user of the cron job must be `git`. |
