========================================================== ``gitosis`` -- software for hosting ``git`` repositories ========================================================== Manage ``git`` repositories, provide access to them over SSH, with tight access control and not needing shell accounts. .. note:: Documentation is still lacking, and non-default configurations (e.g. config file, repositories, installing in a location that is not in ``PATH``) basically have not been tested at all. Basic usage should be very reliable -- the project has been hosting itself for a long time. Any help is welcome. ``gitosis`` aims to make hosting ``git`` repos easier and safer. It manages multiple repositories under one user account, using SSH keys to identify users. End users do not need shell accounts on the server, they will talk to one shared account that will not let them run arbitrary commands. ``gitosis`` is licensed under the GPL, see the file ``COPYING`` for more information. You can get ``gitosis`` via ``git`` by saying:: git clone git://eagain.net/gitosis And install it via:: python setup.py install Though you may want to use e.g. ``--prefix=``. For Debian/Ubuntu users, the source is debianized. Setting up ========== First, we will create the user that will own the repositories. This is usually called ``git``, but any name will work, and you can have more than one per system if you really want to. The user does not need a password, but does need a valid shell (otherwise, SSH will refuse to work). I usually store ``git`` repositories in the subtree ``/srv/example.com/git`` (replace ``example.com`` with your own domain). You may choose another location. Adjust to suit and run:: sudo adduser \ --system \ --shell /bin/sh \ --gecos 'git version control' \ --group \ --disabled-password \ --home /srv/example.com/git \ git This command is known to work in Debian and Ubuntu. Your mileage may vary. You will need an SSH public key to continue. If you don't have one, you need to generate one. See the man page for ``ssh-keygen``, and you may also be interested in ``ssh-agent``. Create it on your personal computer, and protect the *private* key well -- that includes not transferring it over the network. Next, we need to set things up for this newly-created user. The following command will create a ``~/repositories`` that will hold the ``git`` repositories, a ``~/.gitosis.conf`` that will be a symlink to the actual configuration file, and it will add the SSH public key to ``~/.ssh/authorized_keys`` with a ``command=`` option that restricts it to running ``gitosis-serve``. Run:: sudo -H -u git gitosis-init <FILENAME.pub # (or just copy-paste the public key when prompted) then just ``git clone git@SERVER:gitosis-admin.git``, and you get a repository with SSH keys as ``keys/USER.pub`` and a ``gitosis.conf`` where you can configure who has access to what. .. warning:: For now, ``gitosis`` uses the ``HOME`` environment variable to locate where to write its files. If you use ``sudo -u`` without ``-H``, ``sudo`` will leave the old value of ``HOME`` in place, and this will cause trouble. There will be a workaround for that later on, but for now, always remember to use ``-H`` if you're sudoing to the account. You should always edit the configuration file via ``git``. The file symlinked to ``~/.gitosis.conf`` on the server will be overwritten when pushing changes to the ``gitosis-admin.git`` repository. Edit the settings as you wish, commit and push. That's pretty much it! Once you push, ``gitosis`` will immediately make your changes take effect on the server. Managing it =========== To add new users: - add a ``keys/USER.pub`` file - authorize them to read/write repositories as needed (or just authorize the group ``@all``) To create new repositories, just authorize writing to them and push. It's that simple! For example: let's assume your username is ``jdoe`` and you want to create a repository ``myproject``. In your clone of ``gitosis-admin``, edit ``gitosis.conf`` and add:: [group myteam] members = jdoe writable = myproject Commit that change and push. Then create the initial commit and push it:: mkdir myproject cd mypyroject git init git remote add myserver git@MYSERVER:myproject.git # do some work, git add and commit files git push myserver master:refs/heads/master That's it. If you now add others to ``members``, they can use that repository too. Example configuration ===================== .. include:: example.conf :literal: Contact ======= You can email the author at ``tv@eagain.net``, or hop on ``irc.freenode.net`` channel ``#git`` and hope for the best. There will be more, keep an eye on http://eagain.net/ and/or the git mailing list.
