=========================================
 Cloning the Ceph Source Code Repository
=========================================

To clone a Ceph branch of the Ceph source code, go to `github Ceph
Repository`_, select a branch (``main`` by default), and click the **Download
ZIP** button.

.. _github Ceph Repository: https://github.com/ceph/ceph

To clone the entire git repository, :ref:`install <install-git>` and configure
``git``.

.. _install-git:

Install Git
===========

To install ``git`` on Debian/Ubuntu, run the following command:

.. prompt:: bash $

   sudo apt-get install git


To install ``git`` on CentOS/RHEL, run the following command:

.. prompt:: bash $

   sudo yum install git


You must have a ``github`` account. If you do not have a ``github``
account, go to `github.com`_ and register.  Follow the directions for setting
up git at `Set Up Git`_.

.. _github.com: https://github.com
.. _Set Up Git: https://help.github.com/linux-set-up-git


Add SSH Keys (Optional)
=======================

To commit code to Ceph or to clone the respository by using SSH
(``git@github.com:ceph/ceph.git``), you must generate SSH keys for github. 

.. tip:: If you want only to clone the repository, you can 
   use ``git clone --recursive https://github.com/ceph/ceph.git`` 
   without generating SSH keys.

To generate SSH keys for ``github``, run the following command:

.. prompt:: bash $

   ssh-keygen

To print the SSH key that you just generated and that you will add to your
``github`` account, use the ``cat`` command. (The following example assumes you
used the default file path.):

.. prompt:: bash $

   cat .ssh/id_rsa.pub

Copy the public key.

Go to your ``github`` account, click "Account Settings" (represented by the
'tools' icon), and click "SSH Keys" on the left side navbar.

Click "Add SSH key" in the "SSH Keys" list, enter a name for the key, paste the
key you generated, and press the "Add key" button.


Clone the Source
================

To clone the Ceph source code repository, run the following command:

.. prompt:: bash $

   git clone --recursive https://github.com/ceph/ceph.git

After ``git clone`` has run, you should have a full copy of the Ceph 
repository.

.. tip:: Make sure you maintain the latest copies of the submodules included in
   the repository. Running ``git status`` will tell you whether the submodules
   are out of date. See :ref:`update-submodules` for more information.


.. prompt:: bash $

   cd ceph
   git status

.. _update-submodules:

Updating Submodules
-------------------

If your submodules are out of date, run the following commands:

   .. prompt:: bash $

      git submodule update --force --init --recursive --progress
      git clean -fdx
      git submodule foreach git clean -fdx

If you still have problems with a submodule directory, use ``rm -rf [directory
name]`` to remove the directory. Then run ``git submodule update --init
--recursive --progress`` again.


Choose a Branch
===============

Once you clone the source code and submodules, your Ceph repository 
will be on the ``main`` branch by default, which is the unstable 
development branch. You may choose other branches too.

- ``main``: The unstable development branch.
- ``stable-release-name``: The name of the stable, :ref:`active-releases`. e.g. ``Pacific``
- ``next``: The release candidate branch.

	git checkout main
