 Ceph Internals
================

.. note:: For information on how to use Ceph as a library (from your own
   software), see :doc:`/api/index`.

This section contains documentation about the internal architecture and
implementation details of Ceph components. It is organized by major subsystem
to help developers navigate the codebase.

Getting Started with Development
================================

.. note:: You may also be interested in the :doc:`/dev/developer_guide/index` documentation.

Community Mailing Lists
-----------------------

The ``dev@ceph.io`` list is for discussion about the development of Ceph,
its interoperability with other technology, and the operations of the
project itself.  Subscribe by sending a message to ``dev-join@ceph.io``
with the word `subscribe` in the subject.

Alternatively you can visit https://lists.ceph.io and register.

The ceph-devel@vger.kernel.org list is for discussion
and patch review for the Linux kernel Ceph client component.
Subscribe by sending a message to ``majordomo@vger.kernel.org`` with the line::

 subscribe ceph-devel

in the body of the message.

Starting a Development-mode Ceph Cluster
----------------------------------------

Compile the source and then run the following commands to start a
development-mode Ceph cluster::

	cd build
	OSD=3 MON=3 MGR=3 ../src/vstart.sh -n -x
	# check that it's there
	bin/ceph health
