- reorganized cephadm into a top-level item with a series of sub-items. - condensed the 'install' page so that it doesn't create a zillion items in the toctree on the left - started updating the cephadm/install sequence (incomplete) Signed-off-by: Sage Weil <sage@redhat.com>

Installing Ceph
|
|
===============
|
|
|
|
There are several different ways to install Ceph. Please choose the
|
|
method that best suites your needs.
|
|
|
|
Recommended methods
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
:ref:`Cephadm <cephadm>` installs and manages a Ceph cluster using containers and
|
|
systemd, with tight integration with the CLI and dashboard GUI.
|
|
|
|
* cephadm supports only Octopus and newer releases.
|
|
* cephadm is fully integrated with the new orchestration API and
|
|
fully supports the new CLI and dashboard features to manage
|
|
cluster deployment.
|
|
* cephadm requires container support (podman or docker) and
|
|
Python 3.
|
|
|
|
`Rook <https://rook.io/>`_ deploys and manages Ceph clusters running
|
|
in Kubernetes, while also enabling management of storage resources and
|
|
provisioning via Kubernetes APIs. Rook is the recommended way to run Ceph in
|
|
Kubernetes or to connect an existing Ceph storage cluster to Kubernetes.
|
|
|
|
* Rook supports only Nautilus and newer releases of Ceph.
|
|
* Rook is the preferred method for running Ceph on Kubernetes, or for
|
|
connecting a Kubernetes cluster to an existing (external) Ceph
|
|
cluster.
|
|
* Rook fully suports the new orchestrator API. New management features
|
|
in the CLI and dashboard are fully supported.
|
|
|
|
Other methods
|
|
~~~~~~~~~~~~~
|
|
|
|
`ceph-ansible <https://docs.ceph.com/ceph-ansible/>`_ deploys and manages
|
|
Ceph clusters using Ansible.
|
|
|
|
* ceph-ansible is widely deployed.
|
|
* ceph-ansible is not integrated with the new orchestrator APIs,
|
|
introduced in Nautlius and Octopus, which means that newer
|
|
management features and dashboard integration are not available.
|
|
|
|
|
|
:ref:`ceph-deploy <ceph-deploy-index>` is a tool for quickly deploying simple clusters.
|
|
|
|
.. IMPORTANT::
|
|
|
|
ceph-deploy is no longer actively maintained. It is not tested on versions of Ceph newer than Nautilus. It does not support RHEL8, CentOS 8, or newer operating systems.
|
|
|
|
`DeepSea <https://github.com/SUSE/DeepSea>`_ installs Ceph using Salt.
|
|
|
|
`jaas.ai/ceph-mon <https://jaas.ai/ceph-mon>`_ installs Ceph using Juju.
|
|
|
|
`github.com/openstack/puppet-ceph <https://github.com/openstack/puppet-ceph>`_ installs Ceph via Puppet.
|
|
|
|
Ceph can also be :ref:`installed manually <install-manual>`.
