Installing Ceph

There are several different ways to install Ceph. Choose the method that best suits your needs.

Recommended methods

Cephadm installs and manages a Ceph cluster using containers and systemd, with tight integration with the CLI and dashboard GUI.

cephadm only supports 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 deploys and manages Ceph clusters running in Kubernetes, while also enabling management of storage resources and provisioning via Kubernetes APIs. We recommend Rook as the way to run Ceph in Kubernetes or to connect an existing Ceph storage cluster to Kubernetes.

Rook only supports 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 supports the new orchestrator API. New management features in the CLI and dashboard are fully supported.

Other methods

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.

ceph-deploy is a tool for quickly deploying clusters.

重要

ceph-deploy is no longer actively maintained.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.

ceph-salt installs Ceph using Salt and cephadm.

jaas.ai/ceph-mon installs Ceph using Juju.

github.com/openstack/puppet-ceph installs Ceph via Puppet.

Ceph can also be installed manually.
