Subject: Add support for Ceph NFS Gateway
X-Git-Tag: v1.0.6~77^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=4c2a433acb02048b3d1dc2dcab8ebb0c94ef9add;p=ceph-ansible.git

Add support for Ceph NFS Gateway

Ceph has the ability to export it's filesystem via NFS using Ganesha.
Add a ceph-nfs role that will start Ganesha and export the Ceph
filesystems.

Note that, although support is going in to export RGW via NFS, this is
not working yet.

+# Ansible role: Ceph NFS Gateway
+
+This role bootstraps Ceph NFS Gateway(s).
+It can bootstrap dockerized Ceph NFS Gateway(s).  NFS support is provided by
+the NFS Ganesha project.
+
+It can provide one or both of NFS File access (requires at least one ceph-mds
+role) or NFS Object access (requires at least one ceph-rgw role).
+
+# Requirements
+
+Nothing, it runs out of the box.
+
+# Role variables
+
+Have a look at: `defaults/main.yml`.
+
+## Mandatory variables
+
+None.
+
+# Dependencies
+
+The role `ceph.ceph-common` must be installed.
+
+# Example Playbook
+
+```
+- hosts: servers
+  remote_user: ubuntu
+  roles:
+     - { role: ceph.ceph-nfs }
+```
