README.md

Overview

The cinder charm is the Openstack block storage (i.e: Volume) service, whereas the cinder-nfs charm works as a subordinate of cinder, implementing a NFS backend.

Usage

Configuration

This section covers common and/or important configuration options. See file config.yaml for the full list of options, along with their descriptions and default values.

nfs-shares

A list of nfs shares that NFS driver should attempt to provision new Cinder volumes into

Multiple nfs shares can be provided, each on its own line, in a format of <host>:<share path>

  192.168.1.200:/storage
  192.168.1.201:/storage

The content will be written to /etc/cinder/nfs_shares by default or the file specified in nfs-shares-config option

nfs-shares-config

The file that contain a list of NFS shares. Cinder-volume will read this file to get its NFS backend detail

nfs-mount-options

Specify mount options. See section of the NFS man page for details.

Deployment

This charm's primary use is as a backend for the cinder charm. To do so, add a relation betweeen both charms:

  juju add-relation cinder-nfs:storage-backend cinder:storage-backend

Developing

Create and activate a virtualenv with the development requirements:

  virtualenv -p python3 venv
  source venv/bin/activate
  pip3 install -r requirements.txt
  pip3 install -r test-requirements.txt
