Overview

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability.

The ceph-proxy charm deploys a proxy that acts as a ceph-mon application for an external Ceph cluster. It joins a non-charmed Ceph cluster to a Juju model.

The charm works with traditional Ceph charm clients (e.g. cinder, glance, nova-compute) but it also supports the ceph-radosgw and ceph-fs charms.

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. See the Juju documentation for details on configuring applications.

fsid

The fsid option supplies the UUID of the external cluster.

admin-key

The admin-key option supplies the admin Cephx key of the external cluster.

monitor-hosts

The monitor-hosts option supplies the network addresses (and ports) of the Monitors of the external cluster.

Deployment

Let file ceph-proxy.yaml contain the deployment configuration:

    ceph-proxy:
        fsid: a4f1fb08-c83d-11ea-8f4a-635b3b062931
        admin-key: AQCJvBFfWX+GLhAAln5dFd1rZekcGLyMmy58bQ==
        monitor-hosts: '10.246.114.21:6789 10.246.114.22:6789 10.246.114.7:6789'

To deploy:

juju deploy --config ceph-proxy.yaml ceph-proxy

Now add relations as you normally would between a ceph-mon application and another application, except substitute ceph-proxy for ceph-mon. For instance, to use the external Ceph cluster as the backend for an existing glance application:

juju add-relation ceph-proxy:client glance:ceph

Actions

Many of the ceph-mon charm's actions are supported. See file actions.yaml for the full list of actions, along with their descriptions.
