Description

Ceph is a distributed storage and network file system designed to provide excellent performance, reliability, and scalability. . This charm provides the RADOS HTTP gateway supporting S3 and Swift protocols for object storage.


Overview

Ceph is a distributed storage and network file system designed to provide excellent performance, reliability, and scalability.

This charm deploys the RADOS Gateway, a S3 and Swift compatible HTTP gateway for online object storage on-top of a ceph cluster.

This charm only supports the S3 gateway at this point in time.

Usage

In order to use this charm, it assumed that you have already deployed a ceph storage cluster using the 'ceph' charm with something like this::

juju deploy -n 3 --config ceph.yaml ceph

To deploy the RADOS gateway simple do::

juju deploy ceph-radosgw juju add-relation ceph-radosgw ceph

You can then directly access the RADOS gateway by exposing the service::

juju expose ceph-radosgw

The gateway can be accessed over port 80 (as show in juju status exposed ports).

Note that you will need to login to one of the service units supporting the ceph charm to generate some access credentials::

juju ssh ceph/0 \ 'sudo radosgw-admin user create --uid="ubuntu" --display-name="Ubuntu Ceph"'

For security reasons the ceph-radosgw charm is not setup with appropriate permissions to administer the ceph cluster.

Scale-out

Its possible to scale-out the RADOS Gateway itself::

juju add-unit -n 2 ceph-radosgw

and then stick a HA loadbalancer on the front::

juju deploy haproxy juju add-relation haproxy ceph-radosgw

Should give you a bit more bang on the front end if you really need it.

Bootnotes

The Ceph RADOS Gateway makes use of a multiverse package, libapache2-mod-fastcgi. As such it will try to automatically enable the multiverse pocket in /etc/apt/sources.list. Note that there is noting 'wrong' with multiverse components - they typically have less liberal licensing policies or suchlike.


Configuration
