Ceph is a distributed storage and network file system designed to provide
5
excellent performance, reliability, and scalability.
7
This charm deploys the RADOS Gateway, a S3 and Swift compatible HTTP gateway
8
for online object storage on-top of a ceph cluster.
10
This charm only supports the S3 gateway at this point in time.
15
In order to use this charm, it assumed that you have already deployed a ceph
16
storage cluster using the 'ceph' charm with something like this::
18
juju deploy -n 3 --config ceph.yaml ceph
20
To deploy the RADOS gateway simple do::
22
juju deploy ceph-radosgw
23
juju add-relation ceph-radosgw ceph
25
You can then directly access the RADOS gateway by exposing the service::
27
juju expose ceph-radosgw
29
The gateway can be accessed over port 80 (as show in juju status exposed
32
Note that you will need to login to one of the service units supporting the
33
ceph-radosgw charm to generate some access credentials::
35
radosgw-admin user create --uid="ubuntu" --display-name="Ubuntu Ceph"
40
Its possible to scale-out the RADOS Gateway itself::
42
juju add-unit -n 2 ceph-radosgw
44
and then stick a HA loadbalancer on the front::
47
juju add-relation haproxy ceph-radosgw
49
Should give you a bit more bang on the front end if you really need it.
54
The Ceph RADOS Gateway makes use of a multiverse package,
55
libapache2-mod-fastcgi. As such it will try to automatically enable the
56
multiverse pocket in /etc/apt/sources.list. Note that there is noting
57
'wrong' with multiverse components - they typically have less liberal
58
licensing policies or suchlike.
