Overview
|
||||
--------
|
||||
|
||||
This charm provides the Cinder volume service for OpenStack. It is intended to
|
||||
be used alongside the other OpenStack components, starting with the Folsom
|
||||
release.
|
||||
|
||||
Cinder is made up of 3 separate services: an API service, a scheduler and a
|
||||
volume service. This charm allows them to be deployed in different
|
||||
combination, depending on user preference and requirements.
|
||||
|
||||
This charm was developed to support deploying Folsom on both
|
||||
Ubuntu Quantal and Ubuntu Precise. Since Cinder is only available for
|
||||
Ubuntu 12.04 via the Ubuntu Cloud Archive, deploying this charm to a
|
||||
Precise machine will by default install Cinder and its dependencies from
|
||||
the Cloud Archive.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Cinder may be deployed in a number of ways. This charm focuses on 3 main
|
||||
configurations. All require the existence of the other core OpenStack
|
||||
services deployed via Juju charms, specifically: mysql, rabbitmq-server,
|
||||
keystone and nova-cloud-controller. The following assumes these services
|
||||
have already been deployed.
|
||||
|
||||
a. Basic, all-in-one using local storage and iSCSI.
|
||||
|
||||
The api server, scheduler and volume service are all deployed into the same
|
||||
unit. Local storage will be initialized as a LVM phsyical device, and a volume
|
||||
group initialized. Instance volumes will be created locally as logical volumes
|
||||
and exported to instances via iSCSI. This is ideal for small-scale deployments
|
||||
or testing:
|
||||
|
||||
$ cat >cinder.cfg <<END
|
||||
cinder:
|
||||
block-device: sdc
|
||||
overwrite: true
|
||||
END
|
||||
$ juju deploy --config=cinder.cfg cinder
|
||||
$ juju add-relation cinder keystone
|
||||
$ juju add-relation cinder mysql
|
||||
$ juju add-relation cinder rabbitmq-server
|
||||
$ juju add-relation cinder nova-cloud-controller
|
||||
|
||||
b. Separate volume units for scale out, using local storage and iSCSI.
|
||||
|
||||
Separating the volume service from the API service allows the storage pool
|
||||
to easily scale without the added complexity that accompanies load-balancing
|
||||
the API server. When we've exhausted local storage on volume serve, we can
|
||||
simply add-unit to expand our capacity. Future requests to allocate volumes
|
||||
will be distributed across the pool for volume servers according to the
|
||||
availability of storage space.
|
||||
|
||||
$ cat >cinder.cfg <<END
|
||||
cinder-api:
|
||||
enabled-services: api, scheduler
|
||||
cinder-volume:
|
||||
enabled-serfvices: volume
|
||||
block-device: sdc
|
||||
overwrite: true
|
||||
END
|
||||
$ juju deploy --config=cinder.cfg cinder cinder-api
|
||||
$ juju deploy --config=cinder.cfg cinder cinder-api
|
||||
$ juju add-relation cinder-api mysql
|
||||
$ juju add-relation cinder-api rabbitmq-server
|
||||
$ juju add-relation cinder-api keystone
|
||||
$ juju add-relation cinder-api nova-cloud-controller
|
||||
$ juju add-relation cinder-volume mysql
|
||||
$ juju add-relation cinder-volume rabbitmq-server
|
||||
|
||||
# When more storage is needed, simply add more volume servers.
|
||||
$ juju add-unit cinder-volume
|
||||
|
||||
c. All-in-one using Ceph-backed RBD volumes.
|
||||
|
||||
All 3 services can be deployed to the same unit, but instead of relying
|
||||
on local storage to back volumes an external Ceph cluster is used. This
|
||||
allows scalability and redundancy needs to be satisified and Cinder's RBD
|
||||
driver used to create, export and connect volumes to instances. This assumes
|
||||
a functioning Ceph cluster has already been deployed using the official Ceph
|
||||
charm and a relation exists between the Ceph service and nova-compute.
|
||||
service.

||||

|
||||
cinder:
|
||||
block-device: None

|
||||
$ juju deploy --config=cinder.cfg cinder
|

$ juju add-relation cinder ceph
|
||||
$ juju add-relation cinder keystone
|

$ juju add-relation cinder mysql

Configuration
|
||||
-------------
|
||||
|
||||
The default value for most config options should work for most deployments.
|
||||
|
||||
Users should be aware of three options, in particular:
|
||||
|
||||
openstack-origin: Allows Cinder to be installed from a specific apt repository.
|
||||
See config.yaml for a list of supported sources.
|
||||
|
||||
block-device: When using local storage, a block device should be specified to
|
||||
back a LVM volume group. It's important this device exists on
|
||||
all nodes that the service may be deployed to.
|
||||
|
||||
overwrite: Whether or not to wipe local storage that of data that may prevent
|
||||
it from being initialized as a LVM phsyical device. This includes
|
||||
filesystems and partition tables. *CAUTION*
|
||||
|
||||
enabled-services: Can be used to separate cinder services between service
|
||||
service units (see previous section)

Describe the intended usage of this charm and anything unique about how

this charm relates to others here.
|
||||
|

This README will be displayed in the Charm Store, it should be either Markdown or RST. Ideal READMEs include instructions on how to use the charm, expected usage, and charm features that your audience might be interested in.

Overview
|

--------
|
||||
|
||||
This charm provides (service) from (service homepage). Add a description here of what the service itself actually does.
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Step by step instructions on using the charm:
|
||||
|
||||
juju deploy servicename
|
||||
|
||||
and so on. If you're providing a web service or something that the end user needs to go to, tell them here, especially if you're deploying a service that might listen to a non-default port.
|
||||
|
||||
You can then browse to http://ip-address to configure the service.
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
The configuration options will be listed on the charm store, however If you're making assumptions or opinionated decisions in the charm (like setting a default administrator password), you should detail that here so the user knows how to change it immediately, etc.

Contact Information

Though this will be listed in the charm store itself don't assume a user will know that, so include that information here:
