Quick Guide to Getting Started with Glance
|
||||
==========================================
|
||||
|
||||
Glance is a server that provides the following services:
|
||||
|
||||
* Ability to store and retrieve virtual machine images
|
||||
* Ability to store and retrieve metadata about these virtual machine image
|
||||
* FUTURE: Convert a virtual machine image from one format to another
|
||||
* FUTURE: Help caching proxies such as Varnish or Squid cache machine images
|
||||
|
||||
Communication with Glance occurs via a REST-like HTTP interface.
|
||||
|
||||
However, Glance includes a Client class that makes working with Glance
|
||||
easy and straightforward.
|
||||
|
||||
In the Cactus release, there will be also command-line tools for
|
||||
interacting with Glance.
|
||||
|
||||
Overview of Glance Architecture
|
||||
-------------------------------
|
||||
|
||||
There are two main parts to Glance's architecture:
|
||||
|
||||
* Glance API server
|
||||
* Glance Registry server(s)
|
||||
|
||||
Glance API Server
|
||||
*****************
|
||||
|
||||
The API server is the main interface for Glance. It routes requests from
|
||||
clients to registries of image metadata and to its **backend stores**, which
|
||||
are the mechanisms by which Glance actually saves incoming virtual machine
|
||||
images.
|
||||
|
||||
The backend stores that Glance can work with are as follows:
|
||||
|
||||
* **Swift**
|
||||
|
||||
Swift is the highly-available object storage project in OpenStack. More
|
||||
information can be found about Swift `here <http://swift.openstack.org>`_.
|
||||
|
||||
* **Filesystem**
|
||||
|
||||
The default backend that Glance uses to store virtual machine images
|
||||
is the filesystem backend. This simple backend writes image files to the
|
||||
local filesystem.
|
||||
|
||||
* **S3**
|
||||
|
||||
This backend allows Glance to store virtual machine images in Amazon's
|
||||
S3 service.
|
||||
|
||||
* **HTTP**
|
||||
|
||||
Glance can read virtual machine images that are available via
|
||||
HTTP somewhere on the Internet. This store is **readonly**
|
||||
|
||||
Glance Registry Servers
|
||||
***********************
|
||||
|
||||
Glance registry servers are servers that conform to the Glance Registry API.
|
||||
Glance ships with a reference implementation of a registry server that
|
||||
complies with this API (``bin/glance-registry``).
|
||||
|
||||
|
||||
Starting Up Glance's Servers
|
||||
----------------------------
|
||||
|
||||
To get started using Glance, you must first start the Glance API server.
|
||||
After installing Glance, starting up the Glance API server is easy. Simply
|
||||
start the ``glance-api`` program, like so::
|
||||
|
||||
$> glance-api
|
||||
|
||||
Configuring the Glance API server
|
||||
*********************************
|
||||
|
||||
There are a few options that can be supplied to the API server when
|
||||
starting it up:
|
||||
|
||||
* ``verbose``
|
||||
|
||||
Show more verbose/debugging output
|
||||
|
||||
* ``api_host``
|
||||
|
||||
Address of the host the registry runs on. Defaults to 0.0.0.0.
|
||||
|
||||
* ``api_port``
|
||||
|
||||
Port the registry server listens on. Defaults to 9292.
|
||||
|
||||
* ``default_store``
|
||||
|
||||
The store that the Glance API server will use by default to store
|
||||
images that are added to it. The default value is `filesystem`, and
|
||||
possible choices are: `filesystem`, `swift`, and `s3`.
|
||||
|
||||
* ``filesystem_store_datadir``
|
||||
|
||||
Directory where the filesystem store can write images to. This directory
|
||||
must be writeable by the user that runs ``glance-api``
|
||||
|
||||
.. todo::
|
||||
|
||||
Link to docs on the different stores when the documentation on Glance
|
||||
stores is complete.
