Cyclades/Image API Guide |

======================== |

|

Introduction |
| 7 |
------------ |
| 8 |
|
| 9 |
The Image Service of `Synnefo <http://www.synnefo.org>`_ is implemented as part |
| 10 |
of Cyclades. It exposes the OpenStack `Glance API |
| 11 |
<http://docs.openstack.org/developer/glance/glanceapi.html>`_, with minor |
| 12 |
changes or additions wherever needed. |
| 13 |
|
| 14 |
This document's goals are: |
| 15 |
|
| 16 |
* Define the Cyclades/Image ReST API |
| 17 |
* Clarify the differences between Cyclades/Image and Glance |
| 18 |

Authentication |
| 39 |
-------------- |
| 40 |
|
| 41 |
**Image** depends on Astakos to handle authentication of clients. An |
| 42 |
authentication token must be obtained from the identity manager which should be |
| 43 |
send along with each API requests through the *X-Auth-Token* header. Image |
| 44 |
handles the communication with Astakos to verify the token validity and obtain |
| 45 |
identity credentials. |
| 46 |
|
| 47 |
**Glance** handles authentication in a `similar manner |
| 48 |
<http://docs.openstack.org/developer/glance/glanceapi.html#authentication>`_, |
| 49 |
with the only difference being the suggested identity manager. |

Add or update an image |
| 231 |
---------------------- |
| 232 |
|
| 233 |
According to the Synnefo approach, this request performs two operations: |
| 234 |
|
| 235 |
* registers a new image to Cyclades/Image |
| 236 |
* commits metadata for the new image |
| 237 |
* update the metadata of an existing image |
| 238 |
|
| 239 |
The physical image file must be uploaded on a `Pithos <pithos.html>`_ server, |
| 240 |
at a space accessible by the user. The Pithos location of the physical file |
| 241 |
acts as a key for the image (image ids and image locations are uniquely |
| 242 |
coupled). |
| 243 |
|
| 244 |
According to the OpenStack approach, this request performs the first two |
| 245 |
functionalities by uploading the the image data and metadata to Glance. In |
| 246 |
Glance, the update mechanism is not implemented with this specific request. |

Update an Image |
| 336 |
--------------- |
| 337 |
|
| 338 |
In Cyclades/Image, an image can be updated either by re-registering with |
| 339 |
different metadata, or by using the request described in the present |
| 340 |
subsection. |
| 341 |
|
| 342 |
In Glance, an update is implemented as a *PUT* request on ``/images`` URI. The |
| 343 |
method described bellow is not part of the Glance API. |

Retrieve Image Metadata |
| 429 |
----------------------- |
| 430 |
|
| 431 |
This request returns the metadata of an image. Images are identified by their |
| 432 |
unique image id. |
| 433 |
|
| 434 |
In a typical scenario, client applications would query the server to `List |
| 435 |
Available Images <#id2>`_ for them and then choose one of the image ids |
| 436 |
returned. |

Retrieve Raw Image Data |
| 540 |
----------------------- |
| 541 |
|
| 542 |
In **Image**, the raw image data is stored at a `Pithos <pithos.html>`_ |
| 543 |
server and it can be downloaded from the Pithos web UI, with a `client |
| 544 |
<https://okeanos.grnet.gr/services/pithos/>`_ or with `kamaki |
| 545 |
<http://www.synnefo.org/docs/kamaki/latest/index.html>`_. The location of an |
| 546 |
image file can be retrieved from the *X-Image-Meta-Location* header field (see |
| 547 |
`Retrieve Image Meta <#id10>`_) |
| 548 |
|
| 549 |
In **Glance**, the raw image can be downloaded with a GET request on |
| 550 |
``/images/<image-id>``. |
