.. -*- rst -*- .. _image-data: Image data ********** Uploads and downloads raw image data. *These operations may be restricted to administrators. Consult your cloud operator's documentation for details.* Upload binary image data ~~~~~~~~~~~~~~~~~~~~~~~~ .. rest_method:: PUT /v2/images/{image_id}/file Uploads binary image data. *(Since Image API v2.0)* Set the ``Content-Type`` request header to ``application/octet-stream``. A multiple store backend support is introduced in the Rocky release as a part of the EXPERIMENTAL Image API v2.8. Beginning with API version 2.8, an optional ``X-Image-Meta-Store`` header may be added to the request. When present, the image data will be placed into the backing store whose identifier is the value of this header. If the store identifier specified is not recognized, a 400 (Bad Request) response is returned. When the header is not present, the image data is placed into the default backing store. * Store identifiers are site-specific. Use the :ref:`Store Discovery ` call to determine what stores are available in a particular cloud. * The default store may be determined from the :ref:`Store Discovery ` response. * A default store is always defined, so if you do not have a need to use a particular store, simply omit this header and the default store will be used. * For API versions before version 2.8, this header is silently ignored. Example call: :: curl -i -X PUT -H "X-Auth-Token: $token" \ -H "X-Image-Meta-Store: {store_identifier}" \ -H "Content-Type: application/octet-stream" \ -d @/home/glance/ubuntu-12.10.qcow2 \ $image_url/v2/images/{image_id}/file **Preconditions** Before you can store binary image data, you must meet the following preconditions: - The image must exist. - You must set the disk and container formats in the image. - The image status must be ``queued``. - Your image storage quota must be sufficient. - The size of the data that you want to store must not exceed the size that the OpenStack Image service allows. **Synchronous Postconditions** - With correct permissions, you can see the image status as ``active`` through API calls. - With correct access, you can see the stored data in the storage system that the OpenStack Image Service manages. **Troubleshooting** - If you cannot store the data, either your request lacks required information or you exceeded your allotted quota. Ensure that you meet the preconditions and run the request again. If the request fails again, review your API request. - The storage back ends for storing the data must have enough free storage space to accommodate the size of the data. Normal response codes: 204 Error response codes: 400, 401, 403, 404, 409, 410, 413, 415, 503 Request ------- .. rest_parameters:: images-parameters.yaml - Content-type: Content-Type-data - X-Image-Meta-Store: store-header - image_id: image_id-in-path Download binary image data ~~~~~~~~~~~~~~~~~~~~~~~~~~ .. rest_method:: GET /v2/images/{image_id}/file Downloads binary image data. *(Since Image API v2.0)* Example call: ``curl -i -X GET -H "X-Auth-Token: $token" $image_url/v2/images/{image_id}/file`` The response body contains the raw binary data that represents the actual virtual disk. The ``Content-Type`` header contains the ``application/octet-stream`` value. The ``Content-MD5`` header contains an MD5 checksum of the image data. Use this checksum to verify the integrity of the image data. **Preconditions** - The image must exist. **Synchronous Postconditions** - You can download the binary image data in your machine if the image has image data. - If image data exists, the call returns the HTTP ``200`` response code for a full image download request. - If image data exists, the call returns the HTTP ``206`` response code for a partial download request. - If no image data exists, the call returns the HTTP ``204`` (No Content) response code. - If no image record exists, the call returns the HTTP ``404`` response code for an attempted full image download request. - For an unsatisfiable partial download request, the call returns the HTTP ``416`` response code.
