glanceclient.v2.images module¶

class glanceclient.v2.images.Controller(http_client, schema_client)¶

Bases: object

add_location(image_id, url, metadata, validation_data=None)¶

Add a new location entry to an image’s list of locations.

It is an error to add a URL that is already present in the list of locations.

Parameters:	image_id – ID of image to which the location is to be added. url – URL of the location to add. metadata – Metadata associated with the location. validation_data – Validation data for the image.
Returns:	The updated image

create(**kwargs)¶

Create an image.

data(image_id, do_checksum=True, allow_md5_fallback=False)¶

Retrieve data of an image.

When do_checksum is enabled, validation proceeds as follows:

1. if the image has a ‘os_hash_value’ property, the algorithm specified in the image’s ‘os_hash_algo’ property will be used to validate against the ‘os_hash_value’ value. If the specified hash algorithm is not available AND allow_md5_fallback is True, then continue to step #2
2. else if the image has a checksum property, MD5 is used to validate against the ‘checksum’ value
3. else if the download response has a ‘content-md5’ header, MD5 is used to validate against the header value
4. if none of 1-3 obtain, the data is not validated (this is compatible with legacy behavior)

Parameters:	image_id – ID of the image to download do_checksum – Enable/disable checksum validation allow_md5_fallback – Use the MD5 checksum for validation if the algorithm specified by the image’s ‘os_hash_algo’ property is not available
Returns:	An iterable body or None

deactivate(image_id)¶

Deactivate an image.

delete(image_id)¶

Delete an image.

delete_locations(image_id, url_set)¶

stage(image_id, image_data, image_size=None)¶

Upload the data to image staging.

Parameters:	image_id – ID of the image to upload data for. image_data – File-like object supplying the data to upload. image_size – Unused - present for backwards compatibility

update(image_id, remove_props=None, **kwargs)¶

Update attributes of an image.

Parameters:	image_id – ID of the image to modify. remove_props – List of property names to remove kwargs – Image attribute names and their new values.

update_location(image_id, url, metadata)¶

The URL specified must be already present in the image’s list of locations.

Parameters:	image_id – ID of image whose location is to be updated. url – URL of the location to update. metadata – Metadata associated with the location.
Returns:	The updated image
