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
