Create a new bucket owned by a project.

@bucket_name: a string representing the name of the bucket to create @context: a nova.auth.api.ApiContext object representing who owns the bucket.

metadata
dictionary of metadata around bucket, keys are ‘Name’ and ‘CreationDate’
owner_id

The handler Module

The image Module

Take uploaded bucket contents and register them as disk images (AMIs). Requires decryption using keys in the manifest.

class nova.objectstore.image.Image(image_id)

Bases: object

static add(src, description, kernel=None, ramdisk=None, public=True)

adds an image to imagestore

@type src: str @param src: location of the partition image on disk

@type description: str @param description: string describing the image contents

@type kernel: bool or str @param kernel: either TRUE meaning this partition is a kernel image or

a string of the image id for the kernel

@type ramdisk: bool or str @param ramdisk: either TRUE meaning this partition is a ramdisk image or

a string of the image id for the ramdisk

@type public: bool @param public: determine if this is a public image or private

@rtype: str @return: a string with the image id

static all()
static decrypt_image(encrypted_filename, encrypted_key, encrypted_iv, cloud_private_key, decrypted_filename)
delete()
image_path
is_authorized(context, readonly=False)
metadata
owner_id
static register_aws_image(image_id, image_location, context)
set_public(state)
static untarzip_image(path, filename)
update_user_editable_fields(args)
args is from the request parameters, so requires extra cleaning
