(store, *args, **kwargs)¶get_connection
(location, context=None)¶get_manager
(store_location, context=None, allow_reauth=False)¶Return appropriate connection manager for store
The method detects store type (singletenant or multitenant) and returns appropriate connection manager (singletenant or multitenant) that allows to request swiftclient connections.
Parameters: |
|
---|---|
Returns: | connection manager for store |
get_schemes
()¶get_size
(location, connection=None, context=None)¶get_store_connection
(auth_token, storage_url)¶Get initialized swift connection
Parameters: |
|
---|---|
Returns: | swiftclient connection that allows to request container and others |
init_client
(location, context=None)¶Initialize and return client to authorize against keystone
The method invariant is the following: it always returns Keystone client that can be used to receive fresh token in any time. Otherwise it raises appropriate exception. :param location: swift location data :param context: user context (it is not required if user grants are specified for single tenant store) :return correctly initialized keystone client

()¶create_location
(image_id, context=None)¶get_connection
(location, context=None)¶get_container_name
(image_id, default_image_container)¶Returns appropriate container name depending upon value of
swift_store_multiple_containers_seed
. In single-container mode,
which is a seed value of 0, simply returns default_image_container.
In multiple-container mode, returns default_image_container as the
prefix plus a suffix determined by the multiple container seed
Parameters: |

get_manager
(store_location, context=None, allow_reauth=False)¶init_client
(location, context=None)¶Initialize keystone client with swift service user credentials

Store
(conf)¶glance_store._drivers.swift.store.
StoreLocation
(store_specs, conf)¶Bases: glance_store.location.StoreLocation
Class describing a Swift URI. A Swift URI can look like any of the following:
swift://user:pass@authurl.com/container/obj-id swift://account:user:pass@authurl.com/container/obj-id swift+http://user:pass@authurl.com/container/obj-id swift+https://user:pass@authurl.com/container/obj-id
When using multi-tenant a URI might look like this (a storage URL):
swift+https://example.com/container/obj-id
The swift+http:// URIs indicate there is an HTTP authentication URL. The default for Swift is an HTTPS authentication URL, so swift:// and swift+https:// are the same…
get_uri
(credentials_included=True)¶parse_uri
(uri)¶Parse URLs. This method fixes an issue where credentials specified in the URL are interpreted differently in Python 2.6.1+ than prior versions of Python. It also deals with the peculiarity that new-style Swift URIs have where a username can contain a ‘:’, like so:
swift://account:user:pass@authurl.com/container/obj and for system created locations with account reference swift+config://account_reference/container/obj
process_specs
()¶swift_url
¶Creates a fully-qualified auth address that the Swift client library can use. The scheme for the auth_address is determined using the scheme included in the location field.
HTTPS is assumed, unless ‘swift+http’ is specified.
