keystoneclient.access module

class keystoneclient.access.AccessInfo(*args, **kwargs)

Bases: dict

Encapsulates a raw authentication token from keystone.

Provides helper methods for extracting useful values from that token.

audit_chain_id

Return the audit chain ID if present.

In the event that a token was rescoped then this ID will be the audit_id of the initial token. Returns None if no value present.

Returns:str or None.

keystoneclient.adapter module

class keystoneclient.adapter.Adapter(session, service_type=None, service_name=None, interface=None, region_name=None, endpoint_override=None, version=None, auth=None, user_agent=None, connect_retries=None, logger=None)

Bases: object

An instance of a session with local variables.

A session is a global object that is shared around amongst many clients. It therefore contains state that is relevant to everyone. There is a lot of state such as the service type and region_name that are only relevant to a particular client that is using the session. An adapter provides a wrapper of client local data around the global session object.

Parameters:
  • session (keystoneclient.session.Session) – The session object to wrap.
  • service_type (str) – The default service_type for URL discovery.
  • service_name (str) – The default service_name for URL discovery.
  • interface (str) – The default interface for URL discovery.
  • region_name (str) – The default region_name for URL discovery.
  • endpoint_override (str) – Always use this endpoint URL for requests for this client.
  • version (tuple) – The version that this API targets.
  • auth (keystoneclient.auth.base.BaseAuthPlugin) – An auth plugin to use instead of the session one.
  • user_agent (str) – The User-Agent string to set.
  • connect_retries (int) – the maximum number of retries that should be attempted for connection errors. Default None - use session default which is don’t retry.
  • logger (logging.Logger) – A logging object to use for requests that pass through this adapter.
delete(url, **kwargs)
get(url, **kwargs)
get_endpoint(auth=None, **kwargs)

Get an endpoint as provided by the auth plugin.

Parameters:auth (keystoneclient.auth.base.BaseAuthPlugin) – The auth plugin to use for token. Overrides the plugin on the session. (optional)

Current project_id or None if not supported by plugin.
Return type:

string
get_token(auth=None)

Return a token as provided by the auth plugin.

Parameters:auth (keystoneclient.auth.base.BaseAuthPlugin) – The auth plugin to use for token. Overrides the plugin on the session. (optional)
Raises:keystoneclient.exceptions.AuthorizationFailure – if a new token fetch fails.
Returns:A valid token.
Return type:string

class keystoneclient.adapter.LegacyJsonAdapter(session, service_type=None, service_name=None, interface=None, region_name=None, endpoint_override=None, version=None, auth=None, user_agent=None, connect_retries=None, logger=None)

Bases: keystoneclient.adapter.Adapter

Make something that looks like an old HTTPClient.

A common case when using an adapter is that we want an interface similar to the HTTPClients of old which returned the body as JSON as well.

You probably don’t want this if you are starting from scratch.

request(*args, **kwargs)

keystoneclient.base module

Base utilities to build API operation managers and objects on top of.

class keystoneclient.base.CrudManager(client)

Bases: keystoneclient.base.Manager

Base manager class for manipulating Keystone entities.

Children of this class are expected to define a collection_key and key.

  • collection_key: Usually a plural noun by convention (e.g. entities); used to refer collections in both URL’s (e.g. /v3/entities) and JSON objects containing a list of member resources (e.g. {‘entities’: [{}, {}, {}]}).
  • key: Usually a singular noun by convention (e.g. entity); used to refer to an individual member of the collection.
base_url = None
build_key_only_query(params_list)

Build a query that does not include values, just keys.

The Identity API has some calls that define queries without values, this can not be accomplished by using urllib.parse.urlencode(). This method builds a query using only the keys.

build_url(dict_args_in_out=None)

Build a resource URL for the given kwargs.

Given an example collection where collection_key = ‘entities’ and key = ‘entity’, the following URL’s could be generated.

By default, the URL will represent a collection of entities, e.g.:

/entities

If kwargs contains an entity_id, then the URL will represent a specific member, e.g.:

/entities/{entity_id}

If a base_url is provided, the generated URL will be appended to it.

If a ‘tail’ is provided, it will be appended to the end of the URL.

collection_key = None
create(*args, **kwargs)
delete(*args, **kwargs)
find(*args, **kwargs)

Find a single item with attributes matching **kwargs.

get(*args, **kwargs)

key = None
list(*args, **kwargs)
put(*args, **kwargs)
update(*args, **kwargs)
class keystoneclient.base.Manager(client)

Bases: object

Basic manager type providing common operations.

Managers interact with a particular type of API (servers, flavors, images, etc.) and provide CRUD operations for them.

Parameters:client – instance of BaseClient descendant for HTTP requests
api

The client.

Warning

This property is deprecated as of the 1.7.0 release in favor of client() and may be removed in the 2.0.0 release.

resource_class = None
class keystoneclient.base.ManagerWithFind(client)

Bases: keystoneclient.base.Manager

Manager with additional find()/findall() methods.

find(**kwargs)

Find a single item with attributes matching **kwargs.

This isn’t very efficient: it loads the entire list then filters on the Python side.

Find all items with attributes matching **kwargs.

This isn’t very efficient: it loads the entire list then filters on the Python side.

list()
class keystoneclient.base.Resource(manager, info, loaded=False)

Human-readable ID which can be used for bash completion.

is_loaded()
set_loaded(val)
to_dict()
keystoneclient.base.filter_kwargs(f)

keystoneclient.client module

keystoneclient.client.Client(version=None, unstable=False, session=None, **kwargs)

Factory function to create a new identity service client.

The returned client will be either a V3 or V2 client. Check the version using the version property or the instance’s class (with instanceof).

Parameters:
  • version (tuple) – The required version of the identity API. If specified the client will be selected such that the major version is equivalent and an endpoint provides at least the specified minor version. For example to specify the 3.1 API use (3, 1). (optional)
  • unstable (bool) – Accept endpoints not marked as ‘stable’. (optional)
  • session (keystoneclient.session.Session) – A session object to be used for communication. If one is not provided it will be constructed from the provided kwargs. (optional)

keystoneclient.discover module

class keystoneclient.discover.Discover(session=None, authenticated=None, **kwargs)

Bases: keystoneclient._discover.Discover

A means to discover and create clients.

Clients are created depending on the supported API versions on the server.

Querying the server is done on object creation and every subsequent method operates upon the data that was retrieved.

The connection parameters associated with this method are the same format and name as those used by a client (see keystoneclient.v2_0.client.Client and keystoneclient.v3.client.Client). If not overridden in subsequent methods they will also be what is passed to the constructed client.

In the event that auth_url and endpoint is provided then auth_url will be used in accordance with how the client operates.

Warning

Creating an instance of this class without using the session argument is deprecated as of the 1.7.0 release and may be removed in the 2.0.0 release.

Parameters:
  • session (keystoneclient.session.Session) – A session object that will be used for communication. Clients will also be constructed with this session.
  • auth_url (string) – Identity service endpoint for authorization. (optional)
  • endpoint (string) – A user-supplied endpoint URL for the identity service. (optional)
  • original_ip (string) – The original IP of the requesting user which will be sent to identity service in a ‘Forwarded’ header. (optional) This is ignored if a session is provided. Deprecated as of the 1.7.0 release and may be removed in the 2.0.0 release.

  • key (string) – Path to the Privacy Enhanced Mail (PEM) file which contains the unencrypted client private key needed to established two-way SSL connection with the identity service. (optional) This is ignored if a session is provided. Deprecated as of the 1.7.0 release and may be removed in the 2.0.0 release.
  • cert (string) – Path to the Privacy Enhanced Mail (PEM) file which contains the corresponding X.509 client certificate needed to established two-way SSL connection with the identity service. (optional) This is ignored if a session is provided. Deprecated as of the 1.7.0 release and may be removed in the 2.0.0 release.
  • insecure (boolean) – Does not perform X.509 certificate validation when establishing SSL connection with identity service. default: False (optional) This is ignored if a session is provided. Deprecated as of the 1.7.0 release and may be removed in the 2.0.0 release.
  • authenticated (bool) – Should a token be used to perform the initial discovery operations. default: None (attach a token if an auth plugin is available).
available_versions(**kwargs)

Return a list of identity APIs available on the server.

The list returned includes the data associated with them.

Warning

This method is deprecated as of the 1.7.0 release in favor of raw_version_data() and may be removed in the 2.0.0 release.

Parameters:

create_client(version=None, unstable=False, **kwargs)

Factory function to create a new identity service client.

Parameters:
  • version (tuple) – The required version of the identity API. If specified the client will be selected such that the major version is equivalent and an endpoint provides at least the specified minor version. For example to specify the 3.1 API use (3, 1). (optional)

keystoneclient.discover.add_catalog_discover_hack(service_type, old, new)

Add a version removal rule for a particular service.

Originally deployments of OpenStack would contain a versioned endpoint in the catalog for different services. E.g. an identity service might look like http://localhost:5000/v2.0. This is a problem when we want to use a different version like v3.0 as there is no way to tell where it is located. We cannot simply change all service catalogs either so there must be a way to handle the older style of catalog.

This function adds a rule for a given service type that if part of the URL matches a given regular expression in old then it will be replaced with the new value. This will replace all instances of old with new. It should therefore contain a regex anchor.

For example the included rule states:

add_catalog_version_hack('identity', re.compile('/v2.0/?$'), '/')

so if the catalog retrieves an identity URL that ends with /v2.0 or /v2.0/ then it should replace it simply with / to fix the user’s catalog.

Parameters:
  • service_type (str) – The service type as defined in the catalog that the rule will apply to.
  • old (re.RegexObject) – The regular expression to search for and replace if found.
  • new (str) – The new string to replace the pattern with.
keystoneclient.discover.available_versions(url, session=None, **kwargs)

Retrieve raw version data from a url.

keystoneclient.discover.normalize_version_number(version)

Turn a version representation into a tuple.

Takes a string, tuple or float which represent version formats we can handle and converts them into a (major, minor) version tuple that we can actually use for discovery.

e.g. ‘v3.3’ gives (3, 3)
3.1 gives (3, 1)
Parameters:version – Inputted version number to try and convert.
Returns:A usable version tuple
Return type:tuple
Raises:TypeError – if the inputted version cannot be converted to tuple.
keystoneclient.discover.version_match(required, candidate)

Test that an available version satisfies the required version.

To be suitable a version must be of the same major version as required and be at least a match in minor/patch level.

eg. 3.3 is a match for a required 3.1 but 4.1 is not.

Parameters:
  • required (tuple) – the version that must be met.
  • candidate (tuple) – the version to test against required.
Returns:

True if candidate is suitable False otherwise.
Return type:

bool

Authenticate user.

Uses the data provided at instantiation to authenticate against the Identity server. This may use either a username and password or token for authentication. If a tenant name or id was provided then the resulting authenticated client will be scoped to that tenant and contain a service catalog of available endpoints.

With the v2.0 API, if a tenant name or ID is not provided, the authentication token returned will be ‘unscoped’ and limited in capabilities until a fully-scoped token is acquired.

With the v3 API, if a domain name or id was provided then the resulting authenticated client will be scoped to that domain. If a project name or ID is not provided, and the authenticating user has a default project configured, the authentication token returned will be ‘scoped’ to the default project. Otherwise, the authentication token returned will be ‘unscoped’ and limited in capabilities until a fully-scoped token is acquired.

With the v3 API, with the OS-TRUST extension enabled, the trust_id can be provided to allow project-specific role delegation between users

If successful, sets the self.auth_ref and self.auth_token with the returned token. If not already set, will also set self.management_url from the details provided in the token.

Returns:

True if authentication was successful.
Raises:

If keyring is used, token is retrieved from keyring instead. Authentication will only be necessary if any of the following conditions are met:

  • keyring is not used
  • if token is not found in keyring
  • if token retrieved from keyring is expired or about to expired (as determined by stale_duration)
  • if force_new_token is true

classmethod construct(kwargs)

Handle constructing a session from both old and new arguments.

Support constructing a session from the old HTTPClient args as well as the new request-style arguments.

Warning

DEPRECATED as of 1.7.0: This function is purely for bridging the gap between older client arguments and the session arguments that they relate to. It is not intended to be used as a generic Session Factory. This function may be removed in the 2.0.0 release.

This function purposefully modifies the input kwargs dictionary so that the remaining kwargs dict can be reused and passed on to other functions without session arguments.

delete(url, **kwargs)

Perform a DELETE request.

This calls request() with method set to DELETE.

get(url, **kwargs)

Perform a GET request.

This calls request() with method set to GET.

get_auth_connection_params(auth=None, **kwargs)

Return auth connection params as provided by the auth plugin.

An auth plugin may specify connection parameters to the request like providing a client certificate for communication.

We restrict the values that may be returned from this function to prevent an auth plugin overriding values unrelated to connection parameters. The values that are currently accepted are:

  • cert: a path to a client certificate, or tuple of client certificate and key pair that are used with this request.
  • verify: a boolean value to indicate verifying SSL certificates against the system CAs or a path to a CA file to verify with.

These values are passed to the requests library and further information on accepted values may be found there.

Parameters:

auth (keystoneclient.auth.base.BaseAuthPlugin) – The auth plugin to use for tokens. Overrides the plugin on the session. (optional)
Raises:
Returns:

Authentication headers or None for failure.
Return type:

dict

Send an HTTP request with the specified characteristics.

Wrapper around requests.Session.request to handle tasks such as setting headers, JSON encoding/decoding, and error handling.

Arguments that are not handled are passed through to the requests library.

Parameters:
  • url (string) – Path or fully qualified URL of HTTP request. If only a path is provided then endpoint_filter must also be provided such that the base URL can be determined. If a fully qualified URL is provided then endpoint_filter will be ignored.
  • method (string) – The http method to use. (e.g. ‘GET’, ‘POST’)
  • original_ip (string) – Mark this request as forwarded for this ip. (optional)
  • headers (dict) – Headers to be included in the request. (optional)

  • auth (keystoneclient.auth.base.BaseAuthPlugin) – The auth plugin to use when authenticating this request. This will override the plugin that is attached to the session (if any). (optional)
  • requests_auth (requests.auth.AuthBase) – A requests library auth plugin that cannot be passed via kwarg because the auth kwarg collides with our own auth plugins. (optional)
  • raise_exc (bool) – If True then raise an appropriate exception for failed HTTP requests. If False then return the request object. (optional, default True)
  • allow_reauth (bool) – Allow fetching a new token and retrying the request on receiving a 401 Unauthorized response. (optional, default True)
  • log (bool) – If True then log the request and response data to the debug log. (optional, default True)
  • logger (logging.Logger) – The logger object to use to log request and responses. If not provided the keystoneclient.session default logger will be used.
  • kwargs – any other parameter that can be passed to requests.Session.request (such as headers). Except: ‘data’ will be overwritten by the data in ‘json’ param. ‘allow_redirects’ is ignored as redirects are handled by the session.
Raises:
