Monty Taylor a99d6f1912 Rename BaseProxy to Proxy

The base resource class is "Resource" but the base proxy class is
"BaseProxy" which makes reading the docs a bit strange. It was
originally not really a big real because nothing used Proxy directly.
But since we add Proxy instances to the Connection for every service in
service-types-authority which are now documented as part of the
Connection object, calling them BaseProxy is a bit weird.

Keep a BaseProxy object around so we don't break out of tree Proxy
objects, but add a deprecation to it so people can update.

Shift BaseProxy from the main user docs to the contributor layout docs.
Add showing inheritance, as well as docs for OpenStackSDKAdapter.

Getting started with the OpenStack SDK

For a listing of terms used throughout the SDK, including the names of projects and services supported by it, see the glossary <../glossary>.

Installation

The OpenStack SDK is available on PyPI under the name openstacksdk. To install it, use pip:

$ pip install openstacksdk

User Guides

These guides walk you through how to make use of the libraries we provide to work with each OpenStack service. If you're looking for a cookbook approach, this is where you'll want to begin.

API Documentation

Service APIs are exposed through a two-layered approach. The classes exposed through our Connection interface are the place to start if you're an application developer consuming an OpenStack cloud. The Resource interface is the layer upon which the Connection is built, with Connection methods accepting and returning Resource objects.

The Cloud Abstraction layer has a data model.

Connection Interface

A Connection instance maintains your cloud config, session and authentication information providing you with a set of higher-level interfaces to work with OpenStack services.

connection

Once you have a Connection instance, services are accessed through instances of ~openstack.proxy.Proxy or subclasses of it that exist as attributes on the ~openstack.connection.Connection.

Service Proxies

The following service proxies exist on the ~openstack.connection.Connection. The service proxies are all always present on the ~openstack.connection.Connection object, but the combination of your CloudRegion and the catalog of the cloud in question control which services can be used.

Baremetal <proxies/baremetal> Block Storage <proxies/block_storage> Clustering <proxies/clustering> Compute <proxies/compute> Database <proxies/database> Identity v2 <proxies/identity_v2> Identity v3 <proxies/identity_v3> Image v1 <proxies/image_v1> Image v2 <proxies/image_v2> Key Manager <proxies/key_manager> Load Balancer <proxies/load_balancer_v2> Message v2 <proxies/message_v2> Network <proxies/network> Object Store <proxies/object_store> Orchestration <proxies/orchestration> Workflow <proxies/workflow>

Resource Interface

The Resource layer is a lower-level interface to communicate with OpenStack services. While the classes exposed by the Connection build a convenience layer on top of this, Resources can be used directly. However, the most common usage of this layer is in receiving an object from a class in the Connection layer, modifying it, and sending it back into the Connection layer, such as to update a resource on the server.

The following services have exposed Resource classes.

Baremetal <resources/baremetal/index> Block Storage <resources/block_storage/index> Clustering <resources/clustering/index> Compute <resources/compute/index> Database <resources/database/index> Identity <resources/identity/index> Image <resources/image/index> Key Management <resources/key_manager/index> Load Balancer <resources/load_balancer/index> Network <resources/network/index> Orchestration <resources/orchestration/index> Object Store <resources/object_store/index> Workflow <resources/workflow/index>

Low-Level Classes

The following classes are not commonly used by application developers, but are used to construct applications to talk to OpenStack APIs. Typically these parts are managed through the Connection Interface, but their use can be customized.
