===========
Compute API
===========
The nova project has a RESTful HTTP service called the OpenStack Compute API.
Through this API, the service provides massively scalable, on demand,
self-service access to compute resources. Depending on the deployment those
compute resources might be Virtual Machines, Physical Machines or Containers.
This guide covers the concepts in the OpenStack Compute API.
For a full reference listing, please see:
`Compute API Reference <https://docs.openstack.org/api-ref/compute/#compute-api>`__.
We welcome feedback, comments, and bug reports at
`bugs.launchpad.net/nova <https://bugs.launchpad.net/nova>`__.
Intended audience
=================
This guide assists software developers who want to develop applications
using the OpenStack Compute API. To use this information, you should
have access to an account from an OpenStack Compute provider, or have
access to your own deployment, and you should also be familiar with the
following concepts:
* OpenStack Compute service
* RESTful HTTP services
* HTTP/1.1
* JSON data serialization formats
End User and Operator APIs
==========================
The Compute API includes all end user and operator API calls.
The API works with keystone and oslo.policy to deliver RBAC (Role-based access
control).
The default policy file gives suggestions on what APIs should not
be made available to most end users but this is fully configurable.
API Versions
============
Following the Mitaka release, every Nova deployment should have
the following endpoints:
* / - list of available versions
* /v2 - the first version of the Compute API, uses extensions
(we call this Compute API v2.0)
* /v2.1 - same API, except uses microversions
While this guide concentrates on documenting the v2.1 API,
please note that the v2.0 is (almost) identical to first microversion of
the v2.1 API and are also covered by this guide.
