OpenStack Client
|
|
================
|
|
|
|
OpenStack Client (aka ``python-openstackclient``) is a command-line client for
|
|
the OpenStack APIs.
|
|
It is primarily a wrapper to the stock python-\*client modules that implement the
|
|
actual REST API client actions.
|
|
|
|
This is an implementation of the design goals shown in
|
|
`OpenStack Client Wiki`_. The primary goal is to provide
|
|
a unified shell command structure and a common language to describe
|
|
operations in OpenStack. The master repository is on GitHub_.
|
|

|
.. _GitHub: https://github.com/openstack/python-openstackclient
|
|
|
|
OpenStack Client has a plugin mechanism to add support for API extensions.

Note
|
|
====
|
|
|
|
OpenStackClient is considered to be beta release quality as of the 0.3 release;
|
|
no assurances are made at this point for ongoing compatibility in command forms
|
|
or output. We do not, however, expect any major changes at this point.
|
|
|
|
Getting Started
|
|
===============
|
|
|
|
OpenStack Client can be installed from PyPI using pip::
|
|
|
|
pip install python-openstackclient
|
|
|
|
Developers can use the `install virtualenv`_ script to create the virtualenv::
|
|
|
|
python tools/install_venv.py
|
|
source .venv/bin/activate
|
|
python setup.py develop
|
|
|
|
Unit tests are now run using tox. The ``run_test.sh`` script provides compatibility
|
|
but is generally considered deprecated.
|
|
|
|
The client can be called interactively by simply typing::
|
|
|
|
openstack
|
|
|
|
There are a few variants on getting help. A list of global options and supported
|
|
commands is shown with ``--help``::
|
|
|
|
openstack --help
|
|
|
|
There is also a ``help`` command that can be used to get help text for a specific
|
|
command::
|
|
|
|
openstack help
|
|
openstack help server create
|
|
|
|
Configuration
|
|
=============
|
|
|
|
The CLI is configured via environment variables and command-line
|
|
options as listed in https://wiki.openstack.org/wiki/OpenStackClient/Authentication.
|
|
|
|
The 'password flow' variation is most commonly used::
|
|
|
|
export OS_AUTH_URL=<url-to-openstack-identity>
|
|
export OS_PROJECT_NAME=<project-name>
|
|
export OS_USERNAME=<user-name>
|
|
export OS_PASSWORD=<password> # (optional)
|
|
|
|
The corresponding command-line options look very similar::
|
|
|
|
--os-auth-url <url>
|
|
--os-project-name <project-name>
|
|
--os-username <user-name>
|
|
[--os-password <password>]
|
|
|
|
If a password is not provided above (in plaintext), you will be interactively
|
|
prompted to provide one securely.
|
|
|
|
The token flow variation for authentication uses an already-acquired token
|
|
and a URL pointing directly to the service API that presumably was acquired
|
|
from the Service Catalog::
|
|
|
|
export OS_TOKEN=<token>
|
|
export OS_URL=<url-to-openstack-service>
|
|
|
|
The corresponding command-line options look very similar::
|
|
|
|
--os-token <token>
|
|
--os-url <url-to-openstack-service>
|
|
|
|
Additional command-line options and their associated environment variables
|
|
are listed here::
|
|
|
|
--debug # turns on some debugging of the API conversation
|
|
--verbose | -v # Increase verbosity of output. Can be repeated.
|
|
--quiet | -q # suppress output except warnings and errors
|
|
--help | -h # show a help message and exit
|

Building Documentation
|
|
======================
|
|
|
|
This documentation is written by contributors, for contributors.
|
|
|
|
The source is maintained in the ``doc/source`` folder using
|
|
`reStructuredText`_ and built by `Sphinx`_
|
|
|
|
.. _reStructuredText: http://docutils.sourceforge.net/rst.html
|
|
.. _Sphinx: http://sphinx.pocoo.org/
|
|
|
|
Building Manually::
|
|
|
|
cd doc
|
|
make html
|
|
|
|
Results are in the ``build/html`` directory.
