OpenStack Functions Client Library
|
|
|
|
This is a client library for Project LaOS built on the Project LaOS API. It
|
|
provides a Python API (the ``picassoclient`` module).
|
|
|
|
The project is hosted on `Launchpad`_, where bugs can be filed. The code is
|
|
hosted on `Github`_. Patches must be submitted using `Gerrit`_, *not* Github
|
|
pull requests.

Install the client from PyPI
|
|
----------------------------
|
|
The :program:`python-picassoclient` package is published on `PyPI`_ and
|
|
so can be installed using the pip tool, which will manage installing all
|
|
python dependencies::
|
|
|
|
$ pip install python-picassoclient
|
|
|
|
.. note::
|
|
The packages on PyPI may lag behind the git repo in functionality.
|
|
|
|
.. _PyPI: https://pypi.python.org/pypi/python-picassoclient/
|
|
|
|
Setup the client from source
|
|
----------------------------
|
|
|
|
* Clone repository for python-picassoclient::
|
|
|
|
$ git clone https://github.com/iron-io/python-picassoclient.git
|
|
$ cd python-picassoclient
|
|
|
|
* Setup a virtualenv
|
|
|
|
.. note::
|
|
This is an optional step, but will allow picassoclient's dependencies
|
|
to be installed in a contained environment that can be easily deleted
|
|
if you choose to start over or uninstall picassoclient.
|
|
|
|
::
|
|
|
|
$ tox -evenv --notest
|
|
|
|
Activate the virtual environment whenever you want to work in it.
|
|
All further commands in this section should be run with the venv active:
|
|
|
|
::
|
|
|
|
$ source .tox/venv/bin/activate
|
|
|
|
.. note::
|
|
When ALL steps are complete, deactivate the virtualenv: $ deactivate
|
|
|
|
* Install picassoclient and its dependencies::
|
|
|
|
(venv) $ python setup.py develop
|
|
|
|
Command-line API
|
|
----------------
|
|
|
|
Set Keystone environment variables to execute CLI commands against LaOS.
|
|
|
|
* To execute CLI commands::
|
|
|
|
$ export OS_USERNAME=<user>
|
|
$ export OS_PASSWORD=<password>
|
|
$ export OS_PROJECT_NAME=<project>
|
|
$ export OS_AUTH_URL=http://localhost:5000/v3
|
|
|
|
.. note::
|
|
With devstack you just need to $ source openrc <user> <project>. And you can
|
|
work with a local installation by passing --os-token <TOKEN> and --os-url
|
|
http://localhost:9393. You can also set up a `Openstackclient`_ config file
|
|
to work with the CLI.
|
|
|
|
.. _Openstackclient: http://docs.openstack.org/developer/python-openstackclient/configuration.html#clouds-yaml
|
|
|
|
::
|
|
|
|
$ openstack
|
|
(openstack) fn-apps list
|
|
(openstack) fn-apps create testapp
|

|
Python API
|
|
----------
|
|
|
|
To use with keystone as the authentication system::
|
|
|
|
>>> from keystoneclient.auth.identity import generic
|
|
>>> from keystoneclient import session
|
|
>>> from picassoclient import client
|
|
>>> auth = generic.Password(auth_url=OS_AUTH_URL, username=OS_USERNAME, password=OS_PASSWORD, tenant_name=OS_TENANT_NAME)
|
|
>>> keystone_session = session.Session(auth=auth)
|
|
>>> picasso = client.Client('v1', session=keystone_session)
|
|
>>> picasso.apps.list()
|

Testing
|
|
-------
|
|
|
|
There are multiple test targets that can be run to validate the code.
|
|
|
|
* tox -e pep8 - style guidelines enforcement
|
|
* tox -e py34 - traditional unit testing
|
|
* tox -e py35 - traditional unit testing
