openstacksdk is a client library for building applications to work
|
2017-10-04 18:06:22 +00:00
|
|
|
with OpenStack clouds. The project aims to provide a consistent and
|
|
|
|
complete set of interactions with OpenStack's many services, along with
|
|
|
|
complete documentation, examples, and tools.

It also contains an abstraction interface layer. Clouds can do many things, but
|
2017-10-04 18:06:22 +00:00
|
|
|
there are probably only about 10 of them that most people care about with any
|
|
|
|
regularity. If you want to do complicated things, the per-service oriented
|
2018-01-16 22:16:05 +00:00
|
|
|
portions of the SDK are for you. However, if what you want is to be able to
|
2017-10-04 18:06:22 +00:00
|
|
|
write an application that talks to clouds no matter what crazy choices the
|
|
|
|
deployer has made in an attempt to be more hipster than their self-entitled
|
2018-01-10 18:18:34 +00:00
|
|
|
narcissist peers, then the Cloud Abstraction layer is for you.

|
|
=========

|

|
|
List servers using objects configured with the ``clouds.yaml`` file:
|
|
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
|
|
|
|
import openstack
|
|
|
|
|
|
|
|
# Initialize and turn on debug logging
|
|
|
|
openstack.enable_logging(debug=True)
|
|
|
|
|
|
|
|
# Initialize cloud
|
|
|
|
conn = openstack.connect(cloud='mordred')
|
|
|
|
|
|
|
|
for server in conn.compute.servers():
|
|
|
|
print(server.to_dict())

Cloud Layer
|
|
|
|
===========
|
|
|
|
|
|
|
|
``openstacksdk`` contains a higher-level layer based on logical operations.
|
|
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
|
|
|
|
import openstack
|
|
|
|
|
|
|
|
# Initialize and turn on debug logging
|
|
|
|
openstack.enable_logging(debug=True)
|
|
|
|
|
|
|
|
for server in conn.list_servers():
|
|
|
|
print(server.to_dict())
|
|
|
|
|
|
|
|
The benefit is mostly seen in more complicated operations that take multiple
|
|
|
|
steps and where the steps vary across providers:
|
|
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
|
|
|
|
import openstack
|
|
|
|
|
|
|
|
# Initialize and turn on debug logging
|
|
|
|
openstack.enable_logging(debug=True)
|
|
|
|
|
|
|
|
# Initialize connection
|
|
|
|
# Cloud configs are read with openstack.config
|
|
|
|
conn = openstack.connect(cloud='mordred')
|
|
|
|
|
|
|
|
# Upload an image to the cloud
|
|
|
|
image = conn.create_image(
|
|
|
|
'ubuntu-trusty', filename='ubuntu-trusty.qcow2', wait=True)
|
|
|
|
|
|
|
|
# Find a flavor with at least 512M of RAM
|
|
|
|
flavor = conn.get_flavor_by_ram(512)
|
|
|
|
|
|
|
|
# Boot a server, wait for it to boot, and then do whatever is needed
|
|
|
|
# to get a public ip for it.
|
|
|
|
conn.create_server(
|
|
|
|
'my-server', image=image, flavor=flavor, wait=True, auto_ip=True)

openstack.config
|
|
|
|
================

``openstack.config`` will find cloud configuration for as few as 1 clouds and
|
|
|
|
as many as you want to put in a config file. It will read environment variables
|
|
|
|
and config files, and it also contains some vendor specific default values so
|
|
|
|
that you don't have to know extra info to use OpenStack
|
|
|
|
|
|
|
|
* If you have a config file, you will get the clouds listed in it
|
|
|
|
* If you have environment variables, you will get a cloud named `envvars`
|
|
|
|
* If you have neither, you will get a cloud named `defaults` with base defaults
|
|
|
|
|
|
|
|
Sometimes an example is nice.
|
|
|
|
|
|
|
|
Create a ``clouds.yaml`` file:
|
|
|
|
|
|
|
|
.. code-block:: yaml
|
|
|
|
|
|
|
|
clouds:
|
|
|
|
mordred:
|
|
|
|
region_name: Dallas
|
|
|
|
auth:
|
|
|
|
username: 'mordred'
|
|
|
|
password: XXXXXXX
|
|
|
|
project_name: 'shade'
|
|
|
|
auth_url: 'https://identity.example.com'
|
|
|
|
|
|
|
|
Please note: ``openstack.config`` will look for a file called ``clouds.yaml``
|
|
|
|
in the following locations:
|
|
|
|
|
|
|
|
* Current Directory
|
|
|
|
* ``~/.config/openstack``
|
|
|
|
* ``/etc/openstack``
