shade 1.33.0

Description:

shade 1.33.0

Introduction

Warning
shade has been superceded by openstacksdk and no longer takes new
features. The existing code will continue to be maintained indefinitely
for bugfixes as necessary, but improvements will be deferred to
openstacksdk. Please update your applications to use openstacksdk
directly.

shade is a simple client library for interacting with OpenStack clouds. The
key word here is simple. Clouds can do many many many things - but there are
probably only about 10 of them that most people care about with any
regularity. If you want to do complicated things, you should probably use
the lower level client libraries - or even the REST API directly. However,
if what you want is to be able to 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 narcissist peers, then shade is for you.
shade started its life as some code inside of ansible. ansible has a bunch
of different OpenStack related modules, and there was a ton of duplicated
code. Eventually, between refactoring that duplication into an internal
library, and adding logic and features that the OpenStack Infra team had
developed to run client applications at scale, it turned out that we’d written
nine-tenths of what we’d need to have a standalone library.


Example
Sometimes an example is nice.

Create a clouds.yml file:
clouds:
mordred:
region_name: RegionOne
auth:
username: 'mordred'
password: XXXXXXX
project_name: 'shade'
auth_url: 'https://montytaylor-sjc.openstack.blueboxgrid.com:5001/v2.0'
Please note: os-client-config will look for a file called clouds.yaml
in the following locations:

Current Directory
~/.config/openstack
/etc/openstack

More information at https://pypi.org/project/os-client-config

Create a server with shade, configured with the clouds.yml file:
import shade

# Initialize and turn on debug logging
shade.simple_logging(debug=True)

# Initialize cloud
# Cloud configs are read with os-client-config
cloud = shade.openstack_cloud(cloud='mordred')

# Upload an image to the cloud
image = cloud.create_image(
'ubuntu-trusty', filename='ubuntu-trusty.qcow2', wait=True)

# Find a flavor with at least 512M of RAM
flavor = cloud.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.
cloud.create_server(
'my-server', image=image, flavor=flavor, wait=True, auto_ip=True)
