What are we going to talk about?

shade: a Python library to wrap business logic around OpenStack resources and operations

Design Principles

Current Status

https://git.openstack.org/cgit/openstack-infra/shade

https://pypi.python.org/pypi/shade

Why?

Brand experts insist that success comes from promoting your unique attributes, but in practice differentiation is less profitable than consolidation.

OpenStack Leaks Abstractions

OpenStack Breaks APIs

Basic concepts are needlessly complex

Client libraries are really for server-server communication

Infra solved these problems

Infra runs across 14 clouds at massive scale (20k servers per day)

Why not share what we've learned with other people?

simplicity

This is what using a cloud should look like


cloud = openstack_cloud('vexxhost')
image = cloud.create_image(
    'image-name', filename='image-filename.qcow2', wait=True)
flavor = cloud.get_flavor_by_ram(512)
cloud.create_server(
    'my-server', image=image, flavor=flavor, wait=True, auto_ip=True)
      

existence of shade is a bug

existence of shade is a feature

Using shade

Step One: Configuration

Caching and Rate Limiting

Cache Config

clouds.yaml


cache:
  class: dogpile.cache.dbm
  expiration_time: 3600
  arguments:
    filename: /home/mordred/.cache/openstack/shade.dbm
  expiration:
      server: 5
      

Caching Special Case

What if you're not a Python developer?
