I'm awash in cloud accounts

Infra has 5
- control plane and nodepool in 3 Rackspace regions
- control plane and nodepool in HP
two personal on HP and one on Rackspace
two internal HP accounts
That's 12 OpenStack cloud-regions

- -

- How do I connect to them? -

- -

- List Servers -

-openstack \
-        --auth-url=https://region-b.geo-1.identity.hpcloudsvc.com:35357/v2.0 \
-        --username=mordred@inaugust.com \
-        --password=XXXXXX \
-        --project-name=mordred@inaugust.com \
-        --region-name=region-b.geo-1 \
-    server list
-

- Well that's silly -

- -

- Consistent Environment Variables -

-export OS_AUTH_URL=https://region-b.geo-1.identity.hpcloudsvc.com:35357/v2.0
-export OS_USERNAME=mordred@inaugust.com
-export OS_PASSWORD=XXXXXXXXXXXXX
-export OS_TENANT_NAME=mordred@inaugust.com
-export OS_REGION_NAME=region-b.geo-1

- 12 shell script snippet files -

- -

- ENV processing is in command line tools, not client libraries -

- -

- ENV processing is just copied everywhere -

-$ egrep -r 'add_(option|argument).*os-username' openstack/python*client | wc -l
-13
-

- -

Pre-existing knowledge

auth-url
glance API version
override settings
- URLs (swift URL in rackspace keystone catalog is wrong)
- service types (DNS in HP is hpext:dns)

- -

I wrote a library (yay!)

os-client-config

- -

Processes, in this order

config file: clouds.yaml
env vars
command line args

- -

Provides vendor defaults

-CLOUD_DEFAULTS = dict(
-    hp=dict(
-        auth_url='https://region-b.geo-1.identity.hpcloudsvc.com:35357/v2.0',
-        dns_service_type='hpext:dns',
-    ),
-    rackspace=dict(
-        auth_url='https://identity.api.rackspacecloud.com/v2.0/',
-        database_service_type='rax:database',
-        image_api_version='2',
