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',

Patches welcome for any cloud
