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',
+    )
+)
+
+

Patches welcome for any cloud
