|

author: Matt Martz
|
||||
notes:
|
||||
- The following environment variables can be used, C(RAX_USERNAME),
|
||||
C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
|
||||
- C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
|
||||
appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
|
||||
- C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
|
||||
- C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
