Notes¶
Note
- The following environment variables can be used, RAX_USERNAME,RAX_API_KEY,RAX_CREDS_FILE,RAX_CREDENTIALS,RAX_REGION.
- RAX_CREDENTIALSand- RAX_CREDS_FILEpoints to a credentials file appropriate for pyrax. See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating
- RAX_USERNAMEand- RAX_API_KEYobviate the use of a credentials file
- RAX_REGIONdefines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
