Notes

Note

• The following environment variables can be used, RAX_USERNAME, RAX_API_KEY, RAX_CREDS_FILE, RAX_CREDENTIALS, RAX_REGION.

• RAX_CREDENTIALS and RAX_CREDS_FILE points to a credentials file appropriate for pyrax. See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating

• RAX_USERNAME and RAX_API_KEY obviate the use of a credentials file

• RAX_REGION defines a Rackspace Public Cloud region (DFW, ORD, LON, …)

• The following environment variables can be used, RAX_USERNAME, RAX_API_KEY, RAX_CREDS_FILE, RAX_CREDENTIALS, RAX_REGION.
