## 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, …)
