As already stated above, a good way of reviewing the available options is by inspecting the output of the following API call:
curl https://<username>:<api_key>@api.softlayer.com/rest/v3/SoftLayer_Account/getCreateObjectOptions.json
Real issue is that I don't see a way though the config or code to pass further options to SL. Specifically, I'm most interested in setting privateNetworkOnlyFlag to True. But others will be required.
Your readme states:
(first off, that URL fails against softlayer. I believe the correct URL would be: https://${SL_USERNAME}:${SL_API_KEY}@api.softlayer.com/rest/v3/SoftLayer_Virtual_Guest/getCreateObjectOptions.json )
