Method: Inspec::Config#unpack_train_credentials

Defined in:
lib/inspec/config.rb

#unpack_train_credentials ⇒ Object

Returns a Hash with Symbol keys as follows:

backend: machine name of the Train transport needed
If present, any of the GENERIC_CREDENTIALS.
All other keys are specific to the backend.

The credentials are gleaned from:

* the Train transport defaults. Train handles this on transport creation,
    so this method doesn't load defaults.
* individual InSpec CLI options (which in many cases may have the
    transport name prefixed, which is stripped before being added
    to the creds hash)
* the --target CLI option, which is interpreted:
   - as a transport://credset format, which looks up the creds in
     the config file in the credentials section
   - as an arbitrary URI, which is parsed by Train.unpack_target_from_uri
