Constructor Details
#initialize(config = {}) ⇒ ChefBase
Reads the local Chef::Config object (if present). We do this because we want to start bring Chef config and ChefDK tool config closer together. For example, we want to configure proxy settings in 1 location instead of 3 configuration files.

Instance Method Details
#create_sandbox ⇒ Object
Creates a temporary directory on the local workstation into which provisioner related files and directories can be copied or created. The contents of this directory will be copied over to the instance before invoking the provisioner's run command. After this method completes, it is expected that the contents of the sandbox is complete and ready for copy to the remote instance.
Note: any subclasses would be well advised to call super first when overriding this method, for example:

# File 'lib/kitchen/provisioner/chef_base.rb', line 157 def create_sandbox super Chef::CommonSandbox.new(config, sandbox_path, instance).populate end |
#init_command ⇒ String
Generates a command string which will perform any data initialization
or configuration required after the provisioner software is installed
but before the sandbox has been transferred to the instance. If no work
is required, then nil
will be returned.
