Constructor Details

This class inherits a constructor from Kitchen::Provisioner::Base

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:

Examples:

overriding #create_sandbox


class MyProvisioner < Kitchen::Provisioner::Base
  def create_sandbox
    super
    # any further file copies, preparations, etc.
  end
end

def create_sandbox
  super
  prepare_chef_client_zero_rb
  prepare_validation_pem
  prepare_client_rb
end

#prepare_command ⇒ String

Generates a command string which will perform any commands or configuration required just before the main provisioner run command but after the sandbox has been transferred to the instance. If no work is required, then nil will be returned.

Returns:

  • (String) —

    a command string

#run_command ⇒ String

Generates a command string which will invoke the main provisioner command on the prepared instance. If no work is required, then nil will be returned.

Returns:
