type Config 

type Config struct {

	// in `/var/lib/lxc/containers/<container_name>`. Defaults to
	// `packer-<BuildName>`.
	ContainerName string `mapstructure:"container_name" required:"false"`
	// Allows you to specify a wrapper command, such
	// as ssh so you can execute packer builds on a remote host. Defaults to
	// `{{.Command}}`; i.e. no wrapper.
	CommandWrapper string `mapstructure:"command_wrapper" required:"false"`
	// The timeout in seconds to wait for the the
	// container to start. Defaults to 20 seconds.
	InitTimeout time.Duration `mapstructure:"init_timeout" required:"false"`

	// Options to pass to lxc-create. For

	// lxc-template command, usually located in
	// `/usr/share/lxc/templates/lxc-<template_name>`. Note: This gets passed as
	// ARGV to the template command. Ensure you have an array of strings, as a
	// single string with spaces probably won't work. Defaults to [].
	Parameters []string `mapstructure:"template_parameters" required:"false"`
	// Environmental variables to
	// use to build the template with.
	EnvVars []string `mapstructure:"template_environment_vars" required:"true"`
	// The minimum run level to wait for the
