如何自动将主机的SSH公钥迁移到基于Puppet的Vagrant虚拟机

config.vm.provision "shell", inline: <<-SHELL
  echo '添加主机公钥到authorized_keys文件'
  echo 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDL...' >> /home/vagrant/.ssh/authorized_keys
SHELL

class ssh_keys {
  ssh_authorized_key { 'vagrant':
    user      => 'vagrant',
    type      => 'ssh-rsa',
    key       => 'AAAAB3NzaC1yc2EAAAADAQABAAABAQDL...',
    ensure    => present,
    require   => File['/home/vagrant/.ssh'],
  }
}

config.vm.provision "puppet" do |puppet|
  puppet.manifests_path = "manifests"
  puppet.manifest_file  = "site.pp"
  puppet.module_path    = "modules"
end
