通过 Vagrantfile 中的循环创建具有多个磁盘的虚拟机

通过 Vagrantfile 中的循环创建具有多个磁盘的虚拟机

我正在尝试使用 vagrant 创建具有多个磁盘的虚拟机，但我希望 vagrantfile 使用循环来创建它们。Vagrant 无法正确处理循环，因为它似乎要重复两次或三次循环。然后 Vagrant 失败，因为它已经创建了 disk1.vdi

警告：我不是 Ruby 专家......

我尝试过使用数组和 ruby​​ 的 .each 方法。尝试过 while 循环。全部失败，出现相同问题。

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.provider "virtualbox" do |v|
          Drives = [1,2,3,4,5]
          Drives.each do |hd|
                puts "harddrive #{hd}"
                v.customize ['createhd', '--filename', "./disk#{hd}.vdi",'--variant', 'Fixed', '--size', 20 * 1024]
                v.customize ['storageattach', :id,  '--storagectl', 'IDE', '--device', hd+1, '--type', 'hdd', '--medium', "./disk#{hd}.vdi"]  
          end
  end

end

我期望虚拟机有 5+1 个驱动器

我得到的是

Please fix this customization and try again.

更改以下内容：

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.provider "virtualbox" do |v|
          Drives = [1,2,3,4,5]
          Drives.each do |hd|
                puts "harddrive #{hd}"
                v.customize ['createhd', '--filename', "./disk#{hd}.vdi",'--variant', 'Fixed', '--size', 20 * 1024]
                v.customize ['storageattach', :id,  '--storagectl', 'IDE', '--port', hd, '--device', 0, '--type', 'hdd', '--medium', "./disk#{hd}.vdi"]  
          end
  end

end

请注意这一行：

v.customize ['storageattach', :id, '--storagectl', 'IDE', '--port', hd, '--device', 0, '--type', 'hdd', '--medium', "./disk#{hd}.vdi"]

--device：已设置为 0 --port：已设置为 hd 索引（1，然后是 2，然后是 3，然后是 4，然后是 5）

远离--port 0，因为它通常是启动盘。
