尽管在“boot_command”中指定了“autoinstall”，Packer Ubuntu Server 20.04 仍提示安装确认

我正在使用 为 Ubuntu Server 20.04 设置无人值守安装packer。但是，尽管我autoinstall在 中指定了boot_command，安装程序总是要求我确认（我需要手动输入“是”-在屏幕截图中间）： 在此处输入图片描述

这显然违背了“无人值守安装”的概念，但我无法弄清楚问题出在哪里。我在下面发布了boot_command我正在使用的两个不同的系统，并在帖子末尾发布了我的完整配置。

两个启动命令都会生成一个有效的安装，但仍需要确认。启动命令 1：

boot_command = ["<enter><wait2><enter><wait><f6><esc><wait>", "autoinstall<wait2> ds=nocloud;", "<wait><enter>"]

启动命令2：

      "boot_command": [
        "<enter><wait2><enter><wait><f6><esc><wait>",
        "linux /casper/vmlinuz autoinstall ds=nocloud;",
        "<wait><enter>",
        "initrd /casper/initrd",
        "<wait><enter>",
        "boot"
      ],

答案1

我遇到了同样的问题，并在控制台上注意到 Packer 在安装程序准备好之前输入了“yes”（安装程序在 200 秒后暂停，但 boot_wait 设置为 180）。我增加了“boot_wait”值来纠正这个问题（见下文）。还显示了两个额外的超时设置，您可能需要（或不需要）调整它们：

  • boot_wait =“300秒”

  • ip_wait_timeout =“20米”

  • ssh_timeout=“30米”
