由于sudo需要tty,Packer构建失败

时间:2015-08-03 13:40:20

标签: vagrant virtualbox sudo packer

我的打包程序构建失败,显示以下消息:

sudo: sorry, you must have a tty to run sudo.

我的主机是带有vagrant和virtualbox的Windows 8,我的客人是centos7。 在研究它是我的理解,不要求suty的tty是消息的原因。但我在ks.cfg中有以下内容:

sed -i 's/^.*requiretty/#Defaults requiretty/' /etc/sudoers

问题可能是我需要在windows vagrant ssh端设置一些东西,以便创建一个伪造的东西吗?

这是我第一次去打包机。

我正在使用我下载的打包器版本。

packer.json下面:

  "variables": {
    "version": "{{env `VERSION`}}"
  },

      ]
    }
  ],

    {

  ]
}

提前致谢。

您必须在ssh连接中启用PTY。在配置项后面添加构建器部分:

"ssh_pty" : "true"

另见https://packer.io/docs/templates/communicator.html#ssh_pty

你的&#34; execute_command&#34;在供应者部分应为"execute_command" : "echo 'vagrant' | {{ .Vars }} sudo -E -S sh '{{ .Path }}'"

对于类似的错误消息 - “sudo:no tty present并且没有指定askpass程序” - 我在本文中找到了解决方案:

除了在构建器部分添加"ssh_pty" : "true"之外,还要添加以下配置程序:

{
  "type": "shell",
  "execute_command": "echo '{{user `ssh_pass`}}' | {{ .Vars }} sudo -E -S sh '{{ .Path }}'",
  "inline": [
    "echo '%sudo    ALL=(ALL)  NOPASSWD:ALL' >> /etc/sudoers"
  ]
}
