由于sudo需要tty,Packer构建失败

Question

我的打包器构建失败,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.但我有以下内容ks.cfg:

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

可能问题是我需要在Windows vagrant ssh端设置一些东西,以便创建一个伪造的tty？

这是我第一次去打包机.

我正在使用我下载的打包器构建.

packer.json如下:

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

      ]
    }
  ],

    }
  ]
}

提前致谢.

Answer 1

您必须在ssh连接中启用PTY.在配置项后面添加您的构建器部分:

"ssh_pty" : "true"

另请参见https://packer.io/docs/templates/communicator.html#ssh_pty

您在配置程序部分中的"execute_command"应该是 "execute_command" : "echo 'vagrant' | {{ .Vars }} sudo -E -S sh '{{ .Path }}'"

Answer 2

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:

http://blog.endpoint.com/2014/03/provisioning-development-environment_14.html

除了"ssh_pty" : "true"在构建器部分中添加外,还添加以下配置器:

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