linux - Packer Amazon EBS Chef - 抱歉，您必须有 tty 才能运行 sudo

Question

我想使用 Packer用于使用 Chef 为亚马逊 ebs 配置图像。

我收到以下错误消息:

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

例子.json

{
  "builders": [{
    "type": "amazon-ebs",
    "access_key": "...",
    "secret_key": "...",
    "region": "eu-central-1",
    "source_ami": "ami-daaeaec7",
    "instance_type": "t2.micro",
    "ssh_username": "ec2-user",
    "ami_name": "packer-example {{timestamp}}"
  }],
  "provisioners": [{
    "type": "chef-solo",
    "cookbook_paths": ["cookbooks", "site-cookbooks"],
    "run_list": [  ]
  }]
}

输出

$ packer build example.json
amazon-ebs output will be in this color.

==> Some builds didn't complete successfully and had errors:
--> amazon-ebs: Error installing Chef: Install script exited with non-zero exit status 1

==> Builds finished but no artifacts were created.

我认为相关的错误信息是:

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

有人有想法吗？

Answer 1

您可以使用 ssh_pty : true 来获得 TTY。

{
   "builders": [{
      ...
      "ssh_pty" : true,
      ...
    }],
    ...
}
