Packer shell provisioner报告成功运行，但没有做任何事情

Question

我试图使用packer简单地启动一个VM，运行一个shell脚本，然后存储一个新的映像。我使用Azure，当我运行packer时，它似乎成功地完成了，但是当我从新映像生成VM时，脚本似乎没有效果。该脚本仅用于测试，应该在主目录中创建一个文件，但当我登录时，没有任何内容。

下面是我的packer配置文件：

 {
   "builders": [
     {
       "type": "azure-arm",

       "client_id": "...",
       "client_secret": "...",
       "subscription_id": "...",
       "tenant_id": "...",

       "os_type": "Linux",
       "image_publisher": "Canonical",
       "image_offer": "UbuntuServer",
       "image_sku": "16.04-LTS",

       "ssh_pty" : "true",

       "capture_container_name": "container",
       "capture_name_prefix": "prefix",
       "resource_group_name": "rg",
       "storage_account": "sa",

       "location": "West US"
     }
   ],
   "provisioners": [
     {
       "type": "shell",
       "script": "test.sh"
     }
   ]
 }

下面是我的脚本(test.sh)：

#!/bin/bash -e
echo "This is only a test!" >> ~/test_script_output.txt

这是构建的输出：

azure-arm output will be in this color.

好吧，我有两件事是任务。

第一，我必须用waagent解除，这样VM才能正确启动。显然，这是天蓝色臂型的要求。。第二:现在用户帐户被删除了，我不得不更改脚本以影响主目录之外的内容。所以我让它在驱动器根目录上创建一个新文件。

这是我的新的供应科：

"provisioners": [
  {
    "type": "shell",
    "execute_command": "chmod +x {{ .Path }}; {{ .Vars }} sudo '{{ .Path }}'",
    "script": "test.sh",
    "skip_clean": "true"
  },
  {
    "type": "shell",
    "execute_command": "chmod +x {{ .Path }}; {{ .Vars }} sudo -E sh '{{ .Path }}'",
    "inline_shebang": "/bin/sh -x",
    "inline": [
      "/usr/sbin/waagent -force -deprovision+user && export HISTSIZE=0 && sync"
    ],
    "skip_clean": "true"
  }
]

这是我的新剧本：

#!/bin/bash -e
echo "This is only a test!" >> /test_script_output.txt

附带注意:我不得不在每个提供程序中添加"skip_clean“，因为它每次都不会删除脚本。我还不知道为什么。
