我正在尝试进行打包程序构建。

我的源 AMI 是一个 Ubuntu 盒子。我想安装并运行一个 python 虚拟环境。

我的供应商如下所示。apt-get 工作正常，它创建了一个 virtualenv。但是，当我激活源时，它失败了。我收到以下错误：/tmp/script.sh: 53: /tmp/script.sh

看来我无法source在我的打包程序版本中运行。我该如何解决这个问题？我需要运行 virtualenv 并pip install从里面做。

  "provisioners": [

    {
      "type": "shell",
      "inline": [
        "echo '70'",
        "sudo apt-get --assume-yes install python-virtualenv",
        "echo '80'",
        "sudo virtualenv /home/myuser/myVirtualEnv",
        "echo '90'",
        "ls -altr /home/myuser/myVirtualEnv/bin",
        "echo '95'",
        "source /home/myuser/myVirtualEnv/bin/activate",
        "echo '100'",
      ]
    }
  ]

这是控制台输出：

请注意此处的疑难解答部分中有关 shell 脚本的注释。默认情况下，packer 使用 /bin/sh，它在 Ubuntu 上是 dash shell。dash shell 不支持“source”命令。相反，您可以：

  • 采用 ”。” 而不是源
  • 在您的打包程序文件中指定 inline_shebang
  • 使用“脚本”而不是“内联”

您只能在没有的 shell 中获取资源。无论如何，有一个更简单的解决方案，直接使用 virtualenv 中为您提供的二进制文件。

$ virtualenv foobarbaz
$ foobarbaz/bin/python -c 'import sys; print sys.prefix;'

说明了这个概念 & 将以与 pip 相同的方式工作。

Packer 构建 HCL 文件：

build {
  provisioner "shell" {
    script = "../scripts/setup.sh"
  }
}

并在 setup.sh 中替换source为.：

#!/bin/bash

. env/bin/activate
