在启动EC2时，我可以在user_data字段中包含带参数的脚本文件吗？

Question

启动EC2时，我可以在user_data字段中包含带参数的脚本文件吗？ 如：     user_data =＆＃34; $ {file（＆＃34; install_software.sh＆＃34;），user_name pass_word}＆＃34;

此外，我可以在user_data字段中包含多个脚本文件吗？如：     user_data =＆＃34; $ {file（＆＃34; install_software1.sh＆＃34;，＆＃34; install_software2.sh＆＃34;）}＆＃34;

我还没有看到它们的任何例子，所以我不知道格式是什么。如果我不能使用user_data这样做，该怎么做？我应该使用remote-exec还是......别的？

Answer 1

您要使用的是template_file

data "template_file" "user_data" {
  template = "${file("script1.sh.tpl")}"

  vars {
    var1 = "foo"
    var2 = "bar"
  }
}

如果要在user_data中使用多个脚本，则需要遵循cloud-init多部分格式并将其放在一个或多个文件* .tpl中，然后使用terraform标准插值或内联模板进行组合。
