如何传递的UserData与CloudFormation一个魔豆实例 [英] How do I pass UserData to a Beanstalk instance with CloudFormation

问题描述

我需要的应用服务器，这是豆茎情况下，要做到在启动时的一些动作，我想运行传递到该实例的属性的UserData这是提供给普通的EC2实例一bash脚本的。

I need the application server, which is beanstalk instances, to do some actions upon startup and I thought of running a bash script passed to the instance with the UserData property which is available to regular EC2 instances.

我已经发现了几个例子CloudFormation模板，这是否与普通EC2实例，但青苗没有例子。我试图把它添加到性能领域的应用：

I've found several example CloudFormation templates which does this with regular EC2 instances, but no example with Beanstalk. I've tried to add this to the properties field for the application:

"MyApp" : {
  "Type" : "AWS::ElasticBeanstalk::Application",
  "Properties" : {
    "Description" : "MyApp description",
    "ApplicationVersions" : [{
      ...
    }],
    "UserData" : {
      "Fn::Base64" : { "Fn::Join" : ["", [
        "#!/bin/bash\n",
        "touch /tmp/userdata_sucess\n"
      ]]
    }},
    ...

我也尝试添加到环境的一部分：

I also tried to add to the environment part:

"MyAppEnv" : {
  "Type" : "AWS::ElasticBeanstalk::Environment",
  "Properties" : {
    "ApplicationName" : { "Ref" : "MyApp" },
    "Description" :  "MyApp environment description",
    "UserData" : {
      "Fn::Base64" : { "Fn::Join" : ["", [
        "#!/bin/bash\n",
        "touch /tmp/userdata_sucess\n"
      ]]
    }},
    "TemplateName" : "MyAppConfiguration",
    "VersionLabel" : "First Cloud version"
  }
},

在这两种情况下试图创建堆栈若这导致了失败。有谁知道是否有可能通过的UserData使用CloudFormation一个魔豆实例。如果是这样的 - 你可以提供一个例子

In both cases this resulted in failure when trying to create the stack. Does anyone know if it is possible to pass UserData to a Beanstalk instance using CloudFormation. If so - can you provide an example.

推荐答案

如果你想拥有所有的魔豆提供了优势 - 好像没有修补这亚马逊为你做操作系统 - 这是不可能的。一种选择是，你有必要的脚本来创建一个自定义的AMI，但你必须用你自己的安全补丁管理操作系统。了解更多这里。

If you want to have all the advantages that Beanstalk offers - like not having to patch the OS which Amazon does for you - this isn't possible. One option is to create a custom AMI where you include the needed scripts, but then you must manage the OS yourself with security patches. Read more here.
