如何在不包含脚本内联的情况下使用user_data填充OpenStack中的热模板? [英] How can I populate a heat template in OpenStack with `user_data` without including the script inline?

问题描述

即我希望模板看起来像这样:

I.e. I want my template to look something like:

...
resources:
  server1:
    type: OS::Nova::Server
    properties:
      name: Server1
      image: { get_param: image }
      flavor: { get_param: flavor }
      user_data: ?????
...

并且我希望将user_data的内容存储在一个单独的文件中.

and I want the contents of user_data to be stored in a separate file.

我该怎么做?

推荐答案

我相信这就是 get_file 用于.来自文档:

I believe that's what get_file is for. From the doc:

下面的示例演示了get_file的用法以及相对和 绝对网址.

The example below demonstrates get_file usage with both relative and absolute URLs.

resources:
  my_instance:
    type: OS::Nova::Server
    properties:
      # general properties ...
      user_data:
        get_file: my_instance_user_data.sh
  my_other_instance:
    type: OS::Nova::Server
    properties:
      # general properties ...
      user_data:
        get_file: http://example.com/my_other_instance_user_data.sh

如果此模板是从本地文件启动的，则会导致 文件字典，包含带有键的条目 file:///path/to/my_instance_user_data.sh和 http://example.com/my_other_instance_user_data.sh .

If this template was launched from a local file this would result in a files dictionary containing entries with keys file:///path/to/my_instance_user_data.sh and http://example.com/my_other_instance_user_data.sh.
