Chef 10：如何使用remote_file或类似方法从Windows共享中获取文件？ [英] Chef 10: How to use remote_file or similar to get a file from a Windows share?

问题描述

我正在尝试使用 remote_file 在Windows共享上缓存大型软件包的本地副本。如何完成？

I'm trying to use remote_file to cache a local copy of a large package on a Windows share. How is this done?

我无法使其与基于驱动器字母的路径，基于UNC的路径或文件： URL。

I can't get it to work with a drive-letter-based path, a UNC-based path, or a file: URL.

推荐答案

我制定了一个技巧，我认为它很简洁。我创建了以下定义（并将其放在 definitions / default.rb 中）：

I worked out a trick that I think is pretty neat. I created the following definition (and put it in definitions/default.rb):

define :file_from_network, :action => :create do
   myPath = (params[:path] || params[:name])
   mySource = params[:source]

   if File.exist?(mySource)
      file myPath do
         action params[:action]
         content File.open(mySource) {|io| io.read}
      end
   else
      Chef::Log.error("File #{mySource} not found!")
   end
end

定义的工作方式与资源不同，但这很容易实现，并且可以满足我的需要。当然，通过内存读取无法对大文件进行操作，但是它允许Chef在触发对文件资源的操作之前检查内容是否不同。

Definitions do not work quite the same way resources do, but this was easy to implement and does what I need it to do. The in-memory read makes it impractical for huge files, of course, but it allows Chef to check that the content is different before triggering an action on the file resource.
