问题描述

首先，我很抱歉提出这样一个愚蠢的问题。但是我问的原因是因为我很难找到答案。我尝试搜索Chef的文档，但没有找到明确的解释。

First off, I apologize for asking such a dumb question. But the reason I ask is because I'm having a hard time finding an answer. I've tried searching Chef's docs, but I have not found a clear explanation.

那么 Chef :: Config [：file_cache_path]到底能做什么？ 提供？我读到最好用它而不是对文件路径进行编码。但是它的计算结果是什么？

So what exactly doesChef::Config[:file_cache_path] provide? I've read that its better to use this instead of harding coding a filepath. But what does it evaluate to?

在此特定代码段中

newrelic_agent = Chef::Config[:file_cache_path] + '/rewrelic_nginx_agent.tar.gz'


remote_file newrelic_agent do
  source 'http://nginx.com/download/newrelic/newrelic_nginx_agent.tar.gz'
  mode "0744"
end

推荐答案

具体值因平台和安装方法而异，但该配置值默认为您可以编写的位置临时文件。通常，它类似于 / var / chef / cache 。
用于缓存食谱和其中的文件，但正如您指出的，您还可以从自己的代码中使用它。

The specific value varies by platform and method of install, but that config value defaults to somewhere you can write out temp files. Generally it will be something like /var/chef/cache. This is used for caching cookbooks and files in them, but as you noted you can also use it from your own code for the same kind of thing.
