[英]Ruby operations on template variables - Chef
I have written following template in my chef cookbook recipe 我已经在我的厨师食谱食谱中编写了以下模板
template '/etc/app.conf' do
variables({
my_id: Chef::HTTP.new(https://example.com).get('/',{header})
})
end
And my erb file is 我的erb文件是
Output is : <%= @my_id %>
I actually want to perform some ruby operations(mainly filter out and count the components of my_id) and then pass those values(count of each component) back to the template and use it further. 我实际上想执行一些ruby操作(主要是过滤出并计数my_id的组件),然后将这些值(每个组件的数量)传递回模板并进一步使用它。 What should be erb configuration or anything thats need to be added in template block?
erb配置应该是什么,或者需要在模板块中添加什么?
(Here, my_id actually has the subnets and I want to get those the count of those subnets and its values so that I can use it further to perform another http request and get the nodes in each of the subnet). (在这里,my_id实际上具有子网,我想获取那些子网的数量及其值,以便可以进一步使用它执行另一个http请求并获取每个子网中的节点)。
The thing you pasted from (hopefully you were summarizing since you missed a bunch of quotes in there) was only a quick tip. 您粘贴的内容(希望您进行了总结,因为您错过了其中的一堆引号)只是一个快速提示。 To get JSON data you want to use
Chef::HTTP::SimpleJSON
, the will do the parsing for you and whatnot. 要获取JSON数据,您想使用
Chef::HTTP::SimpleJSON
,它将为您进行解析, Chef::HTTP::SimpleJSON
进行其他操作。
variables data: Chef::HTTP::SimpleJSON.new('https://whatever.com/').get('/foo')
