如何将linux命令输出到chef属性

Question

我想将命令输出转换为chef属性.有人可以帮助我如何在执行资源或bash资源中设置它.

ruby_block "something" do
    block do
        #tricky way to load this Chef::Mixin::ShellOut utilities
        Chef::Resource::RubyBlock.send(:include, Chef::Mixin::ShellOut)      
        command = 'cat #{fileName}'
        command_out = shell_out(command)
        node.set['my_attribute'] = command_out.stdout
    end
    action :create
end

如何在上面的代码中使用属性..

Answer 1

您的问题的答案非常明确我如何将Chef'执行资源'的输出放入变量中.通过微小的修改,如果我理解正确的问题,您的问题可以像这样解决:

ruby_block "something" do
    block do
        #tricky way to load this Chef::Mixin::ShellOut utilities
        Chef::Resource::RubyBlock.send(:include, Chef::Mixin::ShellOut)      
        command = 'cat /etc/hostname'
        command_out = shell_out(command)
        node.set['my_attribute'] = command_out.stdout
    end
    action :create
end

使用command要运行的命令和my_attribute要设置的属性替换内容.
