推荐答案
。通过小的修改,如果我理解正确的问题,便可以这样解决您的问题:
The answer to your question is pretty mich given in How can I put the output of a Chef 'execute resource' into a variable. With tiny modification, if I understand the question right, your problem can be solved like this:
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
替换命令的内容
使用您要运行的命令,并使用 my_attribute
使用要设置的属性。
Replace the content of command
with the command that you want to run and my_attribute
with the attribute that you want to set.
