Chef - 如何在脚本中使用属性列表 [英] Chef - how to use a list of attributes in a script

问题描述

我是 Chef 的新手，我想执行一个脚本来在我的系统中添加用户.我在厨师中有一本名为 usersinto 和属性的食谱:

I'm newbie in Chef and I want to execute a script to add users in my system. I have a cookbook in chef called usersinto and attributes:

node.default["usersinto"]["users"] = [ " user1 user2 user3 .... userN " ]

在配方中被调用:

bash "launch-add" do
    code <<-EOH
        sh /home/user/addusers.sh "#{node["usersinto"]["users"]}"
    EOH
end

我会尝试很多东西，如果我在属性中使用["，脚本会捕获["作为参数 $1，如果我不使用[]"，脚本只会捕获第一个用户.我怎么能这样做??

I'll try a lot of things, if I use in attributes "[", the script catches "[" as argument $1, if I don't use "[ ]" the script only catches the first user. How could I do this??

提前致谢:)

推荐答案

您的脚本似乎接受了一个参数.我无法判断该参数是单个用户还是单个用户字符串.如果它只接受一个用户，您需要将您的 node["usersinto"]["users"] 属性设为一个数组(这看起来无论如何都应该是一个数组).

It seems your script accepts one argument. What I can't tell if that argument is a single user in or a single string of users. If it only accepts one user, you'd need to make your node["usersinto"]["users"] attribute an array (this looks like it should be an array in any case).

node.default["usersinto"]["users"] = %w{user1 user2 user3} 

一旦你有了你的数组，迭代它，为每个用户执行 bash 脚本.

Once you have your array, iterate over it executing the bash script for each user.

node["usersinto"]["users"].each do |user|
    bash "launch-add" do 
       code <<-EOH 
         sh /home/user/addusers.sh #{user}
       EOH 
    end
end

如果您的脚本接受多个参数(每个参数是不同的用户)

In the case that your script accepts multiple arguments (each argument being a different user)

bash "launch-add" do 
   code <<-EOH 
     sh /home/user/addusers.sh #{node['usersinto']['users'].join(' ')}
   EOH 
end
