如何编写模板以在zoo.cfg中自动编写“server.x = hostname：Quorom_Port：Election_Port”

Question

我想＆＃34; server.x =主机名：Quorom_Port：Election_Port＆＃34;要使用基于attributes / default.rb文件中声明的数字主机的模板写入zoo.cfg的值

default['zookeeper']['servers'] = ["hostname1", "hostname2", "hostname3"]
default['zookeeper']['follower_port'] = 2888
default['zookeeper']['election_port'] = 3888

对于上述属性，应使用模板在zoo.cfg文件中自动写入以下值：

server.1= hostname1:2888:3888
server.2= hostname2:2888:3888
server.3= hostname3:2888:3888

请告诉我怎么做？

Answer 1

<%- if node['zookeeper']['servers'] %>
    <%- node['zookeeper']['servers'].each_with_index do |host, idx| %>
        server.<%= idx+1 %>=<%= host %>:<%= node['zookeeper']['follower_port']%>:<%= node['zookeeper']['election_port']%>
    <%- end %>
<%- end %>
