所以这可能有点令人困惑,但请耐心等待.简而言之,我希望使用某个键值循环所有属性,然后在值不为空时将它们插入模板中.这是我的代码:

属性:

# === Default file Configurations
#
default['elasticsearch']['default']['ES_USER']              = ''
default['elasticsearch']['default']['ES_GROUP']             = ''
default['elasticsearch']['default']['ES_HEAP_SIZE']         = ''
default['elasticsearch']['default']['MAX_OPEN_FILES']       = ''
default['elasticsearch']['default']['MAX_LOCKED_MEMORY']    = 'unlimited'
default['elasticsearch']['default']['MAX_MAP_COUNT']        = ''
default['elasticsearch']['default']['LOG_DIR']              = '/var/log/elasticsearch'
default['elasticsearch']['default']['DATA_DIR']             = '/var/lib/elasticsearch'
default['elasticsearch']['default']['WORK_DIR']             = '/tmp/elasticsearch'
default['elasticsearch']['default']['CONF_DIR']             = '/etc/elasticsearch'
default['elasticsearch']['default']['CONF_FILE']            = '/etc/elasticsearch/elasticsearch.yml'
default['elasticsearch']['default']['RESTART_ON_UPGRADE']   = ''

模板:

<% node['elasticsearch']['default'].each do |host| -%>
    <% if node.elasticsearch.default.host not nil -%>
        <%= host %>=<%= node.elasticsearch.default.host %>
<% end %>

输出(希望):

MAX_LOCKED_MEMORY=unlimited
LOG_DIR=/var/log/elasticsearch
DATA_DIR=/var/lib/elasticsearch
WORK_DIR=/tmp/elasticsearch
CONF_DIR=/etc/elasticsearch
CONF_FILE=/etc/elasticsearch/elasticsearch.yml

我的红宝石不是最好的,因为我刚刚开始使用所有这些东西,但我找不到这种情况的任何例子.任何帮助都会很棒,谢谢.
