Templates 对单个木偶清单中的不同文件使用单个erb模板

我喜欢使用单个erb模板创建不同的文件。这是我的雇员再培训局

# managed by puppet
# changes will be overwritten
#
<% if (@tanuki_ssl != nil) -%>
# config include
# ssl section for trust and key stores
#
<% unless @tanuki_ssl['truststore_path'].nil? -%>
wrapper.java.additional.940=-Djavax.net.ssl.trustStore=<%= @tanuki_ssl['truststore_path'] %>
<% end -%>
<% unless @tanuki_ssl['truststore_pass'].nil? -%>
wrapper.java.additional.941=-Djavax.net.ssl.trustStorePassword=<%= @tanuki_ssl['truststore_pass'] %>
<% end -%>
<% end -%>
<% if (@tanuki_proxy != nil) -%>
# config include
# proxy section
#
wrapper.java.additional.951=-Dhttp.proxySet=true
wrapper.java.additional.952=-Dhttp.proxyHost=<%= @tanuki_proxy['host'] %>
wrapper.java.additional.953=-Dhttp.proxyPort=<%= @tanuki_proxy['port'] %>
wrapper.java.additional.954=-Dhttp.nonProxyHosts=<%= @tanuki_proxy['exceptions'].join('|') %>|<%= @ipaddress %>|<%= @hostname %>
wrapper.java.additional.955=-Dhttps.proxySet=true
wrapper.java.additional.956=-Dhttps.proxyHost=<%= @tanuki_proxy['host'] %>
wrapper.java.additional.957=-Dhttps.proxyPort=<%= @tanuki_proxy['port'] %>
wrapper.java.additional.958=-Dhttps.nonProxyHosts=<%= @tanuki_proxy['exceptions'].join('|') %>|<%= @ipaddress %>|<%= @hostname %>
<% end -%>

我现在运行puppet，得到一个包含预期内容的文件940-ssl.incl。仅解释第一个if部分

但是文件950-proxy.inc也有ssl部分

那么，如何只传递每个文件所需的变量呢

干杯

无法将不同的变量传递给ERB

template（）

函数，因此我认为您需要：

使用with而不是ERB，这样可以在调用模板时将不同的局部变量传递到模板中

使用不同的模板或不同的作用域。在同一范围内呈现同一模板通常应该呈现相同的结果，这正是您试图解决的问题

我找到了另一种适合我的方法。我创建了一个定义：

define tools::app::tanuki::include (
  Hash $property_hash      = {},
  String $include_template = 'tools/app/tanuki/wrapper.inc.erb',
  String $include_filename = $title,
){
  if $property_hash != {} {
    file { $include_filename:
      content  => template($include_template),
    }
  }
}

在我的木偶清单中，我修改了代码如下：

if $tanuki_hash['ssl_enabled'] {

  $include_ssl = { type => 'ssl' }
  $tanuki_ssl_hash = merge($tanuki_hash['ssl'],$include_ssl)

  tools::app::tanuki::include { "${tanuki_path}/${dirname}/conf/940-ssl.inc":
    property_hash    => $tanuki_ssl_hash,
  }
}

if $tanuki_hash['proxy_enabled'] {

  $include_proxy = { type => 'proxy' }

  if $tanuki_hash['override_system_proxy'] {
    $tanuki_proxy=$tanuki_hash['proxy']
    $tanuki_proxy_hash = merge($tanuki_hash['proxy'],$include_proxy)
  } else {
    $tanunki_proxy=$proxy_hash
    $tanuki_proxy_hash = merge($proxy_hash,$include_proxy)
  }

  tools::app::tanuki::include { "${tanuki_path}/${dirname}/conf/950-proxy.inc":
    property_hash    => $tanuki_proxy_hash,
  }
}

所以我可以在erb上定义不同的包含，我稍微修改了一下
