无法将哈希从 hiera 解析到 erb 模板中

Question

我有一个木偶清单，看起来像这样：

$webapp_list = lookup('webapps', Hash, 'hash')
$webapp_list.each | $app_name, $app_info| {
$app_port = $app_info[port]
$app_description = $app_info[description]
$app_settings = [ $app_info[settings] ]

和 hiera 代码：

webapps:
webapp-template:
port: 5001
description: "Webapp Description"
live: false
settings:
FLASK_APP: appname.py
MAIL_USERNAME: [e-mail]
MAIL_PASSWORD: <extra strong password>

我正在使用如下所示的 erb 模板：

<% @app_settings.each do |settingKey, settingValue| -%>
export <%= settingKey -%>='<%= settingValue -%>'
<% end %>

尝试生成如下所示的文件：

export FLASK_APP=appname.py
export MAIL_USERNAME=[e-mail]
export MAIL_PASSWORD=<extra strong password>

我已经尝试了各种不同的方法(这只是最新的(，这些方法会导致 puppet 出错：

Info: Using configured environment 'special'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Failed to parse template webapps/settings.conf.erb:

at /etc/puppet/code/modules/webapps/manifests/init.pp:40:18 on node web.home
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

或生成如下所示的文件：

export {"FLASK_APP"=>"appname.py", "MAIL_USERNAME"=>"[e-mail]", "MAIL_PASSWORD"=>"<extra strong password>"}=''

我知道答案在某种程度上与我如何处理数组和哈希有关，并且解决方案正盯着我的脸，但我目前对下一步行动一无所知。

Answer 1

我已经找到了解决方案。这主要是因为我的yaml文件我有其他没有"设置"部分的网络应用程序，导致它倒塌。我的最终代码可以在下面看到。

希拉：

webapps:
webapp-template:
port: 5001
description: "Webapp Description"
live: false
settings:
FLASK_APP: appname.py
MAIL_USERNAME: [e-mail]
MAIL_PASSWORD: <extra strong password>

傀儡清单：

$webapp_list = lookup('webapps', Hash, 'hash')
$webapp_list.each | $app_name, $app_info| {
$app_port = $app_info[port]
$app_description = $app_info[description]
$app_settings = $app_info[settings]

Settings.conf.erb：

<% @app_settings.each do |key,value| -%>
export <%= key %>='<%= value %>'
<% end -%>
