Ruby(Chef)无法将哈希数组传递到Chef资源中

Question

我正在尝试创建一个将远程桌面服务部署到Windows服务器的配方，除了我创建的应用程序部署资源外，一切都按预期工作-这是一个简单的资源，但我在将要部署的应用程序传递为哈希数组时遇到了很多问题。

attributes\default.rb

default['app']['app_options'] = [{
app1:{
connection_broker: 'serv-01',
options: {
collectionname: 'Terminal Services', alias: 'Acrobat', displayname: 'Adobe Acrobat', filepath: 'C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe', filevirtualpath: 'C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe', ommandlinesetting: 'DoNotAllow', iconindex: 0, iconpath: '\\serv-01\C$\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe', usergroups: ['domain\group'], showinwebaccess: 1
}
},
app2:{
connection_broker: 'serv-01',
options: {
collectionname: 'Terminal Services', alias: 'Accounts', displayname: 'Accounts', foldername: 'Accounts', filepath: 'D:\Accounts\Accounts.bat', filevirtualpath: 'D:\Accounts\Accounts.bat', commandlinesetting: 'DoNotAllow', iconindex: 0, iconpath: 'C:\Windows\System32\cmd.exe', usergroups: ['domain\group'], showinwebaccess: 1
}
}
}]

配方\remote_desktop.rb

rdapps = node.read('app', 'app_options') || []
rdapps.each do |app|
remote_desktop_apps app['options']['alias'] do
action :create
connection_broker app['connection_broker']
app_options app['options']
end
end

resources\remote_desktop_apps.rb

resource_name :remote_desktop_apps
property :connection_broker, String,
desired_state: false
property :app_options, [String, Hash, Array],
desired_state: false
action :create do
app_options.each do |k,v|
script << "New-RDRemoteApp -ConnectionBroker "#{connection_broker}" {-#{k.to_s.capitalize} #{v}}.join(' ')}"
end
end

当在Test Kitchen中运行配方时，我得到以下错误：

================================================================================
Recipe Compile Error in C:/Users/ADMINI~1/AppData/Local/Temp/kitchen/cache/cookbooks/windows_/recipes/remote_desktop.rb

编辑

感谢@seshadri_c帮助我克服了第一道障碍，我遇到了另一个似乎与属性有关的问题。

这是厨房收敛的输出

================================================================================

end

然后在运行结束时出现以下消息：

Answer 1

此错误的原因是哈希数组具有不同的键app1和app2。因此，每次我们在rdapps上迭代时，我们都会得到一个不同的密钥。这样我们就不能得到像app['options']['alias']这样的子元素。

因此，您可以将属性调整为类似以下内容：

default['app']['app_options'] = [
{
connection_broker: 'serv-01',
options: {
collectionname: 'Terminal Services',
alias: 'Acrobat',
displayname: 'Adobe Acrobat',
filepath: 'C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe',
filevirtualpath: 'C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe',
ommandlinesetting: 'DoNotAllow',
iconindex: 0,
iconpath: '\\serv-01\C$\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe',
usergroups: ['domain\group'],
showinwebaccess: 1
}
},
{
connection_broker: 'serv-01',
options: {
collectionname: 'Terminal Services',
alias: 'Accounts',
displayname: 'Accounts',
foldername: 'Accounts',
filepath: 'D:\Accounts\Accounts.bat',
filevirtualpath: 'D:\Accounts\Accounts.bat',
commandlinesetting: 'DoNotAllow',
iconindex: 0,
iconpath: 'C:\Windows\System32\cmd.exe',
usergroups: ['domain\group'],
showinwebaccess: 1
}
}
]

然后我们可以像预期的那样工作：

rdapps = node.read('app', 'app_options') || []
rdapps.each do |app|
remote_desktop_apps app['options']['alias'] do
action :create
connection_broker app['connection_broker']
app_options app['options']
end
end
