I have a simple DSC Config file that contains a credential and string input parameter. I want this DSC configuration deployed with a VM deployed in an ARM template but am missing the concept of how to pass these two parameters securely. How do I accomplish this?

I was receiving the same error but, after some shenanigans, it is working for me. The important part is the settings/Properties/SqlAgentCred/password
reference to protectedSettings/Items/AgentPassword
. Below is the properties node under my Powershell.DSC extension resource in my template.
"properties": {
"publisher": "Microsoft.Powershell",
"type": "DSC",
"typeHandlerVersion": "2.17",
"autoUpgradeMinorVersion": false,
"settings": {
"ModulesUrl": "https://blobstore.blob.core.windows.net/windows-powershell-dsc/DBServer.ps1.zip",
"ConfigurationFunction": "DBServer.ps1\\DBServer",
"Properties": {
"SqlAgentCred": {
"userName": "user@domain.com",
"password": "PrivateSettingsRef:AgentPassword"
}
},
"WmfVersion": "latest",
"Privacy": {
"DataCollection": "Disable"
}
},
"protectedSettings": {
"Items": {
"AgentPassword": "Pa$$word"
},
"DataBlobUri": ""
}
}

You will specify protected settings under protectedsettings section. Anything under ProtectedSettings are sent encrypted. Check https://blogs.msdn.microsoft.com/powershell/2016/02/26/arm-dsc-extension-settings/ for details.

This is a good reference and a start but not entirely clear. My DSC configuration has required PSCredential object. If I simply add a "Credential" object in the ProtectedSettings.configurationArguments property by adding a userName and password property the DSC configuration fails because it cannot find the Credential parameter. – ChiliYago Sep 30 '16 at 21:10

Hello, it sounds like what you are doing should work. Would you post the value of protectedSettings you used in your template, and the error reported by the extension? Thanks! – Norberto Arrieta Oct 03 '16 at 21:38

@NorbertoArrieta I'm having the same problem. Here is my protectedSettings section:`"protectedSettings": { "configurationArguments": { "SqlAgentCred": { "userName": "user@domain.com", "password": "password" } }, "DataBlobUri": "" }` – sirdank Dec 22 '16 at 15:39

@sirdank They look OK. What is the error reported by the extension? thanks – Norberto Arrieta Dec 23 '16 at 23:37

@NorbertoArrieta Sorry, I'm unable to find the original error. I did get it working though. See my answer to this question. – sirdank Dec 27 '16 at 13:10
