Authenticate Azure Blob Storage Account in cloud using a runbook - azure-powershell

Question

In AZURE ANALYSIS SERVICES Tabular model (with compatibility level 1400) I imported a Blob storage account as a Data Source. It's Authentication Kind is Key kind of authentication. The key is a Static Key.
But while refreshing the Tabular using a Runbook in Automation Account (Cloud PowerShell) is there a way to pass the key/credentials so that it could authenticate?
Otherwise the PowerShell fails with below message
The given credential is missing a required property. Data source kind: AzureBlobs. Authentication kind: Key. Property name: Key. The exception was raised by the IDbConnection interface.
Here is the Source definition copied from Model.bim file:
{
"createOrReplace": {
"object": {
"database": "azureanalysisservicesdatabase",
"dataSource": "OMSLogs"
},
"dataSource": {
"type": "structured",
"name": "OMSLogs",
"connectionDetails": {
"protocol": "azure-blobs",
"address": {
"account": "storage",
"domain": "blob.core.windows.net"
},
"authentication": null,
"query": null
},
"credential": {
"AuthenticationKind": "Key",
"kind": "AzureBlobs",
"path": "https://storage.blob.core.windows.net/",
"PrivacySetting": "Organizational"
}
}
}
}
this is the code I ran in PowerShell to process the Database:
Invoke-ProcessASDatabase -databasename $DatabaseName -server $AnalysisServerName -RefreshType "Full" -Credential $SPCredential

Answer 1

Okay I also hit a similar issue and found the solution, add "Key" to the "credential" object:
"credential": {
"AuthenticationKind": "Key",
"kind": "AzureBlobs",
"path": "https://storage.blob.core.windows.net/",
"PrivacySetting": "Organizational",
"Key": "<StorageAccountKey>"
}
This isn't well documented by Microsoft, but this worked for me
Update with PowerShell sample:
Get-ChildItem -Filter "drop" -Recurse -Path $sourcePath -Directory |
Get-ChildItem -recurse -filter *.asdatabase -file | ForEach-Object {
$filename = $_.fullname
$generatedFile = $buildPath + $_.BaseName + ".xmla"
"Processing $filename"
& $deploymentWizard $filename /o:$generatedFile
# Have to add Blob Key now, as Deployment Wizard doesn't like
# adding the Key (bug maybe? Or DeloyWizard isn't up to date)
$file = Get-Content $generatedFile -Raw | ConvertFrom-Json
$file.createOrReplace.database.model.dataSources | ForEach-Object {
# Add Blob Key to credential object
if ($_.name.StartsWith("AzureBlobs/")) {
$_.credential | Add-Member -Name "Key" -Value $storageKey -MemberType NoteProperty -Force
}
}
$file = $file | ConvertTo-Json -Depth 32
$file | Set-Content -Path $generatedFile -Encoding utf8
}
