Use PowerShell module in ARM deployment script

Time：05-03

I have an ARM template in which I wish to execute a powershell script. In this question it is hinted that it should be possible to install powershell modules in the script.

I am unable to import the module I want to use.

This is the ARM template deploymentScript:

        {
        "type": "Microsoft.Resources/deploymentScripts",
        "apiVersion": "2020-10-01",

        "location": "[resourceGroup().location]",
        "dependsOn": [
            "[resourceId('Microsoft.Sql/servers/databases', parameters('serverName'), parameters('databaseSettings').databases[copyIndex()].name)]",
            "[resourceId('Microsoft.Sql/servers', parameters('serverName'))]"
        ],
        "kind": "AzurePowerShell",
        "properties": {
          "azPowerShellVersion": "7.4",
          "timeout": "PT30M",
          "arguments": "[format(' -serverName {0} -databaseName {1} -userName {2} -password {3}  -appId {4} ', parameters('serverName'), parameters('databaseSettings').databases[copyIndex()].name, parameters('adminUsername'), parameters('adminPassword'), parameters('databaseSettings').databases[copyIndex()].appId)]",
          "scriptContent": "
            param(
              [string] [Parameter(Mandatory=$true)] $serverName,  
              [string] [Parameter(Mandatory=$true)] $databaseName,
              [string] [Parameter(Mandatory=$true)] $userName,
              [string] [Parameter(Mandatory=$true)] $password,
              [string] [Parameter(Mandatory=$true)] $appId
            )

            $ErrorActionPreference = 'Stop'
            $DeploymentScriptOutputs = @{}
            
            Install-Module -Name SqlServer
            Import-Module -Name SqlServer

            Invoke-Sqlcmd -ServerInstance $serverName
                          -database $databaseName
                          -username $userName
                          -password $password
                          -query 'CREATE USER $appId FROM EXTERNAL PROVIDER'
          ",
          "cleanupPreference": "OnSuccess",
          "retentionInterval": "P1D"
        },
        "copy": {
            "name": "dbgeobackupcopy",
            "count": "[length(parameters('databaseSettings').databases)]"
        }
    }

This is the error:

If I remove the import statement and simply use the install I get an error that indicates the command is not recognised.

How can I use the sql module in the deployment script?

CodePudding user response：

Try this for your script resource - note some of the params are different than your original (no copy loop). Inline PS scripts can be challenging to debug, esp with args that have quotes, spaces, dollar signs (in pwsh).

Notable differences from yours:

  • the serverName needs to be fully qualified
  • line breaks in the invoke-sqlcmd need to have a backtick (I believe)
  • quote the password and query string
  • using env vars instead of args (to save more quoting headaches)
  • use -Force to install the module (unless the gallery is trusted)

and of course make sure the firewall rules all connections to sql

Aside, it would be faster to loop inside the script if passing the params was reasonable.
