How do I use ARM 'outputs' values another release task?

Question

I have an ARM template that has and outputs section like the following:

"outputs": {

    "sqlServerFqdn": {

        "type": "string",

        "value": "[reference(concat('Microsoft.Sql/servers/', variables('sqlserverName'))).fullyQualifiedDomainName]"

    },

    "primaryConnectionString": {

        "type": "string",

        "value": "[concat('Data Source=tcp:', reference(concat('Microsoft.Sql/servers/', variables('sqlserverName'))).fullyQualifiedDomainName, ',1433;Initial Catalog=', variables('databaseName'), ';User Id=', parameters('administratorLogin'), '@', variables('sqlserverName'), ';Password=', parameters('administratorLoginPassword'), ';')]"

    },

    "envResourceGroup": {

        "type": "string",

        "value": "[parameters('hostingPlanName')]"

    }

}

I have an Azure Resource Group Deployment task that uses the template. I then want to use the variable $(sqlServerFqdn) in the next task for configuration. The variable doesn't seem to just populate and I cannot find anywhere that tells me how to use 'outputs' values on release.

What do I need to do to get the variable to populate for use in configuring tasks after this ARM template runs? An example would be in the parameters to a PowerShell script task or another ARM template.

Simply add this to your PowerShell script following your ARM Template:

param(

 [string]  $resourceGroupName

)

$lastDeployment = Get-AzureRmResourceGroupDeployment -ResourceGroupName $resourceGroupName | Sort Timestamp -Descending | Select -First 1 

if(!$lastDeployment) {

    throw "Deployment could not be found for Resource Group '$resourceGroupName'."

}

if(!$lastDeployment.Outputs) {

    throw "No output parameters could be found for the last deployment of Resource Group '$resourceGroupName'."

}

foreach ($key in $lastDeployment.Outputs.Keys){

    $type = $lastDeployment.Outputs.Item($key).Type

    $value = $lastDeployment.Outputs.Item($key).Value

    if ($type -eq "SecureString") {

        Write-Host "##vso[task.setvariable variable=$key;issecret=true]$value" 

    }

    else {

        Write-Host "##vso[task.setvariable variable=$key;]$value" 

    }

} 

Note that the environmental variables won't be available in the context of this script, but will in subsequent tasks.
