Add a Azure WebApp to an Existing VPN using a Point-to-Site connection (RM Powershell)

问题


I have hunted around for an answer to this, but I am not having much luck. All the articles I can find are either setting up a Point-to-Site or are instructions for classic Azure, not Azure 2.0 (Resource Group)

Currently, we are dialing up a whole new resource group everytime we do a new built. This consists of Web apps and SQL DBs. When we have a new build we start up the new and del the old resource group. Simple. To minimize the start-up time we have a static resource group that isn't deleted that houses the VPN connection to our on Prem resources.

The problem I'm having is when I add the new websites using AzureRM Powershell cmd's to the Point-to-site it says it's successful. The Azure Portal says its good but it does let me communicate. If I remove and add it from one of the 8 WebApps they all start working.

I am out of ideas. Any help would be greatly appreciated.

Azure VPN

Below is the function I have put togeather from what I can find out there.

function AddExistingVnet{
param(
    [string] $subscriptionId,
    [string] $resourceGroupName,
    [string] $webAppName

)

$Vnet = Get-AzureRmVirtualNetwork | Where-Object {$_.ResourceGroupName -like "*Static*"}

IF($Vnet.Name.count -gt 1) {write-host 'Two or networks have been returned. Unable to continue ' return}

    $gatewaySubnet = $vnet.Subnets | Where-Object { $_.Name -eq "GatewaySubnet" }
    $vnetName = $vnet.Name
    $uriParts = $gatewaySubnet.IpConfigurations[0].Id.Split('/')
    $gatewayResourceGroup = $uriParts[4]
    $gatewayName = $uriParts[8]
    $gateway = Get-AzureRmVirtualNetworkGateway -ResourceGroupName $vnet.ResourceGroupName -Name $gatewayName

    Write-Host "Creating App association to VNET"
    $propertiesObject = @{
     "vnetResourceId" = "/subscriptions/$($subscriptionId)/resourceGroups/$($vnet.ResourceGroupName)/providers/Microsoft.Network/virtualNetworks/$($vnetName)"
    }

    $virtualNetwork = New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -Force

# Now finish joining by getting the VPN package and giving it to the App
Write-Host "Retrieving VPN Package and supplying to App"
$packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64

# Put the VPN client configuration package onto the App
$PropertiesObject = @{
"vnetName" = $vnet.Name; "vpnPackageUri" = $packageUri
}

New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)/primary" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections/gateways" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -WarningAction silentlyContinue -Force 

}

So after 2 weeks of going back and forth with Microsoft (had a really good guy Charles) we managed to find the problem.

When requesting

$packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64

It was giving me an output of:

"https://mdsbrketwprodsn1prod.blob.core.windows.net/cmakexe/xxx~xxx/amd64/xxxx~xxxx&sp=r&fileExtension=.exe"

For some reason (that Microsoft could explain) why it kept adding in " to the beginning and end of the variable.

I find it odd that it lets the script work with " and allows the WebApps to join to the VPN.

Any why here is the fix which basicly removes the " from the begining and end of $packageUri :

$packageUri = $packageUri.ToString(); 
$packageUri = $packageUri.Substring(1, $packageUri.Length-2);

So hope that helps someone else out there who is banging there head agaist the same problem.

Here is the complete function if any one is intrested:

function AddExistingVnet{
    param(
        [string] $subscriptionId,
        [string] $resourceGroupName,
        [string] $webAppName

    )


$Vnet = Get-AzureRmVirtualNetwork | Where-Object {$_.ResourceGroupName -like "*Static*"}


IF($Vnet.Name.count -gt 1) {write-host 'Two or networks have been returned. Unable to continue ' return}

        $gatewaySubnet = $vnet.Subnets | Where-Object { $_.Name -eq "GatewaySubnet" }
        $vnetName = $vnet.Name
        $uriParts = $gatewaySubnet.IpConfigurations[0].Id.Split('/')
        $gatewayResourceGroup = $uriParts[4]
        $gatewayName = $uriParts[8]
        $gateway = Get-AzureRmVirtualNetworkGateway -ResourceGroupName $vnet.ResourceGroupName -Name $gatewayName

        $webApp = Get-AzureRmResource -ResourceName $webAppName -ResourceType "Microsoft.Web/sites" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName
        $location = $webApp.Location

        Write-Host "Creating App association to VNET"
        $propertiesObject = @{
         "vnetResourceId" = "/subscriptions/$($subscriptionId)/resourceGroups/$($vnet.ResourceGroupName)/providers/Microsoft.Network/virtualNetworks/$($vnetName)"
        }

        $virtualNetwork = New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -Force

    # Now finish joining by getting the VPN package and giving it to the App
    Write-Host "Retrieving VPN Package and supplying to App"
    $packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64

    $packageUri = $packageUri.ToString(); 
    $packageUri = $packageUri.Substring(1, $packageUri.Length-2);

    # Put the VPN client configuration package onto the App
    $PropertiesObject = @{
    "vnetName" = $vnet.Name; "vpnPackageUri" = $packageUri.ToString()
    }
    $date = Get-Date -format "HH:mm tt"

    New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)/primary" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections/gateways" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -WarningAction silentlyContinue -Force  

}

Enjoy
