Additional PowerShell scripts for Azure deployment

This section provides the PowerShell cmdlets with which you can perform the following configurations in Azure PowerShell:

• Provision a NetScaler VPX standalone instance
• Provision a NetScaler VPX pair in a high availability setup with an Azure external load balancer
• Provision a NetScaler VPX pair in a high availability setup with Azure internal load balancer

Also see the following topics for configurations that you can perform by using PowerShell commands:

• Configure a high-availability setup with multiple IP addresses and NICs by using PowerShell commands
• Configure GSLB on NetScaler VPX instances
• Configure GSLB on a NetScaler active-standby high-availability setup
• Configure multiple IP addresses for a NetScaler VPX instance in standalone mode by using PowerShell commands

Provision a NetScaler VPX standalone instance

1. Create a resource group

   The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. The location specified here is the default location for resources in that resource group. Make sure all commands to create a load balancer use the same resource group.

   $rgName="<resource group name>" $locName="<location name, such as West US> New-AzureRmResourceGroup -Name $rgName -Location $locName

   For example:

   $rgName = "ARM-VPX"
   $locName = "West US"
   New-AzureRmResourceGroup -Name $rgName -Location $locName
   <!--NeedCopy-->
   

2. Create a storage account

   Choose a unique name for your storage account that contains only lowercase letters and numbers.

   $saName="<storage account name>" $saType="<storage account type>", specify one: Standard_LRS, Standard_GRS, Standard_RAGRS, or Premium_LRS New-AzureRmStorageAccount -Name $saName -ResourceGroupName $rgName -Type $saType -Location $locName

   For example:

   $saName="vpxstorage"
   $saType="Standard\_LRS"
   New-AzureRmStorageAccount -Name $saName -ResourceGroupName $rgName -Type $saType -Location $locName
   <!--NeedCopy-->
   

3. Create an availability set

   Availability set helps to keep your virtual machines available during downtime, such as during maintenance. A load balancer configured with an availability set ensures that your application is always available.

   $avName="<availability set name>"

   New-AzureRmAvailabilitySet -Name $avName -ResourceGroupName $rgName -Location $locName

4. Create a virtual network

   Add a new virtual network with at least one subnet, if the subnet was not created previously.

   $FrontendAddressPrefix="10.0.1.0/24" $BackendAddressPrefix="10.0.2.0/24" $vnetAddressPrefix="10.0.0.0/16" $frontendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix $FrontendAddressPrefix $backendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name backendSubnet -AddressPrefix $BackendAddressPrefix New-AzureRmVirtualNetwork -Name TestNet -ResourceGroupName $rgName -Location $locName -AddressPrefix $vnetAddressPrefix -Subnet $frontendSubnet,$backendSubnet

   For example:

   $frontendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix $FrontendAddressPrefix
   
   $backendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name backendSubnet -AddressPrefix $BackendAddressPrefix
   
   New-AzureRmVirtualNetwork -Name TestNet -ResourceGroupName $rgName -Location $locName -AddressPrefix $vnetAddressPrefix -Subnet $frontendSubnet,$backendSubnet
   <!--NeedCopy-->
   

5. Create a NIC

   Create a NIC and associate the NIC with the NetScaler VPX instance. The front end Subnet created in the above procedure is indexed at 0 and the back end Subnet is indexed at 1. Now create NIC in one of the three following ways:

   a) NIC with Public IP address

   $nicName="<name of the NIC of the VM>"

   $pip = New-AzureRmPublicIpAddress -Name $nicName -ResourceGroupName $rgName -Location $locName -AllocationMethod Dynamic

   $nic = New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -SubnetId $vnet.Subnets[$subnetIndex].Id -PublicIpAddressId $pip.Id

   b) NIC with Public IP and DNS label

   $nicName="<name of the NIC of the VM>"

   $domName="<domain name label>"

   $pip = New-AzureRmPublicIpAddress -Name $nicName -ResourceGroupName $rgName -DomainNameLabel $domName -Location $locName -AllocationMethod Dynamic

   Before assigning $domName, check it is available or not by using command:

   Test-AzureRmDnsAvailability -DomainQualifiedName $domName -Location $locName

   $nic = New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -SubnetId $vnet.Subnets[$subnetIndex].Id -PublicIpAddressId $pip.Id

   For example:

   $nicName="frontendNIC"
   
   $domName="vpxazure"
   
   $pip = New-AzureRmPublicIpAddress -Name $nicName -ResourceGroupName $rgName -DomainNameLabel $domName -Location $locName -AllocationMethod Dynamic
   
   $nic = New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -SubnetId $vnet.Subnets\[0\].Id -PublicIpAddressId $pip.Id
   <!--NeedCopy-->
   

   c) NIC with Dynamic Public Address and Static Private IP address

   Make sure that the private (static) IP address you add to the VM must be the same range as that of the subnet specified.

   $nicName="<name of the NIC of the VM>"

   $staticIP="<available static IP address on the subnet>"

   $pip = New-AzureRmPublicIpAddress -Name $nicName -ResourceGroupName $rgName -Location $locName -AllocationMethod Dynamic

   $nic = New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -SubnetId $vnet.Subnets[$subnetIndex].Id -PublicIpAddressId $pip.Id -PrivateIpAddress $staticIP

6. Create a virtual object

   $vmName="<VM name>"

   $vmSize="<VM size string>"

   $avSet=Get-AzureRmAvailabilitySet -Name $avName -ResourceGroupName $rgName

   $vm=New-AzureRmVMConfig -VMName $vmName -VMSize $vmSize -AvailabilitySetId $avset.Id

7. Get the NetScaler VPX image

   $pubName="<Image publisher name>"

   $offerName="<Image offer name>"

   $skuName="<Image SKU name>"

   $cred=Get-Credential -Message "Type the name and password of the local administrator account."

   Provide your credentials that is used to log in into VPX

   $vm=Set-AzureRmVMOperatingSystem -VM $vm -Linux -ComputerName $vmName -Credential $cred -Verbose

   $vm=Set-AzureRmVMSourceImage -VM $vm -PublisherName $pubName -Offer $offerName -Skus $skuName -Version "latest"

   $vm=Add-AzureRmVMNetworkInterface -VM $vm -Id $nic.Id

   For example:

   $pubName="citrix"

   The following command is used for displaying all offers from Citrix:

   Get-AzureRMVMImageOffer -Location $locName -Publisher $pubName | Select Offer
   
   $offerName="netscalervpx110-6531"
   <!--NeedCopy-->
   

   The following command is used to know SKU offered by publisher for specific offer name:

   Get-AzureRMVMImageSku -Location $locName -Publisher $pubName -Offer $offerName | Select Skus

8. Create a virtual machine

   $diskName="<name identifier for the disk in Azure storage, such as OSDisk>"

   For example:

   $diskName="dynamic"
   
   $pubName="citrix"
   
   $offerName="netscalervpx110-6531"
   
   $skuName="netscalerbyol"
   
   $storageAcc=Get-AzureRmStorageAccount -ResourceGroupName $rgName -Name $saName
   
   $osDiskUri=$storageAcc.PrimaryEndpoints.Blob.ToString() + "vhds/" + $diskName  + ".vhd"
   
   $vm=Set-AzureRmVMOSDisk -VM $vm -Name $diskName -VhdUri $osDiskUri -CreateOption fromImage
   <!--NeedCopy-->
   

   When you create VM from Images present in marketplace, use the following command to specify the VM plan:

   Set-AzureRmVMPlan -VM $vm -Publisher $pubName -Product $offerName -Name $skuName

   New-AzureRmVM -ResourceGroupName $rgName -Location $locName -VM $vm

12. Configure the virtual machines

    When both the NetScaler VPX instances start, then connect to both NetScaler VPX instances using the SSH protocol to configure the virtual machines.

    a) Active-Active: Run the same set of configuration commands on the command line of both the NetScaler VPX instances.

    b) Active-Passive: Run this command on the command line of both the NetScaler VPX instances.

    add ha node #nodeID <nsip of other NetScaler VPX>

    In Active-Passive mode, run configuration commands on the primary node only.
