PowerShell scripts for Azure deployment

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

• Provision NetScaler VPX in Standalone Mode
• Configure NetScaler VPX HA with Azure External Load Balancer
• Configure NetScaler VPX HA with Azure Internal Load Balance

Provision NetScaler VPX in Standalone Mode

1.   Creating 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

2.   Creating 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

3.   Creating 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.  Creating 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

5.   Creating 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

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

Make sure that the private (static) IP address you add to the VM should 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.   Creating 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.    Getting 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 login 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:

$offerName=”netscalervpx110-6531”

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

8.   Creating 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

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

Provision NetScaler VPX in HA with Azure External Load Balancer

Log on to AzureRmAccount using your Azure user credentials.

1)     Creating a resource group

The location specified here is the default location for resources in that resource group. Make sure that all commands used 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-LB-NS”

$locName = “West US”

New-AzureRmResourceGroup -Name $rgName -Location $locName

2)     Creating 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

3)     Creating an availability set

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)     Creating a virtual network

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

$vnetName = “LBVnet”

$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

$vnet=New-AzureRmVirtualNetwork -Name $vnetName -ResourceGroupName $rgName -Location $locName -AddressPrefix $vnetAddressPrefix -Subnet $frontendSubnet,$backendSubnet`

Note: Choose the AddressPrefix parameter value as per your requirement.

Assign front end and back end subnet to the virtual network that you created earlier in this step.

If the front end subnet is the first element of array vnet, subnetId should be $vnet.Subnets[0].Id.

If the front end subnet is the second element in the array, the subnetId should be $vnet.Subnets[1].Id, and so on..

5)     Configuring front end IP address and creating back end address pool

Configure a front end IP address for the incoming load balancer network traffic and create a back end address pool to receive the load balanced traffic.

$pubName=”PublicIp1”

$publicIP1 = New-AzureRmPublicIpAddress -Name $pubName -ResourceGroupName $rgName -Location $locName -AllocationMethod Static -DomainNameLabel nsvpx

Note: Check for the availability of the value for DomainNameLabel.

$FIPName = “ELBFIP”

$frontendIP1 = New-AzureRmLoadBalancerFrontendIpConfig -Name $FIPName -PublicIpAddress $publicIP1

$BEPool = “LB-backend-Pool”

$beaddresspool1= New-AzureRmLoadBalancerBackendAddressPoolConfig -Name $BEPool

8)     Creating a health probe

Create a TCP health probe with port 9000 and interval 5 seconds.

$healthProbe = New-AzureRmLoadBalancerProbeConfig -Name HealthProbe -Protocol Tcp -Port 9000 -IntervalInSeconds 5 -ProbeCount 2

9)     Creating a load balancing rule

Create a LB rule for each service that you are load balancing.

For example:

You can use the following example to load balance http service.

$lbrule1 = New-AzureRmLoadBalancerRuleConfig -Name “HTTP-LB” -FrontendIpConfiguration $frontendIP1 -BackendAddressPool  $beAddressPool1 -Probe $healthProbe -Protocol Tcp -FrontendPort 80 -BackendPort 80

10)     Creating inbound NAT rules

Create NAT rules for services that you are not load balancing.

For example, when creating a SSH access to a NetScaler VPX instance.

Note: Protocol-FrontEndPort-BackendPort triplet should not be the same for two NAT rules.

$inboundNATRule1= New-AzureRmLoadBalancerInboundNatRuleConfig -Name SSH1 -FrontendIpConfiguration $frontendIP1 -Protocol TCP -FrontendPort 22 -BackendPort 22

$inboundNATRule2= New-AzureRmLoadBalancerInboundNatRuleConfig -Name SSH2 -FrontendIpConfiguration $frontendIP1 -Protocol TCP -FrontendPort 10022 -BackendPort 22

11)     Creating a load balancer entity

Create the load balancer adding all objects (NAT rules, load balancer rules, probe configurations) together.

$lbName=”ELB”

$NRPLB = New-AzureRmLoadBalancer -ResourceGroupName $rgName -Name $lbName -Location $locName -InboundNatRule $inboundNATRule1, $inboundNATRule2 -FrontendIpConfiguration $frontendIP1 -LoadBalancingRule $lbrule1 -BackendAddressPool $beAddressPool1 -Probe $healthProbe

12)     Creating a NIC

Create two NICs and associate each NIC with each VPX instance

a)      NIC1 with VPX1

For example:

$nicName=”NIC1”

$lbName=”ELB”

$bePoolIndex=0  

* Rule indexes starts from 0.

$natRuleIndex=0

$subnetIndex=0

* Frontend subnet index

$lb=Get-AzureRmLoadBalancer -Name $lbName -ResourceGroupName $rgName

$nic1=New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -Subnet $vnet.Subnets[$subnetIndex] -LoadBalancerBackendAddressPool $lb.BackendAddressPools[$bePoolIndex] -LoadBalancerInboundNatRule $lb.InboundNatRules[$natRuleIndex]

b)      NIC2 with VPX2

For example:

$nicName=”NIC2”

$lbName=”ELB”

$bePoolIndex=0

$natRuleIndex=1

* Second Inbound NAT (SSH) rule we need to use

$subnetIndex=0

* Frontend subnet index

$lb=Get-AzureRmLoadBalancer -Name $lbName -ResourceGroupName $rgName

$nic2=New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $rgName -Location $locName -Subnet $vnet.Subnets[$subnetIndex] -LoadBalancerBackendAddressPool $lb.BackendAddressPools[$bePoolIndex] -LoadBalancerInboundNatRule  $lb.InboundNatRules[$natRuleIndex]

13)     Creating NetScaler VPX instances

Create two NetScaler VPX instances as part of the same resource group and availability set, and attach it to the external load balancer.

a)     NetScaler VPX instance 1

For example:

$vmName=”VPX1”

$vmSize=”Standard_A3”

$pubName=”citrix”

$offerName=”netscalervpx110-6531”

$skuName=”netscalerbyol”

14)     Configuring 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.

Provision NetScaler VPX in HA with Azure Internal Load Balancer

Log on to AzureRmAccount using your Azure user credentials.

1)     Creating a resource 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>”

$avName=”<availability set name>”

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

4)     Creating a virtual network

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

$vnetName = “LBVnet”

$vnetAddressPrefix=”10.0.0.0/16”

$FrontendAddressPrefix=”10.0.1.0/24”

$BackendAddressPrefix=”10.0.2.0/24”

$vnet=New-AzureRmVirtualNetwork -Name $vnetName -ResourceGroupName $rgName -Location $locName -AddressPrefix $vnetAddressPrefix -Subnet $frontendSubnet,$backendSubnet`

$frontendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix $FrontendAddressPrefix

$backendSubnet=New-AzureRmVirtualNetworkSubnetConfig -Name backendSubnet -AddressPrefix $BackendAddressPrefix

Note: Choose the AddressPrefix parameter value as per your requirement.

Assign front end and back end subnet to the virtual network that you created earlier in this step.

If the front end subnet is the first element of array vnet, subnetId should be $vnet.Subnets[0].Id.

If the front end subnet is the second element in the array, the subnetId should be $vnet.Subnets[1].Id, and so on..

5)     Creating an back end address pool
