Provision a Citrix ADC 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 Citrix ADC 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 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. 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 Citrix ADC 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"
<!--NeedCopy-->
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
