Manually roll over a Service Fabric cluster certificate

  • आलेख

When a Service Fabric cluster certificate is close to expiring, you need to update the certificate. Certificate rollover is simple if the cluster was set up to use certificates based on common name (instead of thumbprint). Get a new certificate from a certificate authority with a new expiration date. Self-signed certificates are not support for production Service Fabric clusters, to include certificates generated during Azure portal Cluster creation workflow. The new certificate must have the same common name as the older certificate.

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. To get started, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

Service Fabric cluster will automatically use the declared certificate with a further into the future expiration date; when more than one validate certificate is installed on the host. A best practice is to use a Resource Manager template to provision Azure Resources. For non-production environment the following script can be used to upload a new certificate to a key vault and then installs the certificate on the virtual machine scale set:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser -Force

$SubscriptionId  =  <subscription ID>

# Sign in to your Azure account and select your subscription
Login-AzAccount -SubscriptionId $SubscriptionId

$region = "southcentralus"
$KeyVaultResourceGroupName  = "keyvaultgroup"
$VaultName = "cntestvault2"
$certFilename = "C:\users\sfuser\sftutorialcluster20180419110824.pfx"
$certname = "cntestcert"
$Password  = "!P@ssw0rd321"
$VmssResourceGroupName     = "sfclustertutorialgroup"
$VmssName                  = "prnninnxj"

# Create new Resource Group 
New-AzResourceGroup -Name $KeyVaultResourceGroupName -Location $region

# Get the key vault.  The key vault must be enabled for deployment.
$keyVault = Get-AzKeyVault -VaultName $VaultName -ResourceGroupName $KeyVaultResourceGroupName 
$resourceId = $keyVault.ResourceId  

# Add the certificate to the key vault.
$PasswordSec = ConvertTo-SecureString -String $Password -AsPlainText -Force
$KVSecret = Import-AzKeyVaultCertificate -VaultName $vaultName -Name $certName  -FilePath $certFilename -Password $PasswordSec

$CertificateThumbprint = $KVSecret.Thumbprint
$CertificateURL = $KVSecret.SecretId
$SourceVault = $resourceId
$CommName    = $KVSecret.Certificate.SubjectName.Name

Write-Host "CertificateThumbprint    :"  $CertificateThumbprint
Write-Host "CertificateURL           :"  $CertificateURL
Write-Host "SourceVault              :"  $SourceVault
Write-Host "Common Name              :"  $CommName    

Set-StrictMode -Version 3
$ErrorActionPreference = "Stop"

$certConfig = New-AzVmssVaultCertificateConfig -CertificateUrl $CertificateURL -CertificateStore "My"

# Get current VM scale set 
$vmss = Get-AzVmss -ResourceGroupName $VmssResourceGroupName -VMScaleSetName $VmssName

# Add new secret to the VM scale set.
$vmss.VirtualMachineProfile.OsProfile.Secrets[0].VaultCertificates.Add($certConfig)

# Update the VM scale set 
Update-AzVmss -ResourceGroupName $VmssResourceGroupName -Name $VmssName -VirtualMachineScaleSet $vmss  -Verbose

Note

Computes Virtual Machine Scale Set Secrets do not support the same resource id for two separate secrets, as each secret is a versioned unique resource.
