Failure when creating service fabric cluster with powershell - powershell

Question

I'm trying to create a service fabric cluster with a powershell script. Here's the script:
Param(
[Parameter(HelpMessage="Azure user name")]
[String]$azUserName,
[Parameter(HelpMessage="Azure password")]
[String]$azPassword,
[Parameter(HelpMessage="What is the resource group name?")]
[String]$ResourceGroupName="sfLinuxClusterRg",
[Parameter(HelpMessage="What is the key vault group name?")]
[String]$KeyVaultResourceGroupName="KeyVaultRg",
[Parameter(HelpMessage="Where is the azure location?")]
[String]$Location="uksouth",
[Parameter(HelpMessage="what is the key vault group?")]
[String]$VaultGroupName="linuxclusterkeyvaultgroup",
[Parameter(HelpMessage="Where is the certificate stored locally?")]
[String]$CertFileName="certificate.pfx",
[Parameter(HelpMessage="What is the subscription id?")]
[String]$SubscriptionId,
[Parameter(HelpMessage="What is the tenant id?")]
[String]$TenantId
)
Function DecryptSecureString([SecureString] $secureText){
return [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($secureText))
}
Function CreateKeyVaultCert(){
try{
Select-AzureRmSubscription -SubscriptionId $SubscriptionId `
-TenantId $TenantId
# Create a Resource Group to hold your Key Vault(s)
# Note this should be separate from your other resources so you can delete those other resource groups without impacting your registered certs
New-AzureRmResourceGroup -Name $KeyVaultResourceGroupName -Location uksouth -Force
# Create a Key Vault to hold your secrets
New-AzureRmKeyVault -VaultName $vaultName -ResourceGroupName $KeyVaultResourceGroupName `
-Location uksouth -EnabledForDeployment `
-EnabledForDiskEncryption -EnabledForTemplateDeployment
# Have Key Vault create the certificate with a simple policy
$policy = New-AzureKeyVaultCertificatePolicy `
-SubjectName "CN=cluster123.uksouth.cloudapp.azure.com" `
-IssuerName Self -ValidityInMonths 12
Add-AzureKeyVaultCertificate -VaultName $vaultName -Name cert1 -CertificatePolicy $policy
Set-AzureRmKeyVaultAccessPolicy -VaultName $vaultName -EnabledForDeployment
Set-AzureRmKeyVaultAccessPolicy -VaultName $vaultName -EmailAddress $azUserName -PermissionsToSecrets Get
}
catch{
Write-Host $_.Exception.Message
exit
}
}
$azPassword = $azPassword | ConvertTo-SecureString -AsPlainText -Force
Import-AzureRmContext -Path "C:\stuff\AzureProfile.json"
$Date = Get-Date
$VaultName="VaultLearn" + $Date.ToString("hhmmss")
# sign in to your Azure account and select your subscription
$certName = "CN=cluster123.uksouth.cloudapp.azure.com"
$clustersize=5
$clustername = "cluster123" + $Date.ToString("hhmmss")
$adminuser="admin"
$vmsku = "Standard_D2_v2"
$os = "UbuntuServer1604"
Select-AzureRmSubscription -SubscriptionId $SubscriptionId
CreateKeyVaultCert
New-AzureRmServiceFabricCluster -Name $clustername `
-ResourceGroupName $ResourceGroupName `
-Location uksouth `
-ClusterSize $clustersize `
-VmUserName $adminuser -VmPassword $azPassword `
-CertificateSubjectName $certName `
-CertificatePassword $azPassword `
-VmSku $vmsku `
-CertificateOutputFolder 'C:\stuff' `
-OS $os `
-KeyVaultName $VaultName
Write-Host "Created service fabric cluster in resource group $ResourceGroupName"
#Add-AzureRmAccount
# $path = "C:\stuff\AzureProfile.json"
# Save-AzureRmContext -Path $path -Force
I keep getting the error:
New-AzureRmServiceFabricCluster : The name 'VaultLearn090903' is already in use.
This is really weird, because I'm pretty sure yesterday this script at least attempted to create the cluster, although I was getting another error about Ubuntu image not being found. What could be causing this error?
By the way, in order to run this script, I have previously run this code:
Add-AzureRmAccount
$path = "C:\stuff\AzureProfile.json"
Save-AzureRmContext -Path $path -Force
which has cached my azure credentials locally.
I have specifically added two statements into the script to add a policy for access to the keyvault:
Set-AzureRmKeyVaultAccessPolicy -VaultName $vaultName -EnabledForDeployment
Set-AzureRmKeyVaultAccessPolicy -VaultName $vaultName -EmailAddress $azUserName -PermissionsToSecrets Get
I know this is probably overkill, but I'm trying to get rid of this problem.
The other weird thing is I have tried the Azure Sample Github repo
I'm at a loss for how I can continue with service fabric.

Answer 1

For completeness:
I managed to get something different working by going to the azure portal, creating a service fabric cluster and downloading the ARM template (which includes some powershell scripts).
thanks
