PowerShell Runbook to auto start and shut down Azure VM in a resource management group

Last post listed the sample code to start and shut down Azure VM remotely.

Here is the PowerShell runbook script which can be scheduled in Azure.

This is more stable, simpler and easier to manage.

$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Add-AzureRMAccount -ServicePrincipal -Tenant $Conn.TenantID `
  -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint

Write-Output "Connection established."

$vmname = 'AZ532-test1'
$VMDetail = Get-AzureRMVM -ResourceGroupName $ResourceGroupName -Name $VmName -Status
$vmPowerstate = $VMDetail[1].Code
Write-Verbose "vmPowerstate: $vmPowerstate"

if ($vmPowerstate -like "PowerState/running"){
write-host "VM '$vmname' is ""$vmPowerstate"". Skip."
}
else{
write-host "Starting VM '$vmname'"
Start-AzureRMVM -ResourceGroupName $ResourceGroupName -Name $VmName -Verbose
}

# if ($vmPowerstate -like "PowerState/running"){

#  write-host "Stopping VM '$vmname'"

#  Stop-AzureRMVM -ResourceGroupName $ResourceGroupName -Name $VmName -Verbose -Force

# }

# else{

#  write-host "VM '$vmname' is ""$vmPowerstate"". Skip."

# }

Write-Output "VM $vmname is started."

==============

Azure classic VM is similar:

$ConnectionAssetName = "AzureClassicRunAsConnection"
$connection = Get-AutomationConnection -Name $connectionAssetName        
Write-Verbose "Get connection asset: $ConnectionAssetName" -Verbose
$Conn = Get-AutomationConnection -Name $ConnectionAssetName
if ($Conn -eq $null)
{
    throw "Could not retrieve connection asset: $ConnectionAssetName. Assure            that this asset exists in the Automation account."
}

Write-Output "Connection established."

$CertificateAssetName = $Conn.CertificateAssetName
Write-Verbose "Getting the certificate: $CertificateAssetName" -Verbose
$AzureCert = Get-AutomationCertificate -Name $CertificateAssetName
if ($AzureCert -eq $null)
{
    throw "Could not retrieve certificate asset: $CertificateAssetName.       Assure that this asset exists in the Automation account."
}

Write-Verbose "Authenticating to Azure with certificate." -Verbose
Set-AzureSubscription -SubscriptionName $Conn.SubscriptionName -SubscriptionId $Conn.SubscriptionID -Certificate $AzureCert 
Select-AzureSubscription -SubscriptionId $Conn.SubscriptionID

$vmname = 'hvEF4'
$vm = Get-AzureVM | Where-Object { $_.Name -eq $vmname }
write-host "AzureVM: "
$vm | fl *

# if ($vm.PowerState -eq "Started"){
# write-host "Stopping VM '$vmname'"
# $vm | Stop-AzureVM -Force
# }
# else{
# write-host "VM '$vmname' is ""$($vm.PowerState)"". Skip."
# }

if ($vm.PowerState -eq "Started"){
write-host "VM '$vmname' is ""$($vm.PowerState)"". Skip."
}
else{
write-host "Starting VM '$vmname'"
$vm | Start-AzureVM
}

write-host "done."
