Azure VMs turn off & on by schedule

save-timeIn this post I’ll show how to setup Azure VMs turn off & on by schedule using Azure Automation which is really useful for cost saving.

We’ll use dozen of actions to manage this task.

However, not all actions can be managed with PowerShell, so we’ll use old Azure portal a few times.

Initially I used one big script, but for this demo I decided to split it to make things simple.

In this particular example I’ll use two VMs running in the same cloud service.

Create management certificate

We’ll use Windows-based machine for all actions in this example, so we’ll use makecert utility (if you don’t have it yet, just install Windows ADK).

[pastacode lang=”bash” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”createCertificate.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

Upload management certificate to Azure

This step requires manual action, so let’s go to the Old portal > Setting > Management certificates and click Upload:

If you find how it can be done with PowerShell please let me know.

Create Automation account

We’ll start with Azure PowerShell now (if you don’t have it, you can use this link – https://azure.microsoft.com/en-us/documentation/articles/powershell-install-configure/)

Let’s perform login to Azure:

Add-AzureAccount

 

So far we’re ready to create Azure automation account and assign certificate:

[pastacode lang=”bash” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”createAutomationAccount.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

Create Runbooks and Schedule

We’ll use two scripts to start VM, strictly speaking, first one is Azure runbook and second is for pushing runbook to Azure. With stop VM it’s exactly the same.

I don’t like to keep stuff hardcoded, so some variables will be placed in Automation account Assets and some will be suited as parameters.

Here’s another problem with PowerShell – I wasn’t able to put variable content with cyrillic symbols. It’s possible to find workaround, but let’s just save some time and use the old portal again.

Go to the Automation > automationaccount > Assets and click Add setting > Add variable (string):

Let’s take a look at Azure Start VM Runbook:

[pastacode lang=”bash” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”Start-VM-Runbook.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

Azure Stop VM Runbook is very similar, but we don’t want to lose our IP addresses (StayProvisioned parameter is used for it):

[pastacode lang=”bash” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”Stop-VM-Runbook.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

We’ll push Start VM Runbook & set execution schedule using createStartRunbook script and here it is:

[pastacode lang=”markup” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”createStartRunbook.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

And almost the same for Stop VM:

[pastacode lang=”bash” user=”kagarlickij” repos=”azure-vm-schedule” path_id=”createStopRunbook.ps1″ revision=”” highlight=”” lines=”” provider=”bitbucket”/]

 

Check results

You can execute runbook manually and see that it works:
