Control updates with Maintenance Configurations and the Azure portal
Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets
With Maintenance Configurations, you can now take more control over when to apply updates to various Azure resources. This topic covers the Azure portal options for creating Maintenance Configurations. For more about benefits of using Maintenance Configurations, its limitations, and other management options, see Managing platform updates with Maintenance Configurations.
Create a Maintenance Configuration
Sign in to the Azure portal.
Search for Maintenance Configurations.
In the Basics tab, choose a subscription and resource group, provide a name for the configuration, choose a region, and select one of the scopes we offer which you wish to apply updates for. Click Add a schedule to add or modify the schedule for your configuration.
Certain virtual machine types and schedules will require a specific kind of scope. Check out maintenance configuration scopes to find the right one for your virtual machine.
In the Schedule tab, declare a scheduled window when Azure will apply the updates on your resources. Set a start date, maintenance window, and recurrence if your resource requires it. Once you create a scheduled window you no longer have to apply the updates manually. Click Next.
Maintenance window duration must be 2 hours or longer.
In the Machines tab, assign resources now or skip this step and assign resources later after maintenance configuration deployment. Click Next.
Add tags and values. Click Next.
Review the summary. Click Create.
After the deployment is complete, click Go to resource.
Assign the configuration
On the details page of the maintenance configuration, click Machines and then click Add Machine.
Select the resources that you want the maintenance configuration assigned to and click Ok. The VM needs to be running to assign the configuration. An error occurs if you try to assign a configuration to a VM that is stopped.
You can verify that the configuration was applied correctly or check to see any maintenance configuration that is currently assigned to a machine by going to the Maintenance Configurations and checking under the Machines tab. You should see any machine you have assigned the configuration in this tab.
Check for pending updates
You can check if there are any updates pending for a maintenance configuration. In Maintenance Configurations, on the details for the configuration, click Machines and check Maintenance status.
Delete a maintenance configuration
To delete a configuration, open the configuration details and click Delete.
