Azure Built In Tagging Policy. Update Resource by Inheriting Subscription Tag

Ensure your Azure Resources are tagged with the Tag from Subscription

In this example we have the following requirements

• The costCentre tag has been manually added to the Subscription
• Every resource must be created with a costCentre
• The CostCentre tag must exist on the resources
• The Resources inherit from the container they are in, but can be manually overridden

Costcentre Tag Configuration

• Modify Resources to add the CostCentre tag from the parent Subscription where missing

Time to assign a new Policy

No Need to select a Resource group because they haven’t been created yet and this applies to all resource groups that have yet to be created

Choose Inherit a tag from the subscription if missing

The Assignment Name has been changed to include the tag

And the tab name is added as a parameter

We need a Managed Identity because this has a modify effect

Then go to Review + Create and Create

Test the New Modify Policy

This is the tag on the Subscription

Create a New Resource Group (And remember to apply any tags of Policies you have already set

Within this Resource Group, Create a New Resource (Dont add the tag)

Once created, the Resource will inherit the Tag from the Subscription
