Tags - Automatically tag the creator of a resource or resource group¶
It is strongly recommended to always use
resource-typefilter when using
Tag operation is allowed only for ARM resources supported by Cloud Custodian, error message is logged for all unknown and unsupported resources.
In non-event mode (periodic function or local execution), the action will look in Azure Activity Logs up to 90 days prior to execution to find the user email (default). It will attempt to identify the first user or Service Principal that performed the ‘write’ operation for each resource.
In event mode, the action will use the data from the event to determine the user or principal that performed the action. The days option is not applicable in this mode.
Note: Resource Groups aren’t a part of
armresourcetype, so tags needs to be added separately.
Note: Service Principals do not have email addresses and their tag values will be the application id.
Tag all resource groups with the email address of the creator. The email address is taken from the oldest user to ‘write’ the resource group within the last 10 days.

Event grid triggered policy to tag all virtual machines and storage accounts with the creator email. The creator email is contained in the event message, so days is not needed.

Note: 'resource-type' filter is not required because policy is not triggered by other resources. actions: - type: auto-tag-user tag: CreatorEmail
