Thank you for your post and I apologize for the delayed response!
I understand that you're trying to create alerts based off a Certificate's expiration date without having to use any automation such as a runbook, webhook, etc. To hopefully help point you in the right direction or resolve your issue, I'll share my findings below.
Findings:
You can automate alerts without the need for additional automation resources (i.e. runbook/webhook) by adding certificate contact(s) to your Key Vault and configuring notifications for certificate life events.
-
Note: The contact's information is shared by all the certificates in the key vault and a notification is sent to all the specified contacts for an event for any certificate in the key vault.
Get notified about certificate expiration:
-
Note: For existing Certificates, you'll need to manually update the Issuance Policy from Automatic to Email.
If a certificate's policy is set to auto renewal, then a notification is sent on the following events:
- Before certificate renewal
- After certificate renewal, stating if the certificate was successfully renewed, or if there was an error, requiring manual renewal of the certificate.
When a certificate policy is set to be manually renewed (email only), a notification is sent when it's time to renew the certificate.
