Email Alert when a specific file is available in GCP bucket

Question

I need to get an email alert to my email when a specific file in GCP bucket is arrived/available. Which functionality/tool i can use in GCP.

Answer 1

You can look at the following approach:

• Use Cloud Functions and specifically the Google Cloud Storage Trigger with the default event google.storage.object.finalize. Check out sample code here.
• In the function code, you can pass on relevant file details and use a 3rd party email service like SendGrid, etc to send an email. Check out instructions/code here to send out email: https://cloud.google.com/security-command-center/docs/how-to-enable-real-time-notifications

Answer 2

@Romin solution will work, you can also have a look to Eventarc and Cloud Run.

However, you can use a hack fully managed by Google Cloud.

Firstly, activate the Cloud Storage Audit Logs (be careful, if you have a lot of activity, it can generate a lot of logs and be costly).

Then, create a log based metrics on the audit logs that mentionned the file creation and with the filter on the file path (you can use the =~ operator for regex filtering)

Finally, create an alert on that metrics, and send an email when the alert is triggered
