You can write functions that integrate with Cloud databases by importing the
appropriate Cloud Client Libraries for your chosen database into your source code.
To deploy and trigger the function, you can use either:
Cloud Run functions (Recommended)
The Cloud Functions gcloud CLI
This page provides more information for learning about connecting with a Cloud
database using Cloud Run.
Connect to Cloud SQL
Learn how to add database functionality to your Cloud Run with
Cloud SQL:
For connecting to a MySQL instance from a service running in
Cloud Run, see Connect from Cloud Run.
For connecting to a PostgreSQL instance from a service running in
Cloud Run, see Connect from Cloud Run.
For connecting to a SQL Server instance from a service running in
Cloud Run, see Connect from Cloud Run.
