Cloud SQL is now supported by the fully managed version of Cloud Run (Cloud Run on GKE users were already able to use Cloud SQL using a private IP)

The feature is currently in alpha, so you need to use gcloud alpha (it will be in gcloud beta within 10 days):

To get started:

• if you do not have one already, create a Cloud SQL instance.
• make sure that the Cloud SQL admin API
• deploy a new revision of your Cloud Run service with gcloud alpha and the following flag: $ gcloud alpha run services update --add-cloudsql-instances [INSTANCE_CONNECTION_NAME] Where is INSTANCE_CONNECTION_NAME is of the type project:region:instancename.

When yo do this, Cloud Run will activate and configure the Cloud SQL proxy for you. You should then connect to it via the /cloudsql/[INSTANCE_CONNECTION_NAME] Unix socket.
