Incoming connections to Cloud SQL database instances do not use SSL

Description

Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL and SQL Server. It offers data encryption at rest and in transit, Private connectivity with VPC and user-controlled network access with firewall protection. Cloud SQL creates a server certificate automatically when a new instance is created.

We recommend you enforce all connections to use SSL/TLS.

    # type. See argument reference below.
    tier = "db-f1-micro"
