On Dataflow you cannot whitelist an IP to enable Dataflow to access a SQL instance. If you would be using Java, the easiest way would be to use JdbcIO / JDBC socket factory.

But since you're using Python, then mimicking the implementation of JdbcIO.read() using Python-specific database connectivity facilities would help. There's this related question with a workaround after changing some Cloud SQL settings and adding related python codes.

If this seems complex, alternatively you can export data from Cloud SQL to Cloud Storage and then load from Cloud Storage.
