Flexible vm CloudSQL setup

[atishpatel]

I'm setting up an Go App Engine flexible environment that can connect to Second Gen Cloud SQL instance.

The method provided in this repo requires authorizations for 0.0.0.0/0 so it's really insecure.

There is suppose to be another method: https://cloud.google.com/sql/docs/app-engine-connect#gaev2-csqlv2
However, it leads to an unknown network cloudsql or if the cloudsql dialer is added cloudsql: not supported in App Engine "flexible environment" error. (here is the reason for the second error https://github.com/golang/appengine/blob/master/cloudsql/cloudsql_vm.go)

Is the document on the cloud.google.com page suppose to work? If so, could the example in this repo be updated to show how to do this?

You're right. Thanks for the report. I noticed this today, as well. I couldn't get it to work, either.
