Now I want to deploy a rails app to Google Container Engine. And use Google Cloud SQL as database.

When I tried to connect Google Cloud SQL from Google Container Engine, I got this error:

ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0

Here is a document to solve that, but there is no information about Google Container Engine:

https://cloud.google.com/sql/docs/diagnose-issues#connection

The Google Cloud SQL access SSL connect for dynamically assigned IP addresses:

https://cloud.google.com/sql/docs/access-control#dynamicIP

So I need to create a client certificate for mysql instance:

https://cloud.google.com/sql/docs/configure-ssl-instance

Then connect it this way:

shell> mysql --ssl-ca=server-ca.pem --ssl-cert=client-cert.pem --ssl-key=client-key.pem \
         --host=instance-IP --user=user-name --password

https://cloud.google.com/sql/docs/mysql-client#connect

But I want to connect Google Cloud SQL by mysql database url from my program on Google Container Engine:

mysql2://myapp:password@1.2.3.4/myapp?checkout_timeout=20000

How to attach --ssl-ca, --ssl-cert, --ssl-key with this method?
