First you should create a Cloud Sql instance and give it a name. Clous Sql gives you an IP address. Then you can either import your database from inside google cloud sql or use MySql Workbench and the given ip to connect to your Cloud sql and import your db using workbench:

1. From Cloud Sql:

First you need to create a bucket and give it a name. Then upload your db into the bucket. Cloud Sql can't import db directly from other directories. then from Cloud sql -> import enter address of your database inside your bucket.

ex: gs://myBucket/mydb.sql

Note: don't forget to put USE XXX (XXX name of your db) inside mydb.sql so that Cloud Sql knows which databse you are talking about.

2. Import using Workbench:

• Go to Cloud Sql -> Access Control -> Authorization and add the IP address of your computer that you want to use to connect to the Cloud Sql. Cloud Sql does not allow connections from unknown sources.(Security)

• Then from Cloud Sql -> Access Control -> Users you should add your database user name and password (root is default).

• You can check your Cloud Sql Ip address from Cloud Sql -> Access Control -> IP Address

• Open MySql Workbench and create a new connection. Enter IP address of your Cloud Sql and user name and password for your database and click test connection. Congratulations! now you are connected to Cloud Sql.

• Now you can create a new database or import an existing db as usual.

• Then go back to Cloud Sql -> Databases and check your imported database.

I hope this helps.
