Before you can run or deploy the sample, you will need to create a Cloud SQL database:
Create a Cloud SQL instance. You can do this from the Google Developers
Console or via the
Cloud SDK. To create it via the SDK,
use the following command:
Create a new user and database for the application. The easiest way to do
this is via the Google Developers Console.
Alternatively, you can use MySQL tools such as the command line client or
workbench.
Update the connection string in app.yaml with the username, password,
hostname and database name of the Cloud SQL instance you just created.
Running locally
To run locally, set the environment variables before running the sample:
$ export MYSQL_CONNECTION=user:password@tcp([host]:3306)/dbname
$ go run cloudsql.go
