Go Example: Google CloudSQL with CloudSQL Proxy and GORM

main.go

package main

import (
  "github.com/jinzhu/gorm"
  _ "database/sql"
  _ "github.com/GoogleCloudPlatform/cloudsql-proxy/proxy/dialers/mysql"
)

// You can read more in this post: http://forecastcloudy.net/2016/06/28/using-google-cloud-sql-from-go-with-gorm-in-google-container-engine-and-google-compute-engine/
func main() {
  // Using cloudsql-proxy will help you avoid white listing IPs and handling SSL.
  // In this case, it will also run inside your Go program and will not require
  // an additional process or container.
  
  // Connection String details:
  // * user       - the user created inside the DB. You can see more details on how to create it without password here: 
  //                https://cloud.google.com/sql/docs/sql-proxy#flags
  // * project-id - your project id
  // * zone       - your general zone (us-central1/us-west1/etc)
  // * db-name    - the name of the database instance as it appears in the console
  var dbConnectionString = "user@cloudsql(project-id:zone:instance-name)/db-name?charset=utf8&parseTime=True&loc=UTC"
  
  var db *gorm.DB
  var err error
  if db, err = gorm.Open("mysql", dbConnectionString); err != nil {
    panic(err)
  }
}

It's now in the docs, towards the bottom: https://gorm.io/docs/connecting_to_the_database.html

Thanks. It's nice to know. Thanks for sending the link!
