Documentation

Overview

Package gcpmysql provides connections to managed MySQL Cloud SQL instances. See https://cloud.google.com/sql/docs/mysql/ for more information.

URLs

For mysql.Open, gcpmysql registers for the scheme "gcpmysql". The default URL opener will create a connection using the default credentials from the environment, as described in https://cloud.google.com/docs/authentication/production. To customize the URL opener, or for more details on the URL format, see URLOpener.

See https://gocloud.dev/concepts/urls/ for background information.

Example

package main

import (
	"context"
	"log"

	"github.com/hy9be/gocloud/mysql"
	_ "github.com/hy9be/gocloud/mysql/gcpmysql"
)

func main() {
	// PRAGMA: This example is used on gocloud.dev; PRAGMA comments adjust how it is shown and can be ignored.
	// PRAGMA: On gocloud.dev, add a blank import: _ "github.com/hy9be/gocloud/mysql/gcpmysql"
	// PRAGMA: On gocloud.dev, hide lines until the next blank line.
	ctx := context.Background()

	// Replace this with your actual settings.
	db, err := mysql.Open(ctx,
		"gcpmysql://user:password@example-project/region/my-instance01/testdb")
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

	// Use database in your program.
	db.Exec("CREATE TABLE foo (bar INT);")
}
