Go MYSQL Dump

Create MYSQL dumps in Go without the mysqldump CLI as a dependancy.

Simple Example

package main

import (
    "database/sql"
    "fmt"
    "os"

    "github.com/go-sql-driver/mysql"
    "github.com/jamf/go-mysqldump"
)

func main() {
    // Open connection to database
    config := mysql.NewConfig()
    config.User = "your-user"
    config.Passwd = "your-pw"
    config.DBName = "your-db"
    config.Net = "tcp"
    config.Addr = "your-hostname:your-port"

    dumpDir := "dumps"
    dumpFilenameFormat := fmt.Sprintf("%s-20060102T150405", config.DBName) // accepts time layout string and add .sql at the end of file

    if err := os.MkdirAll(dumpDir, 0755); err != nil {
        fmt.Println("Error mkdir:", err)
        return
    }

    db, err := sql.Open("mysql", config.FormatDSN())
    if err != nil {
        fmt.Println("Error opening database:", err)
        return
    }

    // Register database with mysqldump
    dumper, err := mysqldump.Register(db, dumpDir, dumpFilenameFormat)
    if err != nil {
        fmt.Println("Error registering databse:", err)
        return
    }

    // Dump database to file
    if err := dumper.Dump(); err != nil {
        fmt.Println("Error dumping:", err)
        return
    }
    if file, ok := dumper.Out.(*os.File); ok {
        fmt.Println("File is saved to", file.Name())
    } else {
        fmt.Println("It's not part of *os.File, but dump is done")
    }

    // Close dumper, connected database and file stream.
    dumper.Close()
}
