MinIO Go Client SDK for Amazon S3 Compatible Cloud Storage Slack Sourcegraph Apache V2 License

The MinIO Go Client SDK provides simple APIs to access any Amazon S3 compatible object storage.

This quickstart guide will show you how to install the MinIO client SDK, connect to MinIO, and provide a walkthrough for a simple file uploader. For a complete list of APIs and examples, please take a look at the Go Client API Reference.

This document assumes that you have a working Go development environment.

Initialize MinIO Client

MinIO client requires the following four parameters specified to connect to an Amazon S3 compatible object storage.

Parameter Description
endpoint URL to object storage service.
accessKeyID Access key is the user ID that uniquely identifies your account.
secretAccessKey Secret key is the password to your account.
secure Set this value to 'true' to enable secure (HTTPS) access. 
package main

import (
	"github.com/minio/minio-go/v6"
	"log"
)

func main() {
	endpoint := "play.min.io"
	accessKeyID := "Q3AM3UQ867SPQQA43P2F"
	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
	useSSL := true

	// Initialize minio client object.
	minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
	if err != nil {
		log.Fatalln(err)
	}

	log.Printf("%#v\n", minioClient) // minioClient is now setup
}

Quick Start Example - File Uploader

This example program connects to an object storage server, creates a bucket and uploads a file to the bucket.

We will use the MinIO server running at https://play.min.io in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.

	// Initialize minio client object.
	minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)

		log.Fatalln(err)
	}

	// Make a new bucket called mymusic.

		// Check to see if we already own this bucket (which happens if you run this twice)
		exists, errBucketExists := minioClient.BucketExists(bucketName)
		if errBucketExists == nil && exists {
			log.Printf("We already own %s\n", bucketName)
		} else {
			log.Fatalln(err)
		}
	} else {
		log.Printf("Successfully created %s\n", bucketName)
	}

	// Upload the zip file
	objectName := "golden-oldies.zip"
	filePath := "/tmp/golden-oldies.zip"
	contentType := "application/zip"

	// Upload the zip file with FPutObject
	n, err := minioClient.FPutObject(bucketName, objectName, filePath, minio.PutObjectOptions{ContentType:contentType})

ListObjectsV2WithMetadata lists all objects matching the objectPrefix from the specified bucket. If recursion is enabled it would list all subdirectories and all its contents. This call adds UserMetadata information as well for each object.

Your input parameters are just bucketName, objectPrefix, recursive and a done channel for pro-actively closing the internal go routine. If you enable recursive as 'true' this function will return back all the objects in a given bucket name and object prefix. 

api := client.New(....)
// Create a done channel.
doneCh := make(chan struct{})
defer close(doneCh)
// Recursively list all objects in 'mytestbucket'
recursive := true
// Add metadata
metadata := true
for message := range api.ListObjectsV2WithMetadata("mytestbucket", "starthere", recursive, doneCh) {
    fmt.Println(message)
