MinIO Go Client SDK for Amazon S3 Compatible Cloud Storage

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.

go get github.com/minio/minio-go/v7

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.
minio.Options	All the options such as credentials, custom transport etc.

package main

import (
    "log"

    "github.com/minio/minio-go/v7"
    "github.com/minio/minio-go/v7/pkg/credentials"
)

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

    // Initialize minio client object.
    minioClient, err := minio.New(endpoint, &minio.Options{
        Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
        Secure: useSSL,
    })
    if err != nil {
        log.Fatalln(err)
    }

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

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.

import (
    "context"

func main() {
    ctx := context.Background()

    accessKeyID := "Q3AM3UQ867SPQQA43P2F"
    secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"

    // Initialize minio client object.

        Secure: useSSL,
    })
    if err != nil {
        log.Fatalln(err)
    }

    // Make a new bucket called mymusic.
    bucketName := "mymusic"
    location := "us-east-1"

    err = minioClient.MakeBucket(ctx, bucketName, minio.MakeBucketOptions{Region: location})
    if err != nil {
        // Check to see if we already own this bucket (which happens if you run this twice)
        exists, errBucketExists := minioClient.BucketExists(ctx, 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
    info, err := minioClient.FPutObject(ctx, bucketName, objectName, filePath, minio.PutObjectOptions{ContentType: contentType})
    if err != nil {
        log.Fatalln(err)
    }

    log.Printf("Successfully uploaded %s of size %d\n", objectName, info.Size)
}
