# MinIO Go Client SDK for Amazon S3 Compatible Cloud Storage [](https://slack.min.io) [](https://sourcegraph.com/github.com/minio/minio-go?badge) [](https://github.com/minio/minio-go/blob/master/LICENSE)
The MinIO Go Client SDK provides simple APIs to access any Amazon S3 compatible object storage.
2022-11-07 13:20:43 +03:00
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 ](https://min.io/docs/minio/linux/developers/go/API.html ).
2022-07-03 13:08:30 +03:00
This document assumes that you have a working [Go development environment ](https://golang.org/doc/install ).
## Download from Github
```sh
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. |
```go
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 ](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.
### FileUploader.go
```go
package main
import (
"context"
"log"
"github.com/minio/minio-go/v7"
"github.com/minio/minio-go/v7/pkg/credentials"
)
func main() {
ctx := context.Background()
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)
}
// 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)
}
```
### Run FileUploader
```sh
go run file-uploader.go
2016/08/13 17:03:28 Successfully created mymusic
2016/08/13 17:03:40 Successfully uploaded golden-oldies.zip of size 16253413
mc ls play/mymusic/
[2016-05-27 16:02:16 PDT] 17MiB golden-oldies.zip
```
