# Minio Go Client SDK for Amazon S3 Compatible Cloud Storage [](https://slack.minio.io) [](https://sourcegraph.com/github.com/minio/minio-go?badge)
|
||
|
|
|
||
|
|
The Minio Go Client SDK provides simple APIs to access any Amazon S3 compatible object storage.
|
||
|
|
|
||
|
|
**Supported cloud storage providers:**
|
||
|
|
|
||
|
|
- AWS Signature Version 4
|
||
|
|
- Amazon S3
|
||
|
|
- Minio
|
||
|
|
|
||
|
|
- AWS Signature Version 2
|
||
|
|
- Google Cloud Storage (Compatibility Mode)
|
||
|
|
- Openstack Swift + Swift3 middleware
|
||
|
|
- Ceph Object Gateway
|
||
|
|
- Riak CS
|
||
|
|
|
||
|
|
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://docs.minio.io/docs/golang-client-api-reference).
|
||
|
|
|
||
|
|
This document assumes that you have a working [Go development environment](https://docs.minio.io/docs/how-to-install-golang).
|
||
|
|
|
||
|
|
## Download from Github
|
||
|
|
```sh
|
||
|
|
go get -u github.com/minio/minio-go
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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. |
|
||
|
|
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"github.com/minio/minio-go"
|
||
|
|
"log"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
endpoint := "play.minio.io:9000"
|
||
|
|
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.Println("%v", 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.minio.io:9000](https://play.minio.io:9000) in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.
