2019-11-22 13:57:56 +00:00
The MinIO Go Client SDK provides simple APIs to access any Amazon S3 compatible object storage.
2017-07-23 12:24:45 +00:00
2019-11-22 13:57:56 +00:00
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://docs.min.io/docs/golang-client-api-reference ).
2017-07-23 12:24:45 +00:00
2019-11-22 13:57:56 +00:00
This document assumes that you have a working [Go development environment ](https://golang.org/doc/install ).
2017-07-23 12:24:45 +00:00
## Download from Github
```sh
2019-11-22 13:57:56 +00:00
GO111MODULE=on go get github.com/minio/minio-go/v6
2017-07-23 12:24:45 +00:00
```
2019-11-22 13:57:56 +00:00
## Initialize MinIO Client
MinIO client requires the following four parameters specified to connect to an Amazon S3 compatible object storage.
2017-07-23 12:24:45 +00:00
2018-09-25 12:43:32 +00:00
| Parameter | Description|
2017-07-23 12:24:45 +00:00
| :--- | :--- |
2018-09-25 12:43:32 +00:00
| endpoint | URL to object storage service. |
2017-07-23 12:24:45 +00:00
| 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

if err != nil {

}
2017-09-13 12:09:48 +00:00
log.Printf("%#v\n", minioClient) // minioClient is now setup

}
2017-07-23 12:24:45 +00:00
```
## Quick Start Example - File Uploader
This example program connects to an object storage server, creates a bucket and uploads a file to the bucket.
2019-11-22 13:57:56 +00:00
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.
