* feat: vendor minio client * feat: introduce storage package with s3 support * feat: serve s3 files directly this saves a lot of bandwith as the files are fetched from the object store directly * fix: use explicit local storage in tests * feat: integrate s3 storage with the main server * fix: add s3 config to cli tests * docs: explicitly set values in example config also adds license header to the storage package * fix: use better http status code on s3 redirect HTTP 302 Found is the best fit, as it signifies that the resource requested was found but not under its presumed URL 307/TemporaryRedirect would mean that this resource is usually located here, not in this case 303/SeeOther indicates that the redirection does not link to the requested resource but to another page * refactor: use context in storage driver interface

# 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.
|
|
|
|
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).
|
|
|
|
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
|
|
|
|

|

|
|
useSSL := true
|
|
|
|
// Initialize minio client object.
|
|
minioClient, err := minio.New(endpoint, &minio.Options{
|

|
|
})
|
|

// Make a new bucket called mymusic.
|
|

|
|
|
|
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)
|
|
}
|
|
```
