# 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 straightforward APIs to access any Amazon S3 compatible object storage.
|
|
|
|
This Quickstart Guide covers how to install the MinIO client SDK, connect to MinIO, and create a sample file uploader.
|
|
For a complete list of APIs and examples, see the [godoc documentation](https://pkg.go.dev/github.com/minio/minio-go/v7) or [Go Client API Reference](https://min.io/docs/minio/linux/developers/go/API.html).
|
|
|
|
These examples presume a working [Go development environment](https://golang.org/doc/install) and the [MinIO `mc` command line tool](https://min.io/docs/minio/linux/reference/minio-mc.html).
|
|
|
|
## Download from Github
|
|
|
|
From your project directory:
|
|
|
|
```sh
|
|
go get github.com/minio/minio-go/v7
|
|
```
|
|
|
|
## Initialize a MinIO Client Object
|
|
|
|
The MinIO client requires the following parameters 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
|
|
}
|
|
```
|
|
|
|
## Example - File Uploader
|
|
|
|
This sample code connects to an object storage server, creates a bucket, and uploads a file to the bucket.
|
|
It uses the MinIO `play` server, a public MinIO cluster located at [https://play.min.io](https://play.min.io).
|
|
|
|
The `play` server runs the latest stable version of MinIO and may be used for testing and development.
|
|
The access credentials shown in this example are open to the public and all data uploaded to `play` should be considered public and non-protected.
|
|
|
|
### FileUploader.go
|
|
|
|
This example does the following:
|
|
|
|
- Connects to the MinIO `play` server using the provided credentials.
|
|
- Creates a bucket named `testbucket`.
|
|
- Uploads a file named `testdata` from `/tmp`.
|
|
- Verifies the file was created using `mc ls`.
|
|
|
|
```go
|
|
// FileUploader.go MinIO example
|
|
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 testbucket.
|
|
bucketName := "testbucket"
|
|
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 test file
|
|
// Change the value of filePath if the file is in another location
|
|
objectName := "testdata"
|
|
filePath := "/tmp/testdata"
|
|
contentType := "application/octet-stream"
|
|
|
|
// Upload the test 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)
|
|
}
|
|
```
|
|
|
|
**1. Create a test file containing data:**
|
|
|
|
You can do this with `dd` on Linux or macOS systems:
|
|
|
|
```sh
|
|
dd if=/dev/urandom of=/tmp/testdata bs=2048 count=10
|
|
```
|
|
|
|
or `fsutil` on Windows:
|
|
|
|
```sh
|
|
fsutil file createnew "C:\Users\<username>\Desktop\sample.txt" 20480
|
|
```
|
|
|
|
**2. Run FileUploader with the following commands:**
|
|
|
|
```sh
|
|
go mod init example/FileUploader
|
|
go get github.com/minio/minio-go/v7
|
|
go get github.com/minio/minio-go/v7/pkg/credentials
|
|
go run FileUploader.go
|
|
```
|
|
|
|
The output resembles the following:
|
|
|
|
```sh
|
|
2023/11/01 14:27:55 Successfully created testbucket
|
|
2023/11/01 14:27:55 Successfully uploaded testdata of size 20480
|
|
```
|
|
|
|
**3. Verify the Uploaded File With `mc ls`:**
|
|
|
|
```sh
|
|
mc ls play/testbucket
|
|
[2023-11-01 14:27:55 UTC] 20KiB STANDARD TestDataFile
|
|
```
