There are two options for connecting Go applications to MinIO.
Connecting to MinIO with the AWS SDK
First, install the AWS SDK packages for Go:
go get github.com/aws/aws-sdk-go-v2
go get github.com/aws/aws-sdk-go-v2/config
Below is an example of how to connect to MinIO from Go using the AWS SDK:
package main
import (
"fmt"
"os"
"strings"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/credentials"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/aws/aws-sdk-go/service/s3"
"github.com/aws/aws-sdk-go/service/s3/s3manager"
)
func main() {
bucket := aws.String("newbucket")
key := aws.String("testobject")
// Configure to use the MinIO server
s3Config := &aws.Config{
Credentials: credentials.NewStaticCredentials("YOUR_ACCESS_KEY", "YOUR_SECRET_KEY", ""),
Endpoint: aws.String("https://<XXXXXX>.stackhero-network.com"),
Region: aws.String("us-east-1"),
DisableSSL: aws.Bool(false),
S3ForcePathStyle: aws.Bool(true),
}
newSession := session.New(s3Config)
s3Client := s3.New(newSession)
cparams := &s3.CreateBucketInput{
Bucket: bucket,
}
// Create a new bucket
_, err := s3Client.CreateBucket(cparams)
if err != nil {
fmt.Println(err.Error())
return
}
// Upload a new object with the string "Hello from MinIO!"
_, err = s3Client.PutObject(&s3.PutObjectInput{
Body: strings.NewReader("Hello from MinIO!"),
Bucket: bucket,
Key: key,
})
if err != nil {
fmt.Printf("Failed to upload data to %s/%s, %s\n", *bucket, *key, err.Error())
return
}
fmt.Printf("Successfully created bucket %s and uploaded data with key %s\n", *bucket, *key)
// Retrieve our object and store it locally
file, err := os.Create("testobject_local")
if err != nil {
fmt.Println("Failed to create file", err)
return
}
defer file.Close()
downloader := s3manager.NewDownloader(newSession)
numBytes, err := downloader.Download(file,
&s3.GetObjectInput{
Bucket: bucket,
Key: key,
})
if err != nil {
fmt.Println("Failed to download file", err)
return
}
fmt.Println("Downloaded file", file.Name(), numBytes, "bytes")
}

Connecting to MinIO with the MinIO SDK
To use the MinIO SDK for Go, install the following package:
GO111MODULE=on go get github.com/minio/minio-go/v7
Below is an example showing how to connect to MinIO using the MinIO SDK for Go:
package main
import (
"log"
"github.com/minio/minio-go/v7"
"github.com/minio/minio-go/v7/pkg/credentials"
)
func main() {
endpoint := "<XXXXXX>.stackhero-network.com"
accessKeyID := "YOUR_ACCESS_KEY"
secretAccessKey := "YOUR_SECRET_KEY"
useSSL := true
// Initialize the MinIO client
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
}
For more information, please see the MinIO Go SDK documentation.
