I am trying to connect my local MinIO instance running in docker. I have written a simple Go program to do the work. See following:
package main
import (
"bytes"
"context"
"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"
"log"
)
func main() {
endpoint := "localhost:9000"
accessKeyID := "1mVyDeEcrRU7qQ7h"
secretAccessKey := "vNi9SNfcHNxfRDETSvkeFLO210mzu7ee"
useSSL := false
awsSession := session.Must(session.NewSession(&aws.Config{
Region: aws.String("ap-south-1"),
Credentials: credentials.NewStaticCredentialsFromCreds(credentials.Value{
AccessKeyID: accessKeyID,
SecretAccessKey: secretAccessKey,
SessionToken: "",
}),
Endpoint: aws.String(endpoint),
DisableSSL: aws.Bool(!useSSL),
}))
ctx := context.Background()
file, err := downloadFileFromS3(ctx, awsSession, "mybucket", "data.txt")
if err != nil {
log.Fatal(err)
}
reader := bytes.NewReader(file)
println(reader)
}
func downloadFileFromS3(ctx context.Context, sess *session.Session, bucketName string, fileName string) ([]byte, error) {
downloader := s3manager.NewDownloader(sess)
buff := &aws.WriteAtBuffer{}
_, err := downloader.DownloadWithContext(ctx, buff,
&s3.GetObjectInput{
Bucket: aws.String(bucketName),
Key: aws.String(fileName),
})
if err != nil {
return nil, err
}
return buff.Bytes(), nil
}
But this fails to do the job. Check error below:
GOROOT=/usr/local/go #gosetup
GOPATH=/Users/kuldeep/go #gosetup
/usr/local/go/bin/go build -o /private/var/folders/29/zkqqp9_d0fscymp5ph4rscl40000gp/T/GoLand/___2go_build_minio_client_example minio-client-example #gosetup

What should I do to make it work?
