How to set permission of all files in a bucket as public on every upload.

i’m using https://github.com/minio/minio-go, here is what i did.

	endpoint := "sgp1.digitaloceanspaces.com"
	accessKeyID := "access-key"
	secretAccessKey := "secret-access-key"
	useSSL := true

	// Initialize minio client object.
	minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
	if err != nil {
		log.Fatalln(err)
	}

	// Upload the file
	bucketName := "indonesia"
	newImageName := uuid.NewV4()
	objectName := "indonesia.jpg"
        fileObject := bytes.NewReader(body)
	contentLength := r.ContentLength
	contentType := r.Header.Get("Content-type")
	cacheControl := "max-age=31536000"
       // make it public
	userMetaData := map[string]string{"x-amz-acl": "public-read"}

	n, err := minioClient.PutObject(bucketName, objectName, fileObject, contentLength, minio.PutObjectOptions{ContentType: contentType, CacheControl: cacheControl, UserMetadata: userMetaData})
	if err != nil {
		log.Fatalln(err)
	}

You can take a look at my Github repo to get a easy solution:

You have to specify ACL as public-read in the request headers:

‘x-amz-acl’: ‘public-read’
