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

I am accessing DigitalOcean Spaces with the help of AWS SDK. I am able to connect and upload file to the Spaces bucket. I'm uploading a directory with recursive directories and files using 'TransferManager.uploadDirectory()' method. Is there a way to set permission as public as a part of uploading instead of iterating and setting individual object permission in another API call.
But I want to set permission of all files which I'm uploading as 'public'. By default it is 'private'.

I tried using AWS bucket policy .. but it is not supporting in DO Spaces.
Also everytime I upload files to that particular bucket, I want all those files to be public.

Kindly help me with this. I'm searching for a generic solution. I'm not getting any way around.

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

'x-amz-acl': 'public-read'

I am with same problem here. anyone on dg could help on this?

Did you know how to make all the bucket public

i'm using, here is what i did.

    endpoint := ""
    accessKeyID := "access-key"
    secretAccessKey := "secret-access-key"
    useSSL := true

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

    // 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 {
