   It is because its the tar file in the reader.

   import("archive/tar")
   ....
   reader, _, err = CopyFromContainer(context.TODO(), containerId, path)
   if err != nil{
                   log.Println(err.Error())
   }
   tr := tar.NewReader(reader)
   for {
                   // hdr gives you the header of the tar file
                   hdr, err := tr.Next()
                   if err == io.EOF {
                           // end of tar archive
                           break
                   }
                   if err != nil {
                           log.Fatalln(err)
                   }
                   buf := new(bytes.Buffer)
                   buf.ReadFrom(tr)
                   
                   // You can use this wholeContent to create new file
                   wholeContent := buf.String()
                   
                   fmt.Println("Whole of the string of ", hdr.Name ," is ",wholeContent)
                   
   }
   

   This gives you the content, you can use to create files on your own. Look into https://golang.org/pkg/archive/tar/#pkg-examples
