                get size of layers of docker image. Inspired by this post(https://ops.tips/blog/inspecting-docker-image-without-pull/).

          # amount of arguments (image_name)
        

        

          
          # and then performs the main workflow:
        

        

          
          #       1.      retrieve the image digest
        

        

          
          #       2.      retrieve the layer info of image
