In the Dockerfile, there are two stages. The first stage (build) builds the application using the specified Go version, and the second stage (scratch) creates a minimal image without any operating system or additional layers. The binary file built in the first stage is copied into the second stage. This approach helps reduce the overall file size of the Docker image.
