// This file defines the build configuration for the Docker images using Docker Bake.
// Docker Bake is a tool that allows building multiple Docker images in parallel,
// based on a declarative configuration file.
//
// For more information on Docker Bake, see the official documentation:
// https://docs.docker.com/build/bake/reference/
//
// == Usage ==
//
// To build the images, you can use the `docker buildx bake` command.
//
// Build the default target (amd64 for all distros):
// docker buildx bake
//
// Build all targets (amd64 and arm64):
// docker buildx bake all
//
// Build a specific target:
// docker buildx bake amd64
//
// =================================================================================================
