instruction: Create a Dockerfile for fundamentals
output: ```dockerfile
  from your Compose file; it includes all of
  your services containing a build configuration. To build this group of services
  with Bake, run:
  
  $ docker buildx bake
  Customize the build groupStart by redefining the default build group that Bake executes. The current
  default group includes a seed target â a Compose service used solely to
  populate the database with mock data. Since this target doesn't produce a
  production image, it doesnât need to be included in the build group.To customize the build configuration that Bake uses, create a new file at the
  root of the repository, alongside your compose.yaml file, named
  docker-bake.hcl.
  
  $ touch docker-bake.hcl
  Open the Bake file and add the following configuration:docker-bake.hcl
  
  group "default" {
   targets = ["vote", "result", "worker"]
  }Save the file and print your Bake definition again.
  
  $ docker buildx bake --print
  The JSON output shows that the default group only includes the targets you
  care about.
