Makefile

[digitallysavvy]

Updated Dockerfile

• to support CORS_ALLOW_ORIGIN as a --build-arg
• to use SERVER_PORT as the port exposed (previously was always set to 8080)

Added Makefile to simplify the build process.

• Issue: The build process is a bit complex/confusing with setting .env for test the server with Go, to passing --build-arg for each environment variable.
• Solution: Use make to streamline the process. The Makefile simplifies the build and run process by reducing them to a single command. The Makefile uses the .env file to add the list of --build-arg's to the docker build command and executes the docker run command after the build is completed. To avoid unnecessary rebuilds of the token server, the Makefile sets a build_marker target to watch the Dockerfile, .go source code, and .env file. This enables a single command to build and run the container that only rebuilds as needed.
