I am aware you are not asking me for this, but I am sharing my docker compose with you if that helps you get started. Rename the dotenv.txt file to .env and place it under the same directory as the docker-compose.yml file.
I am using linux as my main OS so not sure how the .env file plays along in windows but you will get the big picture from them files.
NOTE: I am using the enterprise version of netmaker and you will need a registration id/key that you can get from their main website.
