• Create ".env" file in the same directory as .env.example
• Copy everything from env.example
• Edit the .env file with appropriate values as needed, blank will be treated as empty value

  • .env variable is ignored by default

  • By default Dockerfile.dev is being used so that Dockerfile can be created based on CI/CD envieronments. So don't alter a lot of setups unless you know what you are doing.

• Open env.example and write up the new env var that is needed without the value at the bottom ex: keynameinenv=

• Edit the env vars in .env file enter the appropriate value ex: keynameinenv=valuewithoutquotes

• Edit docker compose file and in the service that would need that new config varible put it in this format

        services:
            servicename:
                environment:
                    - KEY_NAME=${keynameinenvfile}
  

• The KEY_NAME in docker-compose will directly be available in node's process.env.KEY_NAME

sudo ./init.sh
