- default command should be start, rather than start:dev in the docker image
- added a multistage build
- fixed node-gyp error
- removed dev dependencies
- added a start:dotenv script to support a .env file in production (may be useful for
k8s later)
- updated Readme and generateEnv script to simplify the setup
- updated external network in docker-compose.yaml to match the test network
