 Certain configuration options can be adjusted by setting environment variables or by defining these variables in a `.env` file stored in the same directory as the `docker-compose.yml` file. These variables are:
 `APP_PORT`: port mapping for the web app server
 `CONTAINER_NAME`: name of the application container

 ### Example Configuration Files
 The following snippet shows an `instances.conf` file with 3 instances defined. Instance `test0001-_default` will use port `3001`, `test0002-_default` will use `3002`, etc.
