version: '3.8'

# This is a reference for a standard deployment

# The following environment variables need to be set appropriately (in a .env file for example):

# NOTES_USER
# NOTES_PASSWORD
# POSTGRES_USER
# POSTGRES_PASSWORD
# POSTGRES_DB
# NOTES_FRONTEND_SERVER_NAME

# The backend uses the environment variable "NOTES_DB_HOST" when built standalone, it is set here
# NOTES_FRONTEND_SERVER_NAME is the NGINX configuration's server name for the frontend
# eg: localhost, your domain name or an IP
