Configuration error starting up docker development environment

[Daniel]

After clone the repository and execute the commands about docker-compose mentioned in the documentation, an error is raised:

/usr/local/lib/python3.7/site-packages/whitenoise/base.py:115: UserWarning: No directory at: /code/assets/static/

This seems to happen because of the configuration in docker-compose.yml is pointing to djangosnippets.settings.production. To launch in development this should be djangosnippets.settings.development.

It would be a good idea to make an environment file (.env) to externalize this values and configure it without touch source code and add this part to the documentation.

I usually put the following settings in the environment file.

SECRET_KEY
DEBUG
ALLOWED_HOSTS


ENGINE
DB_NAME
POSTGRES_USER
POSTGRES_PASSWORD
DB_HOST
DB_PORT

There are more project specific env variables for elasticsearch and redis as well.
