Wrong alias in docker-compose.yml

[rekn64]

api seems unable to connect to the db. i think the problem is the wrong alias used in docker-compose.yml file

suggestion:
change
MONGODB_CONNECTION_STRING=mongodb://isp-db:27017/isp
to
MONGODB_CONNECTION_STRING=mongodb://db:27017/isp

and add the option

    links:
        - db

to the api service.

also change the environment in example.env to
MONGODB_CONNECTION_STRING=mongodb://db:27017/isp

furthermore:

example.env seems to miss the NODE_ENV enviroment

suggestion add to example.env
NODE_ENV=production

db connection
should be fixed in commit b929359

link
link is unnecessary, as within docker all services are reachable by service name by default. link just gives you the option to configure additional aliases.

node_env in example.env
not required, as we only test for NODE_ENV === "production", and it assumes development for anything else.
the example.env should mimic the development environment by default, and should be adapted by whoever is deploying, to fit the required env.
