You may need to add yourself to the docker group thus:

$ sudo adduser $LOGNAME docker $ exec newgrp docker # or log out, log back in

Edit db.env file

$ cp db.env.example db.env $ $EDITOR db.env

Set up environment

$ docker-compose up

Test

$ env-vars ()
{
    awk -F= '{printf "'%s=%s' ", $1, $2}' config/test_api.env
}
$ docker exec -it metrics_api env $(env-vars) nosetests -v
