Subject: [PATCH] fixed bug in entrypoint.sh

* use "hostname -I" instead of "hostname -i", as no DNS resolution is
  required

* "hostname -I" might return multiple IPs (as space delimited string).
  Use the first one ("best effort") per default. In case a different IP
  should be used for the swagger UI API resource, the "SWAGGER_IP" env
  variable must be set in the docker-compose.yml.

see #230
