##
## A service stack for the Dug semantic search framework.
##
## NOTE: .env contains *_HOST variables that are set to internal docker service
##       names. These names resolve to an IP address *within* the docker machine
##       CIDR block, not your local development machine.
##
## NOTE: To connect to a dug service running in docker machine, from your local
##       development machine, you will need to follow the steps in the Quickstart
##       section of the README.md and set/export the env vars with special attention
##       paid to the env vars: ELASTIC_API_HOST, and REDIS_HOST.
