Simple NodeJS app to poll a RethinkDB cluster for issues
Save your RethinkDB auth key as an environment variable called AUTH_KEY
Run the container by linking it to one of your servers in the RethinkDB cluster:
docker run -d --link [name-of-your-rethinkdb-container]:db -p 8080:8080 -e "AUTH_KEY=[your-auth-key]" rethinkdb-status
