# Start DB
echo "---> Starting Mongo"
DB_ID=$(docker run -d -P docker-registry.intranet/mongo:2.4)

echo "Found Mongo at port $DB_PORT"

if [[ -n $DOCKER_HOST ]]; then
  DB_IP=$(echo $DOCKER_HOST|sed -e 's|tcp://||' -e 's|:[0-9]\+||')
else

echo "Waiting for Mongo at $DB_IP:$DB_PORT to begin listening"
until nc -z $DB_IP $DB_PORT; do
  sleep 0.5

echo "Done!"
