docker-compose exec is failing when reading from stdin:
$ echo "use mydb; show measurements;" | docker-compose exec influxdb influx

ValueError: file descriptor cannot be a negative integer (-1)
Using the -T flag gets rid of the problem, but it seems to suppress reading from stdin:
$ echo "use mydb; show measurements;" | docker-compose exec -T influxdb influx
(I need to kill that command, since it shows nothing and is not able to read from stdin)
This seems like a docker-compose bug, maybe I should file this?
$ docker-compose --version
docker-compose version 1.9.0, build 2585387
