docker-compose -v
docker-compose version 1.8.0, build unknown

and with 1.20.0 everything is OK

@epcim pls write commit body properly, why we need it? and have u checked tests? its already failed
IMO we can't change depend-software versions without important reason, coz there are a lot of dependencies and also need to check backport compatibility
