Hello,
I think the docker service with Travis CI doesn't start properly, without the "Chain DOCKER" in iptables.
So, we can't start container with mapping port.
I added
sudo service docker restart ; sleep 10
and made minor change in build lifecyle.Someone has tested this solution and it seems to fix the problem : travis-ci/travis-ci#4778
