The docker image doesn't load on system startup on Ubuntu 16.04 LTS with the command you provided :
$ docker run -d --name docker-hostmanager --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /etc/hosts:/hosts iamluc/docker-hostmanager
It worked flawlessly on Debian 8, though.
At the moment, I have to launch docker start docker-hostmanager manually.
