I am trying to start docker on centos7.1 using the instructions from https://docs.docker.com/installation/centos/. After installing, whenever I try to start the daemon (sudo service docker start) with docker versions 1.8.0-1.8.2 (the latest version), it doesn’t start properly, and I get this error when looking into systemctl:

systemd: docker.service operation timed out. Terminating.
systemd: Failed to start Docker Application Container Engine.
systemd: Unit docker.service entered failed state.
When I grabbed an older version of docker (1.7.1) it installed and started with no problems. Is there something I’m missing when trying to install the most recent docker engine to centos7.1? Or is there a compatibility issue that anyone has seen?
My kernel: 3.10.0-229.el7.x86_64
My Os: CentOS Linux release 7.1.1503 (Core)
