重启Ubuntu 16.05后无法启动docker

我试图在系统重启后在Ubuntu 16.04上运行docker。 我为它创build了服务“/etc/systemd/system/openvpnBOX.service”：

[Unit] Description=Openvpn Docker [Service] User=root ExecStart=/etc/init/openvpn.conf [Install] WantedBy=multi-user.target Alias=openvpnBOX.service 

openvpn.conf：

 #!/bin/bash exec docker run --volumes-from ovpn-data --rm -p 1194:1194/udp --cap- add=NET_ADMIN kylemanna/openvpn 

当我运行此服务“sudo服务openvpnBOX启动我看到该服务运行，但是当我重新启动我的系统，重新启动后，我看到该服务无法启动：

 "sudo service openvpnBOX status" ● openvpnBOX.service - Openvpn Docker Loaded: loaded (/etc/systemd/system/openvpnBOX.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sun 2017-10-01 21:35:48 SST; 2min 51s ago Process: 1771 ExecStart=/etc/init/openvpn.conf (code=exited, status=1/FAILURE) Main PID: 1771 (code=exited, status=1/FAILURE) Oct 01 21:35:48 systemd[1]: openvpnBOX.service: Main process exited, code=exited, status=1/FAILURE Oct 01 21:35:48 systemd[1]: openvpnBOX.service: Unit entered failed state.

Oct 01 21:35:48 systemd[1]: Failed to start Openvpn Docker. 

我可以使用"sudo docker run --restart=always --volumes-from ovpn-data -p 1194:1194/udp --cap-add=NET_ADMIN kylemanna/openvpn"但是这并不能解决我的问题，因为我会就像明白为什么我的服务不能在重新启动后工作。

任何想法？
