Cuando reinicio mi host, quiero que mi motor acoplable se inicie en el arranque.

es posible? ¿Alguien puede señalarme en la dirección correcta?

Mi sistema operativo es RHEL 7.3 y mi campo /usr/lib/systemd/system/docker.service se ve así:

 [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network.target firewalld.service [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity Restart=always TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process [Install] WantedBy=multi-user.target
