# 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


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.




# Uncomment TasksMax if your systemd version supports it.

# Only systemd 226 and above support this version.



# set delegate yes so that systemd does not reset the cgroups of docker containers


# kill only the docker process, not all processes in the cgroup


# restart the docker process if it exits prematurely
