# 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

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
 +
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
 +
# to make them work for either version of systemd.
 +
StartLimitBurst=3
 +
 +
# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.

# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make

# this option work for either version of systemd.
 +
StartLimitInterval=60s
 +
 +
# Having non-zero Limit*s causes performance problems due to accounting overhead
 +
# in the kernel. We recommend using cgroups to do container-local accounting.

LimitCORE=infinity
 +
 +
# Comment TasksMax if your systemd version does not support it.

 +
 +
# 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
