[Unit]

Description=Docker Application Container Engine

Documentation=docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

[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 --selinux-enabled=false --insecure-registry=127.0.0.1

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

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

restart the docker process if it exits prematurely

Restart=on-failure

StartLimitBurst=3

StartLimitInterval=60s

[Install]

WantedBy=multi-user.target
