docker环境和docker-compose一键安装脚本（内外网/离线安装）

docker下载地址

内网

文件目录结构如下

docker文件夹：docker解压后的安装包

daemon.json：docker容器全局配置文件，内容根据自己需求定，我的是限制日志大小，内容如下

{
  "registry-mirrors": ["https://kksxo8ii.mirror.aliyuncs.com"],
  "log-driver":"json-file",
  "log-opts":{"max-size":"100m"}
}

docker.service：docker服务配置文件，内容如下

[Unit]
Description=Docker Application Container Engine
Documentation=https://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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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
