Linux docker离线部署

1. Docker下载
Docker下载地址：https://mirrors.dahuatech.com/docker-ce/。本文下载当前最新版本，链接如下：https://mirrors.dahuatech.com/docker-ce/linux/static/stable/aarch64/docker-27.4.0.tgz。
2. 安装Docker
将压缩包上传到服务器上之后解压，命令如下：

tar –zxvf docker-27.4.0.tgz

完成后将文件复制到/usr/bin目录中，命令如下：

cp –rf docker/* /usr/bin/

然后就可以使用docker –v之类的命令了，因为没有开启守护进程，所以需要编写docker.service文件，命令如下：

vim /etc/systemd/system/docker.service

添加内容如下：

[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 unix:///var/run/docker.sock --selinux-enabled=false --default-ulimit nofile=65536:65536
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

添加执行权限并启动docker服务：

chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload
systemctl start docker

然后执行docker –v就可以开看到dockers版本了，运行docker ps就可以看到docker已经运行成功。
