docker离线部署

1、目的

在可以连接互联网的情况下可以在线安装Docker《Linux下Docker安装部署》如果遇到内网服务器就没有办法进行在线安装那么需要使用离线安装的方法。

2、下载安装包

创建工作文件夹

mkdir /opt/docker

docker安装包下载地址https://download.docker.com/linux/static/stable/x86_64/ 进入下载地址下载相应的版本比如20.10.9将下载好的文件放到/opt/docker目录下

3、创建系统配置文件

创建文件

vim /opt/docker/docker.service

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
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

4、创建安装脚本

vim /opt/docker/install.sh

内容如下

#!/bin/sh
echo '解压tar包...'
tar -xvf $1
echo '将docker目录移到/usr/bin目录下...'
cp docker/* /usr/bin/
echo '将docker.service 移到/etc/systemd/system/ 目录...'
cp docker.service /etc/systemd/system/
echo '添加文件权限...'
chmod +x /etc/systemd/system/docker.service
echo '重新加载配置文件...'
systemctl daemon-reload
echo '启动docker...'
systemctl start docker
echo '设置开机自启...'
systemctl enable docker.service
echo 'docker安装成功...'
docker -v

5、创建卸载脚本

vim /opt/docker/uninstall.sh

内容如下

#!/bin/sh
echo '删除docker.service...'
rm -f /etc/systemd/system/docker.service
echo '删除docker文件...'
rm -rf /usr/bin/docker*
echo '重新加载配置文件'
systemctl daemon-reload
echo '卸载成功...'

6、安装

1、安装目录结构如下

2、执行安装脚本

sh install.sh docker-20.10.9.tgz

7、配置国内源

编辑daemon.josn

vim /etc/docker/daemon.json

配置国内源地址

{ 
   
 "registry-mirrors" : [
   "https://mirror.ccs.tencentyun.com",
   "http://registry.docker-cn.com",
   "http://docker.mirrors.ustc.edu.cn",
   "http://hub-mirror.c.163.com"
 ],
 "insecure-registries" : [
   "registry.docker-cn.com",
   "docker.mirrors.ustc.edu.cn"
 ],
 "debug" : true,
 "experimental" : true
}

重启docker

systemctl restart docker.service
