Docker

1. 下载 docker 安装包

   服务器支持访问互联网

   wget http://pdpublic.mingdao.com/private-deployment/offline/common/docker-27.3.1.tgz

   服务器不支持访问互联网

   # docker 安装包文件下载链接，下载完成后上传到部署服务器
   http://pdpublic.mingdao.com/private-deployment/offline/common/docker-27.3.1.tgz

2. 解压，并将文件移动到二进制文件目录

   tar -zxvf docker-27.3.1.tgz

   mv -f docker/* /usr/local/bin/

3. 创建 docker 配置文件

   默认 docker 数据目录在 /data/docker，如果需要修改默认数据目录，请修改 daemon.json 配置文件中 data-root 的值

   mkdir -p  /etc/docker/

   cat > /etc/docker/daemon.json <<EOF
   {
     "registry-mirrors": ["https://uvlkeb6d.mirror.aliyuncs.com"],
     "data-root": "/data/docker",
     "max-concurrent-downloads": 10,
     "exec-opts": ["native.cgroupdriver=cgroupfs"],
     "storage-driver": "overlay2",
     "default-address-pools":[{"base":"172.80.0.0/16","size":24}]
   }
   EOF

4. 配置 systemd 管理 docker

   cat > /etc/systemd/system/docker.service <<EOF
   [Unit]
   Description=Docker
   After=network-online.target
   Wants=network-online.target
   [Service]
   Type=notify
   ExecStart=/usr/local/bin/dockerd
   ExecReload=/bin/kill -s HUP \$MAINPID
   LimitNOFILE=102400
   LimitNPROC=infinity
   LimitCORE=0
   TimeoutStartSec=0
   Delegate=yes
   KillMode=process
   Restart=on-failure
   StartLimitBurst=3
   StartLimitInterval=60s
   [Install]
   WantedBy=multi-user.target
   EOF

5. 启动 docker

   systemctl daemon-reload && systemctl start docker && systemctl enable docker
