Docker

安装 Docker

1. 下载 Docker 安装包

   服务器支持访问互联网

   wget https://pdpublic.mingdao.com/private-deployment/offline/common/docker-29.9.3.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
   https://pdpublic.mingdao.com/private-deployment/offline/common/docker-29.9.3.tgz

2. 解压 Docker 安装包

   tar -zxvf docker-29.9.3.tgz

3. 将文件移动到二进制文件目录

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

4. 创建 Docker 配置目录

   mkdir -p  /etc/docker/

5. 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

   cat > /etc/docker/daemon.json <<EOF
   {
     "registry-mirrors": ["https://uvlkeb6d.mirror.aliyuncs.com"],
     "data-root": "/data/docker",
     "max-concurrent-downloads": 10,
     "default-ulimits": {
       "nofile": {
         "Name": "nofile",
         "Soft": 102400,
         "Hard": 102400
       }
     },
     "exec-opts": ["native.cgroupdriver=cgroupfs"],
     "storage-driver": "overlay2",
     "default-address-pools":[{"base":"172.80.0.0/16","size":24}],
     "log-driver": "json-file",
     "log-opts": {
     "max-size": "1g",
     "max-file": "5"
     }
   }
   EOF

6. 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

7. 启动 Docker

   systemctl daemon-reload
   systemctl start docker
   systemctl enable docker

安装 Docker Compose

1. 下载 Docker Compose

   服务器支持访问互联网

   wget https://pdpublic.mingdao.com/private-deployment/offline/common/docker-compose-linux-x86_64

   服务器不支持访问互联网

   # 下载完成后上传至部署服务器
   https://pdpublic.mingdao.com/private-deployment/offline/common/docker-compose-linux-x86_64

2. 创建 Docker CLI 插件目录

   mkdir -p /usr/local/lib/docker/cli-plugins

3. 将文件移动到插件目录

   mv docker-compose-linux-x86_64 /usr/local/lib/docker/cli-plugins/docker-compose

4. 设置执行权限

   chmod +x /usr/local/lib/docker/cli-plugins/docker-compose

5. 创建兼容旧版 docker-compose 命令的软链接

   ln -s /usr/local/lib/docker/cli-plugins/docker-compose /usr/local/bin/docker-compose

6. 验证安装

   docker compose version
   docker-compose version
