Docker离线安装

1. 安装目录

   mkdir /opt/docker && cd /opt/docker

2. 安装包下载

   yum -y install wget && wget https://download.docker.com/linux/static/stable/x86_64/docker-24.0.7.tgz
   注意：https://download.docker.com/linux/static/stable/x86_64 获取最新版本下载链接并替换(docker-xxx.tgz)

3. 安装包解压

   tar -xvf docker-24.0.7.tgz && cp docker/* /usr/bin/

4. 注册服务

   sudo tee /usr/lib/systemd/system/docker.service <<-'EOF'

   ExecReload=/bin/kill -s HUP $MAINPID

5.  镜像源配置

   sudo mkdir -p /etc/docker/
   sudo tee /etc/docker/daemon.json <<-'EOF'
   {
     "registry-mirrors": ["https://8q5nyauc.mirror.aliyuncs.com"]
   }
   EOF
   sudo systemctl daemon-reload
   sudo systemctl restart docker

6. 启动服务
