实验环境 操作系统：Ubuntu 18.04.4 LTS
LAN IP ：192.168.3.22
Docker 是现代软件开发和DevOps持续集成和部署管道中不可或缺的一部分,大部分公司都使用容器化技术，降低服务器成本。
安装必要的系统资源库 root@linuxcool:~# apt-get updateroot@linuxcool:~# apt-get -y install apt-transport-https ca-certificates curl software-properties-common 安装GPG证书 root@linuxcool:~# curl -fsSL https://mirrors.nwafu.edu.cn/docker-ce/linux/ubuntu/gpg | apt-key add - Docker服务器在国外，如果使用docker.io来安装docker会非常慢，有时候还会超时断开导致无法安装成功；所以，我这里使用的是国内“西北农林科技大学网络与教育技术中心”镜像加速，国内还有很多镜像加速站点，比如：阿里云、腾讯云、网易、清华大学等，
更新系统并安装Docker-CE root@linuxcool:~# apt-get -y updateroot@linuxcool:~# apt-get -y install docker-ce 通过以上命令安装的是docker最新版本，如果要安装docker，请继续阅读下文，
