环境
centos7

装置 docker
移除旧版本 docker
[root@chaols ~]# sudo yum remove docker \

              docker-client \
              docker-client-latest \
              docker-common \
              docker-latest \
              docker-latest-logrotate \
              docker-logrotate \
              docker-engine

装置 yum-utils 包并设置稳固存储库
[root@chaols ~]# yum install -y yum-utils
装置 docker
[root@chaols ~]# yum install docker-ce docker-ce-cli containerd.io
启动 docker
[root@chaols ~]# systemctl start docker
查看 docker 镜像
刚刚装置 docker 是没有镜像的

[root@chaols ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
部署 nginx
下载 nginx 镜像
[root@chaols ~]# docker pull nginx

创立 nginx 虚拟机
run 运行 -it 交互模式 –name 指定名字 -p 宿主机：docker 虚拟机 nginx 镜像名字 /bin/bash 启动容器后启动 bash

[root@chaols ~]# docker run -it –name chao.nginx -p 8080:80 nginx /bin/bash
