Hello from Docker! (运行成功) This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash

安装一个centos镜像学习
docker pull centos Using default tag: latest latest: Pulling from library/centos a1d0c7532777: Pull complete Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177 Status: Downloaded newer image for centos:latest docker.io/library/centos:latest
docker run [可选参数] image
参数说明
–name=”name” 给容器起名字
-d 后台方式运行
-it 使用交互方式运行，进入容器查看内容
-P 指定容器的端口（大写）
-p 主机端口：容器端口 映射
-p 容器端口
-p 随机端口（小写）
docker run -it centos /bin/bash 启动容器并用bash交互,可见内部也还是一个独立的centos系统
