制作符合自己要求的镜像（重点）
法一：从已有容器中更新镜像，并且提交这个镜像
更新 ubuntu成为自己需要的镜像
1 进入容器 docker run ubuntu
malijun@MaLiJun-Ubuntu:~/workdir/dockerpro/bitmexpro$ docker run -it ubuntu /bin/bash root@3a910bf167ab:/# ls bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var root@3a910bf167ab:/# cat /etc/issue Ubuntu 18.04 LTS \n \l
2 更新系统源 apt-get update

(3 安装python3.6 apt-get install python3.6)
3 退出容器 exit
root@86437e52b5f2:/# exit
exit
4 对更新了系统源的容器，保存为新的image
malijun@MaLiJun-Ubuntu:~/workdir/dockerpro/bitmexpro$ docker commit -m "has update" -a "mlj" 86437e52b5f2 mlj/ubuntu:18.04 sha256:ff7c022e2bb3d70f1f6a09be20f81ac2fab9a6b7b9784ab5e7f0835746f492cf

法二：使用dockerfile指令创建镜像
1 需要编写Dockerfile文件
2 使用docker build 命令构建镜像
