自己动手做一个docker base images

创建一个文件hello.c

#include<stdio.h>
int main()
{
printf("hello world\n");
}

[root@localhost ~]# gcc -static hello.c -o hello  　　　　 --编译源代码
[root@localhost ~]# ls
anaconda-ks.cfg hello.c  模板 图片 下载 桌面
hello initial-setup-ks.cfg start.sh 公共 视频 文档 音乐
[root@localhost ~]# vim dockerfile           ---手写一个dockerfile
[root@localhost ~]# docker build -t mydocker .            --打镜像
