系统环境：龙芯3A3000+Loongnix1.0

1. 制作debian最小系统
   # debootstrap --arch mips64el buster debian10_mips64el http://mirrors.ustc.edu.cn/debian

2. 导入docker

### 此处用loongsongd 是为了上传到hub.docker.com。 loongsongd 是在hub.docker 上注册的用户名 
# tar -C debian10_mips64el/ -c . | docker import - loongsongd/debian:v10
sha256:89b502980b393daf52301470284750d999384fc2d982f61274a12b4fc9dfbd5e

3. 查看与启动镜像

# docker image ls
