 # 前几步因为针对本实验依赖不全的原因问题百出，所以放弃了，还是ubuntu20.04官方镜像源对于MIT6.S081所需依赖最全面
 # 1.备份源列表
 # RUN cp /etc/apt/sources.list /etc/apt/sources.backup.list
 # 2.把本目录下的sources.list中的镜像源添加到Docker中，下载速度起飞
 # COPY sources.list /etc/apt/sources.list
 # 3.更新源
 # RUN apt-get update 
 ​
 # 创建一个mit6s081的用户和其home目录
 RUN useradd -m mit6s081 && \
     echo "root ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers && \
     echo "mit6s081 ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

 # MIT6.S081 Lab所用依赖
 # 1.安装RISC-V交叉编译工具和一些其他的常用工具
 RUN apt-get update && \
     apt-get install -y sudo locales git wget vim build-essential gdb-multiarch qemu-system-misc gcc-riscv64-linux-gnu binutils-riscv64-linux-gnu libpixman-1-dev gcc-riscv64-unknown-elf libglib2.0-dev pkg-config
 # 2.安装QEMU和配置QEMU
 RUN wget https://download.qemu.org/qemu-5.1.0.tar.xz 
 RUN tar xf qemu-5.1.0.tar.xz 
 RUN cd qemu-5.1.0 && \
     ./configure --disable-kvm --disable-werror --prefix=/usr/local --target-list=riscv64-softmmu && \
     make && \
     make install
 ​
 # 下载code-server并安装
 RUN apt-get install -y aria2 && \
     aria2c https://github.com.cnpmjs.org/cdr/code-server/releases/download/v3.12.0/code-server_3.12.0_${arch_name}.deb && \
     dpkg -i code-server_3.12.0_${arch_name}.deb
