【docker】容器优化：一行命令换源

原理：

根据清华源提供的Ubuntu 软件仓库进行sources.list替换

ubuntu | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

1、换源

echo "">/etc/apt/sources.list \
    && echo "# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释">>/etc/apt/sources.list \
    && echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "deb http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# deb-src http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# 预发布软件源，不建议启用">>/etc/apt/sources.list \
    && echo "# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse">>/etc/apt/sources.list \
    && echo "# # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse">>/etc/apt/sources.list

2、更新软件列表

apt-get clean && apt-get update
