本文主要是介绍Dockerfile配置——Ubuntu、Alpine，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

Ubuntu

FROM ubuntu:18.04

RUN cp /etc/apt/sources.list /etc/apt/sources.list.bak \
    && echo "" > /etc/apt/sources.list \
    && echo "deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse" >> /etc/apt/sources.list \
    && echo "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse" >> /etc/apt/sources.list \
    && apt-get update \

Alpine

FROM alpine:3.10

# alpine uses 'musl libc' rather than 'gnu libc', /lib64/ doesn't exist, it can be used by a soft link.
RUN mkdir /lib64 \
    && ln -s /lib/libc.musl-x86_64.so.1 /lib64/ld-linux-x86-64.so.2 \
    && ln -s /lib/libc.musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2 \
# apk mirror
    && sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories \
