1.设置静态IP，以centos为例

2.yum源管理

添加源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
查看源
yum repolist all
启用源
yum-config-manager --enable
禁用源
yum-config-manager --disable

3.python设置软链接之后导致yum出错

vi /usr/bin/yum

!/usr/bin/python2.7

3.Dockerfile打包ubuntu系统，调整仓库

基于ubuntu镜像

FROM ubuntu:latest
ENV TZ='Asia/Shanghai'
ENV INDEX=/licenseCheck 
COPY . $INDEX
RUN sed -i s@/archive.ubuntu.com/@/mirrors.ustc.edu.cn/@g /etc/apt/sources.list 
# 安装wine
RUN apt-get update -y  && apt-get install -y wine
RUN apt-get install -y cron \
    && apt-get install -y net-tools \
    && apt-get install -y python3 \
    && apt-get install -y python3-pip 
RUN chmod -R 777 $INDEX
RUN pip3 install requests
WORKDIR $INDEX
CMD ["/usr/bin/python3","main.py"]
