Docker基礎鏡像時區修改

我們在構建自己的docker鏡像時，系統默認一般為UTC，我們需要改為CST

Ubuntu16.04基礎鏡像： 

FROM ubuntu:16.04
MAINTAINER xx@example
RUN ln -sf /usr/share/zoneinfo/Asia/ShangHai /etc/localtime
RUN echo "Asia/Shanghai" > /etc/timezone
RUN dpkg-reconfigure -f noninteractive tzdata

 Alpine3.6基礎鏡像：

 

FROM alpine3.6
MAINTAINER [e-mail]
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories
RUN apk add --no-cache tzdata \
    && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && echo "Asia/Shanghai" > /etc/timezone \
    &&rm -rf /var/cache/apk/* /tmp/* /var/tmp/* $HOME/.cache
