配置Dockerfile镜像时修改，这样打包出来的镜像文件是需要的时区的。
不然就会如上图所示，导致获取时间无论哪个时区都是utc的问题，这样在代码获取时间的时候，会出现时间不同步，导致后续的一系列未知问题出现。
所以建议在每个docker file构建的时候，推荐安装tzdata
Apline
FROM alpine:latest
ENV TZ=Asia/Shanghai \
LANG=zh_CN.UTF-8
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories && apk update
RUN apk add --no-cache mysql mysql-client tzdata && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtimeCentos
未受影响，可以不安装
Ubuntu
