docker ubuntu 不选时区

在用ubuntu:18.04基本镜像进行构建的时候。出现啦选择时区的地方，然后会卡住。

FROM ubuntu:18.04
#env 环境变量
ENV AUTHOR="xianyunyehe" PWD="."
#复制源
COPY ${PWD}/sources.list /etc/apt/sources.list
#容器启动执行的脚本程序
#CMD [ "" ]
#定义挂载的卷
VOLUME [ "/tmp" ]
#对外暴露的端口
EXPOSE
#工作目录 构建的每层操作都在该目录下进行
WORKDIR /tmp
#指定用户
USER root
 
# 当以当前镜像为基础镜像，去构建下一级镜像的时候才会被执行
#
#RUN mkdir /app
#WORKDIR /app
#ONBUILD COPY ./package.json /app
#ONBUILD RUN [ "npm", "install" ]
 
#执行命令
RUN buildDeps='gcc libc6-dev make' \
    && apt-get update \
    && apt-get install -y $buildDeps \
    && apt-get install -y php \
    && apt-get purge -y --auto-remove $buildDeps

可以通过配置环境变量，来跳过这个步骤
