[Docker] 使用ubuntu涉及时区问题

很少说，如下Dockerfile会报错

FROM ubuntu:latest

RUN apt-get update && apt-get install -y \
    ssh \
    build-essential \
    gcc \
    g++ \
    gdb \
    clang \
    cmake \
    rsync \
    tar \
    python \
    vim \
    automake \
    openssh-client \
    openssh-server \
  && apt-get clean

RUN PermitRootLogin yes \
  && UsePAM no

RUN passwd root

COPY entrypoint.sh /sbin
RUN chmod +x /sbin/entrypoint.sh
ENTRYPOINT [ "/sbin/entrypoint.sh" ]

会卡在这里

Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

  1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Etc
  2. America     5. Arctic     8. Europe    11. SystemV
  3. Antarctica  6. Asia       9. Indian    12. US
Geographic area:

即便输入了6，仍是僵死在那里。

 

解决方案：加入如下代码

RUN export DEBIAN_FRONTEND=noninteractive \
    && apt-get update \
    && apt-get install -y tzdata \
    && ln -fs /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && dpkg-reconfigure --frontend noninteractive tzdata

 

Have fun with Docker!
