[Docker] 使用ubuntu涉及時區問題

很少說，如下Dockerfile會報錯

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" ]

會卡在這裏

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:

即便輸入了6，仍是僵死在那裏。

 

解決方案：加入如下代碼

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!
