在 Docker 容器上的 Ubuntu 20.04 上安装 Erlang/Elixir / 静默安装

Question

esl-erlang我正在尝试在 Ubuntu 20.04 docker 映像上安装 Erlang/Elixir，但我被有关地理区域的提示挂断了。如何静音或设置默认值US？

这是我的 Docker 镜像：

FROM ubuntu:20.04
ENV LANG=en_US.UTF-8

RUN apt-get update -y
RUN apt-get install -y wget gnupg2 inotify-tools locales && \
  locale-gen en_US.UTF-8

RUN wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && dpkg -i erlang-solutions_2.0_all.deb

RUN apt-get update -y
RUN apt-get install -y esl-erlang 
RUN apt-get install -y elixir


CMD ["/bin/bash"]

下面是docker挂掉的提示：

怎样才能esl-erlang让提示音静音呢？

Answer 1

DEBIAN_FRONTEND=noninteractive运行前设置apt-get install：

RUN DEBIAN_FRONTEND=noninteractive apt-get update && apt-get install -y ...

或者

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y ...

UPD1：只是为了添加更多上下文，这不是 esl-erlang 造成的，而是此提示来自安装 tzdata。

UPD2：如果 UTC 不是您喜欢的，您可能需要像这样手动设置时区

sudo ln -s /usr/share/zoneinfo/America/<CITY> /etc/localtime

其中 CITY 是来自的城市之一ls /usr/share/zoneinfo/America/
