Question

我正在尝试在 Ubuntu 20.04 docker 映像上安装 Erlang/Elixir，但我被一个地理区域的 esl-erlang 提示挂断。如何静音或将默认值设置为 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"]

这里是docker挂断的提示：

如何使 esl-erlang 提示静音？

Answer 1

在运行 DEBIAN_FRONTEND=noninteractive 之前设置 apt-get install：

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

或

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

UPD1：只是为了添加更多上下文，不是 esl-erlang 导致它，而是这个提示来自安装 tzdata。

UPD2：如果 UTC 不是您喜欢的东西，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 ls /usr/share/zoneinfo/America/ 的城市之一

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