Git `docker build`根据安装顺序挂起

git docker ubuntu cmake

Git `docker build`根据安装顺序挂起,git,docker,ubuntu,cmake,Git,Docker,Ubuntu,Cmake,鉴于此Dockerfile： FROM ubuntu:20.04 RUN set -ex && apt-get update RUN set -ex && \ apt-get install -y \ git RUN set -ex && \ apt-get install -y \ cmake ENV HOME_DIR /home/develop WORKDIR ${HOME_DIR} ENV TZ=A

鉴于此

Dockerfile

：

FROM ubuntu:20.04

RUN set -ex && apt-get update

RUN set -ex && \
    apt-get install -y \
    git

RUN set -ex && \
    apt-get install -y \
    cmake

ENV HOME_DIR /home/develop

WORKDIR ${HOME_DIR}

ENV TZ=America/Los_Angeles
RUN ln -snf "/usr/share/zoneinfo/$TZ" /etc/localtime
RUN echo "$TZ" > /etc/timezone

RUN apt-get update
RUN apt-get install -y tzdata

docker构建

挂起配置

如果我颠倒

git

和

cmake

的顺序，它将成功构建。为什么订单很重要

我正在MacOS 11（Big Sur）上运行Docker 20.10.5。

在安装之前，CMake包必须为

tzdata

自动选择默认选项（作为git的依赖项）。奇怪，但解决办法很简单。在

Dockerfile

顶部附近添加以下行：

FROM ubuntu:20.04

RUN set -ex && apt-get update

RUN set -ex && \
    apt-get install -y \
    git

RUN set -ex && \
    apt-get install -y \
    cmake

ENV HOME_DIR /home/develop

WORKDIR ${HOME_DIR}

ENV TZ=America/Los_Angeles
RUN ln -snf "/usr/share/zoneinfo/$TZ" /etc/localtime
RUN echo "$TZ" > /etc/timezone

RUN apt-get update
RUN apt-get install -y tzdata

当然，将

America/Los_Angeles

替换为您认为最适合您的应用程序的时区，可能

UTC

Git将perl作为其依赖项之一安装，同时安装

Term:：ReadLine

perl模块。使用此模块，在安装cmake时，debconf可以初始化

读线

前端，并可以等待输入。但是，如果您首先安装cmake，该模块在本地还不存在，并且debconf将无法设置tzdata，并将使用默认配置

如果我们先安装cmake，则日志可以证明上述情况：

通过设置DEBIAN_FRONTEND变量来抑制apt的提示，该变量可通过仅在构建期间存在的构建参数来完成（允许交互式用户执行到容器中）：

另外，请注意，更新应与安装步骤一起运行，以避免过时缓存破坏生成。
