回答"29"到xorg的apt-get install提示符

Question

我正在使用docker来组合一个脚本,当这个包xorg询问键盘的原始国家的提示时它会卡住,我会附上图像.

从我读过的其他答案中,我已经尝试过像这样的命令

RUN echo "29" | apt-get install -y xorg

但它似乎没有用.我不知道如何得到这个以自动回答29.任何帮助表示赞赏.

我在Dockerfile中看到了很多问题.

1. 在Dockerfile中定义一个卷几乎没有价值.最好在docker-compose.yml中定义它,或者作为run命令的一部分.我有一篇博文来解决这个问题.

2. apt-get update从后面的apt-get install命令中拆分可能apt-get install会导致失败的情况.关于这一点的最佳实践中有一节.

3. 对于您的错误消息,我将在非交互模式下运行apt-get.如果在安装期间需要设置非默认值,也可以预先配置debconf.

4. 将每个apt-get拆分为单独的RUN命令会创建大量过多的层,这些层应尽可能合并.最佳实践文档中也对此进行了描述.

这是一个安装命令的示例,对我来说,考虑到上述因素:

FROM ubuntu:16.04

RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive apt-get install -y \
      build-essential \
      xorg \
      libssl-dev \
      libxrender-dev \
      wget \
      gdebi \
      libxrender1 \
      xfonts-utils \
      xfonts-base \
      xfonts-75dpi
