回答'29'apt-get安装提示为xorg

Question

我使用docker放在一起的脚本，它的卡住，当这个软件包xorg询问键盘的原产国的提示时，我会附上图片。

我从其他的答案试图管道在命令这样我读过

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

但它似乎并没有工作。我不知道我如何得到这个自动回答29.任何帮助表示赞赏。

有相当我看到了Dockerfile提供了一些问题。

1. 定义Dockerfile内部的卷几乎没有值。在docker-compose.yml中定义它或者作为运行命令的一部分来定义它会更好。我有一个blog post解决这个问题。

2. 从后面的apt-get install命令中拆分apt-get update可能会导致apt-get install失败的情况。有关best practices的部分内容。

3. 对于您的错误消息，我会在非交互模式下运行apt-get。如果您在安装期间需要设置非默认值，您也可以使用preconfigure debconf。

4. 将每个apt-get拆分为单独的RUN命令会产生大量过多的图层，应尽可能将这些图层合并。这在best practices文档中也有描述。

下面是对我的作品的安装命令的样本考虑到上述账号：
