如何回答dockerfile中的安装问题？ [英] How to answer install question in dockerfile?

问题描述

我尝试使用dockerfile安装某些东西。
但是当我运行命令时，我必须回答以下问题：

I tried to install something using dockerfile. But when I run the command, I have to answer the question like following:

输入

6

72

我的dockfile如下所示，但似乎不起作用。

My dockfile is like following, but seems not working.

FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y expect
RUN apt-get -y install software-properties-common 
RUN apt-add-repository ppa:ondrej/php
expect "Press [ENTER] to continue or Ctrl-c to cancel adding it. " { send "\n" }
RUN apt-get -y install php7.1 php7.1-fpm 
expect "Please select the geographic area in which you live. " { send "6\n" }
expect "Please select the city or region corresponding to your time zone. " { send "72\n" }
RUN -y apt-get install nginx

推荐答案

我测试了您的Dockerfile，而不必回答任何问题，但是如果您想在运行命令时自动回答，则可以使用 yes （用于 y和 n响应）或 echo 。

I tested your Dockerfile and didn't have to answer any question, but if you want to auto answer when you run a command, you can use yes (for "y" and "n" responses) or echo.

例如：

是| <您的命令>

是n | <您的命令> n响应

回声| <您的命令> echo生成新行（输入）

echo | <YOUR COMMAND> echo generate a new line (enter)

echo some response | < YOUR COMMAND> 带有某些响应的响应
