Dockerfile-如何将答案传递给apt-get安装提示？ [英] Dockerfile - How to pass an answer to a prompt post apt-get install?

问题描述

在我的Dockerfile中，我正在尝试安装jackd2软件包：

In my Dockerfile, I am trying to install jackd2 package:

RUN apt-get install -y jackd2

它可以正确安装，但是安装后，我会看到以下提示：

It installs properly, but after installation, I can see the following prompt:

If you want to run jackd with realtime priorities, the user starting jackd
needs realtime permissions. Accept this option to create the file
/etc/security/limits.d/audio.conf, granting realtime priority and memlock
privileges to the audio group.

Running jackd with realtime priority minimizes latency, but may lead to
complete system lock-ups by requesting all the available physical system
memory, which is unacceptable in multi-user environments.

Enable realtime process priority? [yes/no]

```

在这一点上，我想回答是或否，按Enter键并继续，但是我不知道如何在dockerfile中编写脚本，而我的构建就挂在那里。

At this point, I would like to answer with either yes or no, hit enter and move on but I have no idea how to script this inside a dockerfile and my build hangs right there.

推荐答案

此答案解释了假设是和非交互模式之间的区别。

This answer has an explanation for the difference between "assume yes" and a non-interactive mode.

我还找到了一个示例一个在此处处安装jackd2的Dockerfile，并且设置 DEBIAN_FRONTEND 到'noninteractive'，然后安装jackd2。

I also found an example of a Dockerfile that installs jackd2 here, and it's setting DEBIAN_FRONTEND to 'noninteractive' before installing jackd2.
