Dockerfile – 如何将答案传递给提交后apt-get安装？
在我的Dockerfile中，我试图安装jackd2软件包：
RUN apt-get install -y jackd2 它安装正确，但安装后，我可以看到以下提示：
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，我想回答是或不是，打回车，继续前进，但我不知道如何在docker文件中编写脚本，我的构build挂在那里。
这个答案解释了“假设是”和非交互模式之间的区别。
我还发现了一个在这里安装jackd2的Dockerfile的示例，在安装jackd2之前将DEBIAN_FRONTEND设置为'noninteractive' 。
