I'm making this post to you, because I'm currently doing a docker file from a UBUNTU 20.04.
In my dockerfile I run installs which for some require multiple choice questions with "interactive" answer.
So I wanted to know how I could automate the thing.
I leave you attached my docker file, I put a hash in front of the packages causing me problem.
RUN apt-get update
RUN rm -f /etc/localtime && ln -s /usr/share/zoneinfo/Europe/Paris /etc/localtime
RUN apt-get install apache2 -y
RUN apt install gnupg
RUN apt-get install wget
RUN cd /tmp
RUN wget https://dev.mysql.com/get/mysql-apt-config_0.8.20-1_all.deb
#RUN apt install ./mysql-apt-config_0.8.20-1_all.deb -y
