I am creating a Dockerfile using the centos:7 base image.
I need to edit the file at etc/sudoers and append NOPASSWD privileges to it for a new consul user and some groups.
I have looked up in forums that its better to use sudo visudo while editing the sudoers file instead of using cat? However, I am still a beginner and any pointers regarding how that can be written in a Dockerfile would be helpful.
