I have been installing and exposing SSH on most of the containers I have deployed, which I know is wrong.

As I have been trying to do things in a more “devops” way I decided to do a little reading on how I can enter and leave running containers on my CentOS 7 instance without having to expose SSH or configure users.

This is when I came across nsenter↗ & docker-enter↗ . As you can see from the following instructions and terminal session installing nsenter and then using docker-enter to connect to a running container is a breeze;
