How to retain docker alpine container after “exit” is used?

Question

Like for example if I use command docker run -it alpine /bin/sh it starts a terminal after which I can install packages and all. Now when I use exit

Answer 1

You should use docker start, which allows you to start a stopped container. If you didn't name your container, you'll need to get it's name/id using docker ps.

For example,

$docker ps
CONTAINER ID        IMAGE                        COMMAND
4c01db0b339c        alpine                       bash    

$docker start -i -a 4c01db0b339c
