How do I run a docker container by its container name?

Question

For example once I create a container with name of "duplo":

docker run --name="duplo" -it /bin/bash -c "sudo /build/backup.sh".

How do I execute an additional command within the container after it exits? I can see it listed by docker ps -a.

`commit` and then `run`: https://stackoverflow.com/a/30269330/118613 — Alexander Azarov, Jul 06 '17 at 09:18

As long as it is stopped, you can do nothing.

Maybe you can start it

see the doc

and if it says running, you can connect and launch some commands using

docker exec -it duplo bash

or maybe just modify a string in a file

docker exec -it duplo sed...

, see the associated doc
