Reconstruct Docker containers config from a running machine? (kbin.social)

Hi! I've inherited a machine installed by somebody else who's no longer in the company or the country. The machine is running just fine, but i see no Dockerfiles or docker-compose.yml, and this looks like something that came from a Compose file with a few linked containers.

Is it possible to reconstruct that info from the running containers? I'm still a raw Docker newbie at this point so i don't know if this is even possible, would be helpful not to have to try and contact the person who set it up.

Well you can at least connect to the running container with a shell and see what processes are running, and maybe copy some binaries and config out of it into the local file system.

You can also use $ docker inspect to get some more info.
