Docker Containers have disappeared in any list command

  docker, docker-compose, ubuntu-20.04

After a restart and 3 additional drives being installed into my Dell R710 running Ubuntu Server but Docker Containers have disappeared from the eyes of Docker. I can browse the files and see that they still exist. Any insight? I had not restarted in a while. Currently, most of my server’s functionality lies in programs running Docker, so this isn’t great.
