How to run a Docker container created without the -ti option?

Question

System administration

Hey!
Played around with docker and can't find info on running a container created without the -ti option.
Here's what I mean:
1) Create container # docker run --name="test" ubuntu
2) Test: # docker ps -a

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
2f1c532c21aa        ubuntu              "/bin/bash"         5 minutes ago       Exited (0) 3 minutes ago                       test

3) Try to run: # docker start -ai test
4) Check # docker ps , empty
Question: how to get inside such a container? why is this happening?

Answer 1

Do like everyone else:
just don't forget that docker writes std-output to the file and needs to be cleaned sometimes
