Docker container not starting

Question

I'm trying to run this docker example. Yet it appears that I can't start my docker container.

sudo docker stop aff28c5dab3f
sudo docker start aff28c5dab3f
sudo docker ps
ID                  IMAGE               COMMAND             CREATED             STATUS              PORTS

sudo docker ps -a
ID                  IMAGE                     COMMAND                CREATED             STATUS              PORTS

and when I try to run sudo docker attach aff28c5dab36, I see Impossible to attach to a stopped container, start it first

Answer 1

I forgot to attach to the container, and hence was getting the error. I ran sudo docker attach aff28c5dab36 and now everything works fine.
