Docker run doesn't work

I've just got started with Docker and managed to install it.

Next, I watched and followed the instruction from this video at minute 14:00

wolf@linux:~$ docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
ubuntu        latest    f643c72bc252   3 weeks ago     72.9MB
hello-world   latest    bf756fb1ae65   11 months ago   13.3kB
wolf@linux:~$ 

I tried to run it ...

wolf@linux:~$ docker run -p 8080:80 --name hello -d hello-world
007somehashhere
wolf@linux:~$ 

However, when I checked it with docker ps, it's not there.

wolf@linux:~$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
wolf@linux:~$ 

I tried to restart it, but it doesn't work too.

wolf@linux:~$ docker start hello 
hello
wolf@linux:~$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
wolf@linux:~$ 

Tried different command, but doesn't help much.

wolf@linux:~$ docker container run -d -t hello-world
007somehashhere
wolf@linux:~$ 

wolf@linux:~$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
wolf@linux:~$ 

What's wrong in this case and how do I make it work?
