After Hello World

no running containers, but there is one on the disk:

$ docker container ls -a -s
$ docker ps -as
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES               SIZE
f6239f10a6ad        hello-world         "/hello"            8 seconds ago       Exited (0) 7 seconds ago                       lucid_snyder        0 B (virtual 1.84 kB)

• I keep fortgeting what does that -s do, so I run:

$ docker ps --help

There is also an image

$ docker images
$ docker image ls
$ docker image list
