How do I show running docker processes?

[petulia3478]

We saw this in another article where there was nothing running. This is what you would see if Tomcat was running inside a container.

$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
