I have simple example from official guide at docker website.

I run the following:

Took me a while to find the right answer, but you will have to manage this process from within the container. When you run docker top a66 from the host, the PIDs are from your host, although that's not quite the case if using Cygwin. Regardless, you will need to bash or what-have-you back into your container and use commands like ps aux and kill while in the container to find and manage the different PIDs for the same processes there.
