linux - Finding Docker container processes? (from host point of view)
I am doing some tests on docker and containers and I was wondering:

You can use docker top command.
This command lists all processes running within your container.
For instance this command on a single process container on my box displays:
UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
root                14097               13930               0                   23:17               pts/6               00:00:00            /bin/bash

All methods mentioned by others are also possible to use but this one should be easiest.
Update:
To simply get the main process id within the container use this command:
 docker inspect -f '{{.State.Pid}}' <container id>
