Getting nothing in PS afx in docker

Vershion: Docker version 17.05.0-ce, build v17.05.0-ce
OS: Alpine (as host)

(any other info needed please say and i get)

question:

Hay all

I have recently created an virtual system and installed alpine and docker.

I have created two containers, but when i run an “ps afx” from in side the containers i don’t see anything
just

ps afwww    
  PID TTY      STAT   TIME COMMAND
 1027 ?        Ss     0:00 sh
 1030 ?        R+     0:00  \_ ps afwww
  845 ?        Ss     0:00 sh
  921 ?        S+     0:00  \_ bash

but i know the container is running an number of other apps

When i do an “ps afx” on the host system (not inside the container), i see all the things that are running in the containers.

Any advise on it would be welcome
