From 4.0 contrail services will be deployed as containers, so one should have knowledge to connect to docker containers and work with in order to work with contrail services.
$ docker ps

Run the command "docker exec -it bash" to connect to the container and get bash prompt
Once you connect to the container, you can work as if you are in the machine where controller services are running (like accessing logs from /var/log/contrail etc).
[root@harish-centos-test-1 ~]# docker exec -it controller bash
root@harish-centos-test-1:/#
Note that at this moment you would see similar prompt within the container and outside of container, but running "ps -efw" within the container only shows the process running within that container.
root@harish-centos-test-1:/# ps -efw
