ps command cannot connect to the docker daemon even after adding user to docker group

Question

I have started a docker container using the following command

     vagrant@vagrant-ubuntu-trusty-64:~$ docker run -t -i ubuntu /bin/bash
     root@abb8ef669ab6:/# cd

I am able to see the container shell. However, I am not able to list the docker processes in the new shell on the host using docker ps. am I missing something here?

     vagrant@vagrant-ubuntu-trusty-64:~$ sudo usermod -aG docker vagrant
     vagrant@vagrant-ubuntu-trusty-64:~$ docker ps -a
     Cannot connect to the Docker daemon. Is the docker daemon running on this host?

I just tested this! It didn't work – Praveen reddy Dandu Mar 01 '16 at 14:41 — Praveen reddy Dandu, Mar 01 '16 at 14:41

I suppose here is the problem solution "It is neccesary add user to docker group" https://stackoverflow.com/a/33596140/2313177
