Docker container on CoreOs running a OpenVPN Client

Vote count:

0

i'm using CoreOS (522.6.0) to build a cluster running OpenVPN client.

Each container is using ubuntu:latest

I run a container with the privileged and device option to use the tun device to run Openvpn:

sudo docker run -P --name rs1_srv30 -d dev24/mongodb --replSet rs2 --noprealloc --smallfiles --privileged --device /dev/net/tun

When i press ENTER, it displays a hash and when i run docker ps -a:

CONTAINER ID        IMAGE                  COMMAND                CREATED             STATUS                        PORTS               NAMES

The journalctl:
