Hi Kristjon,
I think that the problem is that the IRATI kernel components don't support
the use of different kernel namespaces right now. So I would go with the
demonstrator or Rumba with KVM/QEMU VMS.

Hi,
I’m trying to set up a testbed of RINA nodes using Docker containers.
Nodes consist of instances of ubuntu:16.04 container, where IRATI stack is
build successfully. The host where containers run is Ubuntu 16.04 as well.
I have mapped /dev and /lib/modules so containers can use host’s kernel
modules. Containers run in privileged mode with all capabilities. Open
vSwitch is used to connect containers.
In a simple scenario (Node A <———> Node B), IPCM can start correctly in
NodeA, but not in NodeB.
It looks like nodes cannot open /dev/irati-ctl at the same time.
The error I get when starting IPC Manager Daemon:
*root@NodeB:/bin# ./ipcm -c /etc/ipcmanager.conf -l DEBUG*

Have someone tried this? Any solution so that I can run several containers
in a host?
Otherwise, I will try demonstrator or rumba with QEMU.
Cheers,
Kristjon
