I have an application environment where two containers need to talk to each other. Container A gets a message from Container B, and Container A initiates a connection back to Container B using the IP address of the connection from B.
So I need the container IP addresses to be on the same network as the hosts. I followed this Docker + Bridges + DHCP instruction.
Problem: I never get the eth0 device in the container.
My container is started from ubuntu:14.04, I added lxc to it.
The container is started with additional params --net=none --lxc-conf=\"lxc.network.type=veth\" \
--lxc-conf=\"lxc.network.link=br0\" --lxc-conf=\"lxc.network.name=eth0\" --lxc-conf=\"lxc.network.flags=up\" "
But I don't see that interface in the container.. ifconfig returns only for lo.
What did I miss? My container has a custom startup script.
Edit: My host is runnung ubuntu 14.04 latest.
the host has lxc installed as well as docker (installed today).
Docker inspect on the container shows the lxc-conf keys defined.
It's like lxc is not executing, but I don't know why. Debug of lxc invocations is a known issue with no current solution.
