LXC Networking --> Simple Bridge
Ref: https://wiki.debian.org/LXC/SimpleBridge
Requires bridge-utils package.
$ sudo apt-get install bridge-utils
1. Edit the host's /etc/network/interfaces
# for static ip setup on the host
iface br0 inet static
bridge_ports eth0
bridge_fd 0
address 192.168.0.x
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.x
dns-nameservers 8.8.8.8
2. Edit /etc/lxc/default.conf (on host):
Change:
lxc.network.link = lxcbr0
to
lxc.network.link = br0
3. Last, check if everything is prepared for LXC:
$ sudo lxc-checkconfig
4. Edit /etc/network/interfaces on each container (static IP):
auto lo
iface lo inet loopback
auto eth0
# iface eth0 inet dhcp
iface eth0 inet static
address 192.168.0.x
network 192.168.0.0
broadcast 192.168.0.255
netmask 255.255.255.0
gateway 192.168.0.x
dns-nameservers 8.8.8.8
I hope this helps.

This is probably dumb and asked a 1000 times before but I am totally
confused by various tutorials that are either to old or do not apply
to exactly my particular needs. For the purpose of ongoing/endless
testing I'd like containers to be given an IP in the same network
range via DHCP and my WIFI (wlan0) interface.
Most examples presume an eth0 interface but that does not exist for
my day to day laptop workstation.
. router 192.168.0.1 via laptop wlan0
. kubuntu 14.10 gets 192.168.0.209
A ubuntu uptopic container currently gets 10.0.3.164 via the lxcbr0
bridge with a gateway of 10.0.3.1. I can ping the outside world so
the default ubuntu lxc networking system works just fine. I've tried
a variety of combinations of br0 bridges and iptables rules but the
right combination to "simply" allow a container to get another DHCP
IP from my router on the same network as my main WIFI link so I can
access those containers from other computers on the same 192.168.0.0/24
network.
Any tutorials or hints on how to do this?
Maybe it's not possible for containers to appear on the same /24
network as the host so surely there must be a "common" way to at least
allow containers to be visible to other hosts on the same network segment?
