Ubuntu LXC : use bridge network

small tips.

# lxc-version lxc version: 0.9.0 # tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 13.04" # uname -ri 3.8.0-25-generic x86_64

make a bridge network and associate that bridge (br0) with a physical link(eth0).

physical link : eth0

bridge network I made : br0

auto eth0 iface eth0 inet manual auto br0 iface br0 inet static        address 192.168.100.15        netmask 255.255.255.0        network 192.168.100.0        gateway 192.168.100.254        bridge_ports eth0        bridge_stp off        bridge_fd 0        bridge_maxwait 0

restart network

# /etc/init.d/networking restart

edit existing containers configuration(/var/lib/lxc/< container name>/config ) to have those containers use the bridge network br0 which is associated with eth0.

container name : ubuntu-cn1

# less /var/lib/lxc/ubuntu-cn1/config # Template used to create this container: ubuntu # Template script checksum (SHA-1): 6f468a9a658112f6420fb39d2ab90a80fd43cd22 lxc.network.type = veth lxc.network.hwaddr = MAC address #lxc.network.link = lxcbr0 lxc.network.link = br0

edit LXC’s config ( default.conf ) to have containers which I build next time use bridge network.

# less /etc/lxc/default.conf lxc.network.type = veth #lxc.network.link = lxcbr0 lxc.network.link = br0 lxc.network.flags = up
