LXC Configuration
=================

Configuration Locations
=======================

LXC knows the following configurations locations:

* **System:** ``/etc/lxc/*``
* **Local:** ``/srv/lxc/containers/*/config``

Other locations:

* Preseed and configuration scripts: ``/etc/lxc/debconfig`` which is maintained on git.its.bfh.ch
* Auto start links: ``/etc/lxc/auto``
* Internal preseed package: ``/usr/share/lxc/packages``
* Internal lxc template scripts: ``/usr/share/lxc/templates``

Host Network
============

Enable IP Forward
-----------------

.. code-block:: bash

   echo "net.ipv4.ip_forward = 1" > /etc/sysctl.d/ip_foward.conf
   sysctl -p


Bridge Interfaces (dhcp standalone)
-----------------------------------

.. code-block:: bash

   # /etc/network/interfaces

   auto lo
   iface lo inet loopback

   iface eth0 inet manual

   auto br0
   iface br0 inet dhcp
   	bridge_ports	eth0

   	bridge_fd	0
   	bridge_hello	0
   	bridge_maxwait	0
   	bridge_stp	0


Bridge Interfaces (static standalone)
-------------------------------------

.. code-block:: bash

   # /etc/network/interfaces

   auto lo
   iface lo inet loopback

   iface eth0 inet manual

   # standalone: 192.168.0.2
   auto br0
   iface br0 inet static
   	address		192.168.0.2
   	broadcast	192.168.0.255
   	gateway		192.168.0.1
   	netmask		255.255.255.0
   	network		192.168.0.0

   	pre-up		ifconfig eth0 down
   	pre-up		ifconfig eth0 up

   	bridge_ports	eth0

   	bridge_fd	0
   	bridge_hello	0
   	bridge_maxwait	0
   	bridge_stp	0


Bridge Interface (static subnet)
--------------------------------

.. code-block:: bash

   #/etc/network/interfaces
   auto lo
   iface lo inet loopback

   iface eth0 inet manual

   # subnet: 192.168.0.1/24
   auto br0
   iface br0 inet static
   	address		192.168.0.1
   	broadcast	192.168.0.255
   	netmask		255.255.255.0
   	network		192.168.0.0

   	pre-up		brctl addbr br0
   	post-down	brctl delbr br0

   	bridge_fd	0
   	bridge_hello	0
   	bridge_maxwait	0
   	bridge_stp	0


Container Network

Physical Network
----------------

.. code-block:: bash

   lxc.network.type = phys
   lxc.network.flags = up
   lxc.network.hwaddr = 00:FF:00:00:00:03
   lxc.network.link = eth1
   lxc.network.name = eth0
   lxc.network.ipv4 = 192.168.0.3/24
   lxc.network.ipv4.gateway = 192.168.0.1
