===============================
os-net-config
===============================
host network configuration tool
An implementation of the 'network configuration' spec @
https://review.openstack.org/#/c/97859/.
The intention is for this code to be moved under the tripleo project in due course.
* Free software: Apache license
* Documentation: http://docs.openstack.org/developer/os-net-config
* Source: http://git.openstack.org/cgit/openstack/os-net-config
* Bugs: http://bugs.launchpad.net/os-net-config
Features
--------
The core aim of this project is to allow fine grained (but extendable)
configuration of the networking parameters for a network host. The
project consists of:
* A CLI (os-net-config) which provides configuration via a YAML or JSON
file formats. By default os-net-config uses a YAML config file located
at /etc/os-net-config/config.yaml. This can be customized via the
--config-file CLI option.
* A python library which provides configuration via an object model.
YAML Config Examples
--------------------
* Configure an OVS bridge with a single attached interface (port)
.. code-block:: yaml
network_config:
-
type: ovs_bridge
name: br-ctlplane
use_dhcp: true
ovs_extra:
- br-set-external-id br-ctlplane bridge-id br-ctlplane
members:
-
type: interface
name: em1
..
* Configure an OVS bridge on top of an OVS bond
.. code-block:: yaml
network_config:
-
type: ovs_bridge
name: br-ctlplane
use_dhcp: true
members:
-
type: ovs_bond
name: bond1
members:
-
type: interface
name: em1
-
type: interface
name: em2
..
* Configure a tagged VLAN interface on top of an OVS bridge
.. code-block:: yaml
network_config:
-
type: ovs_bridge
name: br-ctlplane
use_dhcp: true
members:
-
type: interface
name: em1
-
type: vlan
vlan_id: 16
addresses:
-
ip_netmask: 192.0.2.1/24
..
Provider Configuration
----------------------
Providers are use to apply (implement) the desired configuration on the
host system. By default 3 providers are implemented:
* Ifcfg: persistent network config format stored in
/etc/sysconfig/network-scripts
* ENI: persistent network config format stored in /etc/network/interfaces
* iproute2: non-persistent provider which implements the config using
iproute2, vconfig, etc... (implementation in progress)
When using bin/os-net-config the provider is automatically selected based on
the host systems perferred persistent network type (ifcfg or ENI). This can
be customized via the --provider CLI option.
