os-net-config
host network configuration tool
An implementation of the ‘network configuration’ spec @ https://review.opendev.org/#/c/97859/. The intention is for this code to be moved under the tripleo project in due course.

Release Notes
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)
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: em1Configure an OVS bridge on top of an OVS bond
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: em2Configure a tagged VLAN interface on top of an OVS bridge
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.
