Example Playbook

Example vars setup:

el_network_interfaces:
  - iface: ens32
    type: ethernet
    ip4: '192.168.0.10/24'

  - iface: ens33
    type: bond-slave
    master: bond0

  - iface: bond0
    type: bond
    bonding_mode: 4
    bridge: br0

  - iface: bond0.10
    type: ethernet
    vlan: yes

  - iface: br0
    type: bridge
    ip4: '10.0.0.10/24'
    gw4: '10.0.0.1'

Then simply run the role:

- hosts: servers
  roles:
    - el-network

OVS

Simple OVS support exists to integrate an interface and/or bridge into OVS. Note: This role does not install OVS, that is left up to the admin.

el_network_interfaces:
  - iface: ens33
    type: ethernet
    bridge: br-ex
    ovs: yes

  - iface: br-ex
    type: bridge
    ovs: yes
    ip4: '172.16.0.10/24'
