Create the bridge interface

On the compute node, we will create a bridge interface, which will allow the controller to communicate with other hosts on the network.

open /etc/network/interfaces and edit the following:

source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback


auto ens5
iface ens5 inet dhcp

auto br0
iface br0 inet static
        address 192.168.1.199
        network 192.168.1.0
        netmask 255.255.255.0
        broadcast 192.168.0.255
        gateway 192.168.1.1
        dns-nameservers 8.8.8.8
        bridge_ports ens5
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0
