### exposed profile with a regular linux br0 interface bridge
|
||||
|
||||
You can configure an Ubuntu server with a br0 interface
|
||||
|
||||
```conf
|
||||
# /etc/network/interfaces
|
||||
auto lo
|
||||
iface lo inet loopback
|
||||

||||
# br0 bridge in dhcp configuration with ethernet
|
||||
# port ens2 added to it.

||||

|

### ubuntu:16.04 using only dhcp for two nics
|
||||
So the example here is tested with eth0 and eth1 connected to
|
||||
br0 and lxdbr1 respectively. You need post-up hooks for both eth0 and
|
||||
eth1 inside the containers, in order to specify the default route, eth0 gets it's configuration
|
||||
dynamically by default from cloud-init. So disable cloud-init by
|
||||
creating the following file on the container.
|
||||
|
||||
```conf
|
||||
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
|
||||
network: {config: disabled}
|
||||
```
|
||||
|
||||
Then, on the container describe the interfaces.
|
||||
|
||||
```conf
|
||||
# /etc/network/interfaces
|
||||
auto lo
|
||||
iface lo inet loopback
|
||||
|
||||
auto eth1
|
||||
iface eth1 inet dhcp
|
||||
post-up route del default dev eth1
|
||||
|
||||
auto eth0
|
||||
iface eth0 inet dhcp
|
||||
post-up route add default dev eth0 via 192.168.1.1
|
||||
```
|
||||
|
||||
and delete /etc/network/interfaces.d/50-cloud-init.cfg
|
||||
|
||||
```bash
|
||||
rm /etc/network/interfaces.d/50-cloud-init.cfg
|
||||
```
|
||||
|
||||
The advantage to this scenario is now you can make copies of the container
|
||||
without having to update the network descriptions, because both interfaces
|
||||
will solicit addresses via dhcp.
