The version of lxd on Ubuntu 16.04 LTS is a little anemic with
regards to explaining how to set up networking. I would assume that
in many cases it is desirable for the container to be able to receive
network requests. By default lxd configures a NAT bridge which means
the container can go out, but without some work can't receive messages
in.
Install bridge-utils
apt install bridge-utils
Modify /etc/network/interfaces and add
auto br0
iface br0 inet dhcp
bridge_ports eno1
iface eno1 inet manual
Restart networking on host
service networking restart
Update default profile in lxc
lxc profile edit default
devices:
eth0:
name: eth0
nictype: bridged
parent: br0
type: nic
Restart any existing containers
Assuming you have DHCP configured on the interface containing the bridge, your containers will now get DHCP addresses.
