LXDのUbuntu18.04コンテナのLAN設定

LXDのUbuntu18.04コンテナのLAN設定を忘れないようにメモ

コンテナのeth1にDHCPアドレスを振る設定

host$ lxc ls u18test
+---------+---------+---------------------+-----------------------+------------+-----------+
|  NAME   |  STATE  |        IPV4         |          IPV6         |    TYPE    | SNAPSHOTS |

host$ lxc exec u18test bash
root@u18test:~# cat /etc/netplan/50-cloud-init.yaml 
# This file is generated from information provided by

network:
    version: 2
    ethernets:
        eth0:
            dhcp4: true
root@u18test:~# cat /etc/netplan/70-eth1.yaml
network:
    version: 2
    ethernets:
        eth1:
            dhcp4: true

追記)
ちなみにコンテナへeth1を追加するには
host$ lxc config device add u18test eth1 nic nictype=macvlan parent=eno2
