I've got a home server running with a bunch of linux containers and they're all getting their ip addresses assigned automatically via dhcp on my router.

I'd like to be able to assign ip addresses manually to each container but I seem to be having a bit of trouble finding a working example of how to do that exactly.

I'm not the biggest networking expert so I'm about to butcher some terminology on this next part. I have my containers setup so that they're getting addresses that start with 192.168.1.xxx and are accessible by other devices on my network instead of the private? addresses (10.whatever) that the default LXD settings give.

An example of some of my containers (deluge is also connected to a vpn):

+------------+---------+--------------------------------+------+------------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+------------+---------+--------------------------------+------+------------+-----------+
| deluge | RUNNING | 192.168.1.17 (eth0) | | PERSISTENT | 0 |
| | | 10.3.83.122 (tun0) | | | |
+------------+---------+--------------------------------+------+------------+-----------+
| emby | RUNNING | 192.168.1.19 (eth0) | | PERSISTENT | 0 |
+------------+---------+--------------------------------+------+------------+-----------+
| grocery | RUNNING | 192.168.1.52 (eth0) | | PERSISTENT | 0 |
+------------+---------+--------------------------------+------+------------+-----------+ 

One example tutorial I tried that didn't seem to work is this blog post on medium. I like the simplicity of his method but unfortunately, it seems to have 0 effect on my containers. His /etc/default/lxd-bridge file is slightly different than mine though. He has LXD_BRIDGE="" whereas mine is set to LXD_BRIDGE="br0".

Contents of my host /etc/network/interfaces

# this is empty
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto br0
iface br0 inet dhcp
 bridge_ports enp7s0

iface enp7s0 inet manual

Contents of my default lxc profile which is currently assigned to all containers:

config:
 environment.http_proxy: ""
 user.network_mode: ""
description: Default LXD profile
devices:
 eth0:
 name: eth0
 nictype: bridged
 parent: br0

All my containers are running recent versions of ubuntu.

LXD version 2.0.11

Please let me know if there's any more information that I can provide.
