Assign static IPs to my containers that are LAN routable when I already have a bridge on the host?

I have a Ubuntu 18.04 host which is running virtual machines, docker containers, and now LXC containers.

That machines has a network card, eno1, a br0 bridge that uses eno1, and lxdbr0 which is the default LXD bridge config.

I’m using Ansible to create new containers, and I’d like to be able to give those containers a static IP address.

If I do:

devices:
  eth0:
    name: eth0
    nictype: macvlan
    parent: br0
    type: nic
    ipv4.address: 192.168.1.10

Then lxc ls shows that the container has no IP.

If I put ipv4.address: auto, then the container gets a 192.168.1.xxx IP in my DHCP range and I can ping it from another host, but the IP is dynamic.

I also tried creating a profile with

  user.user-data: |
    # cloud-config
    package-upgrade: true
    packages:
      - python-minimal
    timezone: Etc/UTC
    network:
      version: 2
      ethernets:
        eth0:
          dhcp4: false

and then create the container with

  user.user-data: |
    # cloud-config
    network:
      version: 2
      ethernets:
        eth0:
          dhcp4: false
          addresses: [192.168.1.10/24]

I hoped it would merge the profile’s cloud-init and the manually supplied one. But no, no luck.

How do I make this work? Is there a way without modifying the lxdbr0 config or the dnsmasq config file?
