Bridging, bonding and netplan

Question

I'm trying to set up a bridge over a bond for LXD using netplan.
This is my current configuration:

network:
  version: 2
  renderer: networkd
  ethernets:
    id0:
      match: {name: "eno[1-2]"}
      dhcp4: true
      wakeonlan: true
    switchports:
      match: {name: "eno[3-4]"}
  bonds:
    bond0:
      interfaces: [switchports]
      dhcp4: true
      parameters:
        mode: 802.3ad
  bridges:
    br0:
      interfaces: [bond0]
      dhcp4: true

As you can see it's pretty straighforward.
However, after applying this configuration, the IP address assigned to bond0 disappeared and no IP is being assigned to LXD containers (which use br0) or the bridge interface itself.
Could someone please explain what's happening?

Answer 1

You appear to have dhcp4: true set on both the bond, and the bridge which includes the bond. You should likely only be running dhcp on the bridge.
