This will configure a macvlan-trunk-based network based on a parent trunk device. macvlan has certain limitations in addition to its advantages when in bridge mode so be sure to either understand what is being accomplished here before making an attempt or else do so in a sandbox virtual network.

Improper configuration can disrupt network connectivity both to the host being configured as well as to all other hosts on the network to which it is attached.

See also ansible-systemd-networkd-macvlan-trunk.

Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.

The range from which to auto-assign addresses for this docker host. Ensure it doesn't overlap any real hosts or else assign static IPs to each docker container.

The gateway present on your local network.

Your network's subnet.

The network's name as it will be configured in docker.

The parent device for macvlan devices.

There is no playbook dependency but the example uses my related systemd_networkd_macvlan_trunk for ease of deployment.
