container command relies on docker's --net and --ip.
podman has different syntax [1] for setting static ip in bridged networks.
Error: --ip can only be set when the network mode is bridge: invalid argument
configuring static ip updates vyos-container-{name}.service and reverting the static address (revert, delete container name ... network ... address ...) in the VyOS config doesn't update the service.
