I'm not a fan of this logic, also because it does not support 'dhcp' (in which case it should IMO fail instead). But maybe we can figure out an IP if SDN is in use to support the dhcp case if there are static/permanent leases? (@Stefan?) I think this should be handled with a separate key in the containers network configuration. Maybe a "setup" property which defaults to "container" and can be set to "host" (not sure if we ever need more, if we know we don't, it could be a boolean...) > interface configuration is usually managed by processes within the > container.
