Can the default for the creation of a floating IP for loadbalancers be changed (for a whole cluster)?

[kastl-ars]

Dear maintainers,

in our use case it is not only enough, it is mandatory that services that create a loadbalancer do NOT get a floating IP address, but only the "internal" IP address.

This can be achieved by setting an annotation on each service:

service.beta.kubernetes.io/openstack-internal-load-balancer

If 'true', the loadbalancer VIP won't be associated with a floating IP. Default is 'false'. This annotation is ignored if only internal Service is allowed to create in the cluster.

from the documentation

Is it possible to change the default behaviour for a whole kubernetes cluster so new services do not get a floating IP address by default?

Or is this a setting that comes from the underlying OpenStack platform?

Or is it not configurable at all?

We would like to avoid having to use a validationAdmissionController or mutatingAdmissionController just to make sure all services have that annotation set, if this is possible?

Thanks in advance!

Kind Regards,
Johannes
