Comment 1 for bug 1836885

Proposal for how we could solve this:

1. Add a new relation to the openstack-integrator charm that looks like this:

provides:
  loadbalancer:
      interface: public-address

(Notice that this matches the loadbalancer relation provided by the kubeapi-load-balancer.)

2. Deploy CDK without the kubeapi-load-balancer, and instead relate the masters to the new loadbalancer relation on the openstack-integrator.

3. In the openstack-integrator, add handler code for the loadbalancer relation that will create a new Octavia LB that will balance across the k8s masters.

Is this an acceptable approach?
