Description Luis Tomas Bolivar 2018-12-07 14:10:59 UTC 
When deploying a multi-master setup with kuryr enabled, the OSEv3 vars get overwritten by the kuryr vars at the dynamic inventory, therefore missing important information.

This for instance leads to removing the value for 'openshift_master_cluster_hostname', which makes all the master nodes to point to one of the masters instead of to the loadbalancer in front of them. Thus, if that master is shutdown, the complete cluster will be down as the other master are trying to reach it.
Comment 2 Jon Uriarte 2018-12-21 09:23:09 UTC 
Verified in openshift-ansible-3.11.59-1.git.0.ba8e948.el7.noarch on top of OSP 13 2018-12-13.4 puddle.

Verification steps:
- Deploy OCP 3.11 on OSP 13 (with ansible 2.5)
- Run the dynamic inventory:
  ยท /usr/share/ansible/openshift-ansible/playbooks/openstack/inventory.py
- Check the output contains the "openshift_master_cluster_hostname" inside inventory['OSEv3']['vars']:

    "OSEv3": {
        "hosts": [
            "app-node-0.openshift.example.com",
            "app-node-1.openshift.example.com",
            "master-0.openshift.example.com",
            "infra-node-0.openshift.example.com"
        ],
        "vars": {
            "kuryr_openstack_api_lb_ip": "172.30.0.1",
            "kuryr_openstack_auth_url": "http://10.46.22.28:5000//v3",
            "kuryr_openstack_password": "redhat",
            "kuryr_openstack_pod_project_id": "fca7a9346b8947c6a20e3b3e974243f5",
            "kuryr_openstack_pod_router_id": "c1c4f31d-bc92-441b-953b-b73c0a77ad2f",
            "kuryr_openstack_pod_sg_id": "33262e49-2872-4162-9e6c-8d4593772a36",
            "kuryr_openstack_pod_subnet_id": "46a96b20-c79a-462d-98cb-43f517f4c76f",
            "kuryr_openstack_project_domain_name": "Default",
            "kuryr_openstack_project_id": "fca7a9346b8947c6a20e3b3e974243f5",
            "kuryr_openstack_service_subnet_id": "d981544f-8801-4d07-9651-80912f35348b",
            "kuryr_openstack_user_domain_name": "Default",
            "kuryr_openstack_username": "shiftstack_user",
            "kuryr_openstack_worker_nodes_subnet_id": "a5fa1e0d-15d9-4769-8175-13177ea8e924",
            "openshift_master_cluster_hostname": "172.30.0.1"                      <<---------
        }
    }

With previous OCP versions, the parameter "openshift_master_cluster_hostname" was being deleted from the inventory.
