Openstack Cloud Provider

To enable the Openstack cloud provider, besides setting the name as openstack, there are specific configuration options that must be set. The Openstack configuration options are grouped into different sections.

cloud_provider:
    name: openstack
    openstackCloudProvider:
      global:
        username: xxxxxxxxxxxxxx
        password: xxxxxxxxxxxxxx
        auth-url: https://1.2.3.4/identity/v3
        tenant-id: xxxxxxxxxxxxxx
        domain-id: xxxxxxxxxxxxxx
      load_balancer:
        subnet-id: xxxxxxxxxxxxxx
      block_storage:
        ignore-volume-az: true
      route:
        router-id: xxxxxxxxxxxxxx
      metadata:
        search-order: xxxxxxxxxxxxxx

Overriding the hostname

The OpenStack cloud provider uses the instance name (as determined from OpenStack metadata) as the name of the Kubernetes Node object, you must override the Kubernetes name on the node by setting the hostname_override for each node. If you do not set the hostname_override, the Kubernetes node name will be set as the address, which will cause the Openstack cloud provider to fail.
