Constants

const (
	// ProviderName is the name of the openstack provider
	ProviderName = "openstack"

	// TypeHostName is the name type of openstack instance
	TypeHostName = "hostname"
)
View Source 
const (
	ServiceAnnotationLoadBalancerFloatingNetworkID = "loadbalancer.openstack.org/floating-network-id"
	ServiceAnnotationLoadBalancerSubnetID          = "loadbalancer.openstack.org/subnet-id"

	// ServiceAnnotationLoadBalancerInternal is the annotation used on the service
	// to indicate that we want an internal loadbalancer service.
	// If the value of ServiceAnnotationLoadBalancerInternal is false, it indicates that we want an external loadbalancer service. Default to false.
	ServiceAnnotationLoadBalancerInternal = "service.beta.kubernetes.io/openstack-internal-load-balancer"
)

Note: when creating a new Loadbalancer (VM), it can take some time before it is ready for use, this timeout is used for waiting until the Loadbalancer provisioning status goes to ACTIVE state.
