Types

type Handler

type Handler interface {
	CanHandle(resourceName string) bool
	HandleCreate(resourceName string, requestCount int, pod *v1.Pod) (ctrl.Result, error)
	HandleDelete(resourceName string, pod *v1.Pod) (ctrl.Result, error)
}

Handler interface allows different types of resource implementation to be clubbed under a single handler. For instance, warm resource handler would handle all the types of resources that support warm pools. An example of warm pool resource is IPv4. Another example of handler is on demand handler, resources that can be only processed on demand would fit into this category. For instance, Branch ENIs are tied to the Security Group required by the pod which we would know only after receiving the pod request.

func NewOnDemandHandler

func NewOnDemandHandler(log logr.Logger, ondDemandProviders map[string]provider.ResourceProvider) Handler

NewOnDemandHandler returns a new on demand handler with all the workers that can handle particular resource types

func NewWarmResourceHandler

func NewWarmResourceHandler(log logr.Logger, k8sWrapper k8s.K8sWrapper,
	resourceProviders map[string]provider.ResourceProvider) Handler
