Types

type CallbackDispatcher

type CallbackDispatcher struct {
	// contains filtered or unexported fields
}

CallbackDispatcher manages and executes resource callbacks

func NewCallbackDispatcher

func NewCallbackDispatcher(log logr.Logger, client, uncachedClient client.Client, scheme *runtime.Scheme, namespace string) *CallbackDispatcher

NewCallbackDispatcher creates new callback dispatcher

func (*CallbackDispatcher) AddCallback

func (cd *CallbackDispatcher) AddCallback(obj runtime.Object, cb ReconcileCallback)

AddCallback registers a callback for given object type

func (*CallbackDispatcher) InvokeCallbacks

func (cd *CallbackDispatcher) InvokeCallbacks(l logr.Logger, cr interface{}, s ReconcileState, desiredObj, currentObj runtime.Object) error

InvokeCallbacks executes callbacks for desired/current object type

type ReconcileCallback

type ReconcileCallback func(args *ReconcileCallbackArgs) error

ReconcileCallback is the callback function

type ReconcileCallbackArgs

type ReconcileCallbackArgs struct {
	Logger    logr.Logger
	Client    client.Client
	Scheme    *runtime.Scheme
	Namespace string
	Resource  interface{}

	State         ReconcileState
	DesiredObject runtime.Object
	CurrentObject runtime.Object
}

ReconcileCallbackArgs contains the data of a ReconcileCallback

type ReconcileState

type ReconcileState string

ReconcileState is the current state of the reconcile for a particuar resource

const (
	// ReconcileStatePreCreate is the state before a resource is created
	ReconcileStatePreCreate ReconcileState = "PRE_CREATE"
	// ReconcileStatePostCreate is the state sfter a resource is created
	ReconcileStatePostCreate ReconcileState = "POST_CREATE"

	// ReconcileStatePostRead is the state sfter a resource is read
	ReconcileStatePostRead ReconcileState = "POST_READ"

	// ReconcileStatePreUpdate is the state before a resource is updated
	ReconcileStatePreUpdate ReconcileState = "PRE_UPDATE"
	// ReconcileStatePostUpdate is the state after a resource is updated
	ReconcileStatePostUpdate ReconcileState = "POST_UPDATE"

	// ReconcileStatePreDelete is the state before a resource is explicitly deleted (probably during upgrade)
	// don't count on this always being called for your resource
	// ideally we just let garbage collection do it's thing
	ReconcileStatePreDelete ReconcileState = "PRE_DELETE"
	// ReconcileStatePostDelete is the state after a resource is explicitly deleted (probably during upgrade)
	// don't count on this always being called for your resource
	// ideally we just let garbage collection do it's thing
	ReconcileStatePostDelete ReconcileState = "POST_DELETE"

	// ReconcileStateOperatorDelete is called during CR finalizer
	ReconcileStateOperatorDelete ReconcileState = "OPERATOR_DELETE"
