type Interface

type Interface interface {
	// EnsureCreated is called when the observed runtime object is created or
	// updated. After the successful execution of EnsureCreated, systems being managed have
	// created or updated system resources. This method must be idempotent.
	EnsureCreated(ctx context.Context, obj interface{}) error
	// EnsureDeleted is called when the observed runtime object is requested to be
	// deleted, which means its DeletionTimestamp is set, but the runtime object
	// itself is not garbage collected yet. After the execution of EnsureDeleted,
	// systems being managed have deleted system resources. If deletion could not
	// be done successfully resource implementations must request to keep
	// finalizers using the available controller context control flow primitives.
	// In case EnsureDeleted returns an error, finalizers are kept automatically.
	// This method must be idempotent.
	EnsureDeleted(ctx context.Context, obj interface{}) error
	// Name returns the resource's name used for identification e.g. in logging
	// and metrics components.
	Name() string
}

Interface defines the building blocks of an operator's reconciliation logic. Note there can be multiple Resources reconciling the same object in a chain. In that case they are guaranteed to be executed in order one after another.
