	// contains filtered or unexported fields
}

func NewResource

func NewResource(config ResourceConfig) (*Resource, error)

func (r *Resource) EnsureCreated(ctx context.Context, obj interface{}) error

EnsureCreated creates DrainerConfigs for ASG instances in terminating/wait state then lets node-operator to do its job.

func (*Resource) EnsureDeleted

func (r *Resource) EnsureDeleted(ctx context.Context, obj interface{}) error

EnsureDeleted is a no-op, because the lifecycle resource only has to act on create and update events in order to drain guest cluster nodes.

func (*Resource) Name

func (r *Resource) Name() string

type ResourceConfig

type ResourceConfig struct {
	G8sClient versioned.Interface
	Logger    micrologger.Logger
}

type StackState

type StackState struct {
	Instances     []*autoscaling.Instance
	WorkerASGName string
}
