Functions

func CreateTwoWayMergePatch

func CreateTwoWayMergePatch(orig, new, dataStruct interface{}) ([]byte, bool, error)

CreateTwoWayMergePatch is a helper to construct a two-way merge patch from objects (instead of bytes)

func GetActiveReplicaSet

func GetActiveReplicaSet(rollout *v1alpha1.Rollout, allRS []*appsv1.ReplicaSet) *appsv1.ReplicaSet

GetActiveReplicaSet finds the replicaset that is serving traffic from the active service or returns nil

Types

type Controller

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

Controller is the controller implementation for Rollout resources

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	rolloutsclientset clientset.Interface,
	replicaSetInformer appsinformers.ReplicaSetInformer,
	serviceInformer coreinformers.ServiceInformer,
	rolloutsInformer informers.RolloutInformer,
	resyncPeriod time.Duration) *Controller

NewController returns a new rollout controller

func (*Controller) Run

func (c *Controller) Run(threadiness int, stopCh <-chan struct{}) error

Run will set up the event handlers for types we are interested in, as well as syncing informer caches and starting workers. It will block until stopCh is closed, at which point it will shutdown the workqueue and wait for workers to finish processing their current work items.
