Functions

func GetExperimentFromTemplate

func GetExperimentFromTemplate(r *v1alpha1.Rollout, stableRS, newRS *appsv1.ReplicaSet) (*v1alpha1.Experiment, error)

GetExperimentFromTemplate takes the canary experiment step and converts it to an experiment

Types

type RolloutController

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

RolloutController is the controller implementation for Rollout resources

func NewRolloutController

func NewRolloutController(
	namespace string,
	kubeclientset kubernetes.Interface,
	argoprojclientset clientset.Interface,
	dynamicclientset dynamic.Interface,
	experimentInformer informers.ExperimentInformer,

	ingressWorkQueue workqueue.RateLimitingInterface,
	metricsServer *metrics.MetricsServer,
	recorder record.EventRecorder,
	defaultIstioVersion string) *RolloutController

NewRolloutController returns a new rollout controller

func (*RolloutController) NewTrafficRoutingReconciler

func (c *RolloutController) NewTrafficRoutingReconciler(roCtx rolloutContext) TrafficRoutingReconciler

NewTrafficRoutingReconciler identifies return the TrafficRouting Plugin that the rollout wants to modify

func (*RolloutController) Run

func (c *RolloutController) 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.

type RolloutPodRestarter

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

RolloutPodRestarter describes the components needed for the controller to restart all the pods of a rollout.

func (*RolloutPodRestarter) Reconcile

func (p *RolloutPodRestarter) Reconcile(roCtx rolloutContext) error

type SortReplicaSetsByPriority

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

SortReplicaSetsByPriority sorts the ReplicaSets with the following Priority: 1. Stable RS 2. New RS 3. Older ReplicaSets

func NewSortReplicaSetsByPriority

func NewSortReplicaSetsByPriority(roCtx rolloutContext) SortReplicaSetsByPriority

func (SortReplicaSetsByPriority) Len

func (s SortReplicaSetsByPriority) Len() int

func (SortReplicaSetsByPriority) Less

func (s SortReplicaSetsByPriority) Less(i, j int) bool

func (SortReplicaSetsByPriority) Swap

func (s SortReplicaSetsByPriority) Swap(i, j int)

type TrafficRoutingReconciler

type TrafficRoutingReconciler interface {
	Reconcile(desiredWeight int32) error
	Type() string
}

TrafficRoutingReconciler common function across all TrafficRouting implementation
