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 Controller

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

Controller is the controller implementation for Rollout resources

func NewController

func NewController(cfg ControllerConfig) *Controller

NewController returns a new rollout controller

func (*Controller) NewTrafficRoutingReconciler

func (c *Controller) NewTrafficRoutingReconciler(roCtx rolloutContext) (TrafficRoutingReconciler, error)

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

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.

type ControllerConfig

type ControllerConfig struct {
	Namespace                       string
	KubeClientSet                   kubernetes.Interface

	DefaultIstioVersion             string
	DefaultTrafficSplitVersion      string
}

ControllerConfig describes the data required to instantiate a new rollout controller

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

}

TrafficRoutingReconciler common function across all TrafficRouting implementation
