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

func GetScaleDownRevisionLimit

func GetScaleDownRevisionLimit(ro *v1alpha1.Rollout) int32

func NewInformerBasedWorkloadRefResolver

func NewInformerBasedWorkloadRefResolver(
	namespace string,
	dynamicClient dynamic.Interface,
	discoClient discovery.DiscoveryInterface,
	agrgoProjClientset clientset.Interface,
	rolloutsInformer cache.SharedIndexInformer,
) *informerBasedTemplateResolver

NewInformerBasedWorkloadRefResolver create new instance of workload ref resolver.

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) ([]trafficrouting.TrafficRoutingReconciler, error)

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

func (*Controller) Run

func (c *Controller) Run(ctx context.Context, threadiness int) 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
	ArgoProjClientset               clientset.Interface
	DynamicClientSet                dynamic.Interface
	RefResolver                     TemplateRefResolver
	SmiClientSet                    smiclientset.Interface
	ExperimentInformer              informers.ExperimentInformer
	AnalysisRunInformer             informers.AnalysisRunInformer
	AnalysisTemplateInformer        informers.AnalysisTemplateInformer
	ClusterAnalysisTemplateInformer informers.ClusterAnalysisTemplateInformer
	ReplicaSetInformer              appsinformers.ReplicaSetInformer
	ServicesInformer                coreinformers.ServiceInformer
	IngressWrapper                  IngressWrapper

	IstioVirtualServiceInformer     cache.SharedIndexInformer
	IstioDestinationRuleInformer    cache.SharedIndexInformer
	ResyncPeriod                    time.Duration
	RolloutWorkQueue                workqueue.RateLimitingInterface
	ServiceWorkQueue                workqueue.RateLimitingInterface

	MetricsServer                   *metrics.MetricsServer
	Recorder                        record.EventRecorder
}

ControllerConfig describes the data required to instantiate a new rollout controller

type IngressWrapper

type IngressWrapper interface {
	GetCached(namespace, name string) (*ingressutil.Ingress, error)
	Get(ctx context.Context, namespace, name string, opts metav1.GetOptions) (*ingressutil.Ingress, error)
	Patch(ctx context.Context, namespace, name string, pt types.PatchType, data []byte, opts metav1.PatchOptions, subresources ...string) (*ingressutil.Ingress, error)
	Create(ctx context.Context, namespace string, ingress *ingressutil.Ingress, opts metav1.CreateOptions) (*ingressutil.Ingress, error)
}

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

Reconcile gets all pods of a Rollout and confirms that have creationTimestamps newer than spec.restartAt. If not, iterates pods and deletes pods which do not have a deletion timestamp, and were created before spec.restartedAt. If the rollout is a canary rollout, it can restart multiple pods, up to maxUnavailable or 1, whichever is greater.

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 TemplateRefResolver

type TemplateRefResolver interface {
	Resolve(r *v1alpha1.Rollout) error
}
