Functions

func CopyFromExisting

func CopyFromExisting(expected, existing *appsv1.StatefulSet)

CopyFromExisting copies fields that should not be changed from existing to expected.

func GetPVCNames

func GetPVCNames(statefulSet *appsv1.StatefulSet) []string

GetPVCNames generates the expected PVC names of a statefulset, given its replica count {volumeClaimTemplate name}-{sts name}-{replica ordinal}

func New

func New(log vzlog.VerrazzanoLogger, vmo *vmcontrollerv1.VerrazzanoMonitoringInstance, storageClass *storagev1.StorageClass, initialMasterNodes string) ([]*appsv1.StatefulSet, error)

New creates StatefulSet objects for a VMO resource

Types

type StatefulSetPlan

type StatefulSetPlan struct {
	Create          []*appsv1.StatefulSet
	Update          []*appsv1.StatefulSet
	Delete          []*appsv1.StatefulSet
	Conflict        error
	ExistingCluster bool
	BounceNodes     bool
}

StatefulSetPlan describes how to update the cluster statefulsets

func CreatePlan

func CreatePlan(log vzlog.VerrazzanoLogger, existingList, expectedList []*appsv1.StatefulSet) *StatefulSetPlan

CreatePlan creates a plan for sts that need to be created, updated, or deleted. if the cluster is not safe to scale down, updates/deletes will be rejected.
