Functions

func SanitizeSTS

func SanitizeSTS(sts *appsv1.StatefulSet)

SanitizeSTS removes values for APIVersion and Kind from the VolumeClaimTemplates. This prevents update failures due to these fields changing when applied. See https://github.com/kubernetes/kubernetes/issues/87583

func (*Metrics) MustRegister

func (m *Metrics) MustRegister(metrics ...prometheus.Collector)

MustRegister registers metrics with the Metrics registerer.

func (*Metrics) NewInstrumentedListerWatcher

func (m *Metrics) NewInstrumentedListerWatcher(lw cache.ListerWatcher) cache.ListerWatcher

NewInstrumentedListerWatcher returns a cache.ListerWatcher with instrumentation.

func (*Metrics) ReconcileErrorsCounter

func (m *Metrics) ReconcileErrorsCounter() prometheus.Counter

ReconcileErrorsCounter returns a counter to track reconciliation errors.

func (*Metrics) StsDeleteCreateCounter

func (m *Metrics) StsDeleteCreateCounter() prometheus.Counter

StsDeleteCreateCounter returns a counter to track statefulset's recreations.

func (*Metrics) TriggerByCounter

func (m *Metrics) TriggerByCounter(triggered_by, action string) prometheus.Counter

TriggerByCounter returns a counter to track operator actions by operation (add/delete/update) and action.
