func VolumeName(volName string) string

VolumeName returns the real spec.volumes[*].name of pod TODO(liubo02): extract to namer pkg

Types ¶

type ReconcileContext ¶

type ReconcileContext struct {
	State

	LeaderEvicting bool

	Store    *pdv1.Store
	PDSynced bool

	// IsStoreReady will be set only when pd is synced and the store is ok
	// It may be outdated so the tikv is healthy only when the pod is also available
	// If it's true and the pod is ready but not available,
	// the operator will retry to avoid unexpectedly missing next reconciliation
	IsStoreReady bool
}
