var ErrNoSLORules = fmt.Errorf("0 SLO Prometheus rules generated")

ErrNoSLORules will be used when there are no rules to store. The upper layer could ignore or handle the error in cases where there wasn't an output.

func (f FakeKubernetesService) EnsurePrometheusRule(ctx context.Context, pr *monitoringv1.PrometheusRule) error

func (FakeKubernetesService) EnsurePrometheusServiceLevelStatus 

func (f FakeKubernetesService) EnsurePrometheusServiceLevelStatus(ctx context.Context, slo *slothv1.PrometheusServiceLevel, err error) error

func (f FakeKubernetesService) WatchPrometheusServiceLevels(ctx context.Context, ns string, opts metav1.ListOptions) (watch.Interface, error)

type IOWriterPrometheusOperatorYAMLRepo 

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

IOWriterPrometheusOperatorYAMLRepo knows to store all the SLO rules (recordings and alerts) grouped in an IOWriter in Kubernetes prometheus operator YAML format.

func NewIOWriterPrometheusOperatorYAMLRepo 

func NewIOWriterPrometheusOperatorYAMLRepo(writer io.Writer, logger log.Logger) IOWriterPrometheusOperatorYAMLRepo

func (IOWriterPrometheusOperatorYAMLRepo) StoreSLOs 

func (i IOWriterPrometheusOperatorYAMLRepo) StoreSLOs(ctx context.Context, kmeta K8sMeta, slos []StorageSLO) error

type K8sMeta 

type K8sMeta struct {
	Kind        string `validate:"required"`
	APIVersion  string `validate:"required"`
	Name        string `validate:"required"`
	UID         string
	Namespace   string
	Annotations map[string]string
	Labels      map[string]string
}

K8sMeta is the Kubernetes metadata simplified.

type KubernetesService 

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

func NewKubernetesService 

func NewKubernetesService(slothCli slothclientset.Interface, monitoringCli monitoringclientset.Interface, logger log.Logger) KubernetesService

NewKubernetesService returns a new Kubernetes Service.

func (KubernetesService) EnsurePrometheusRule 

func (k KubernetesService) EnsurePrometheusRule(ctx context.Context, pr *monitoringv1.PrometheusRule) error

func (KubernetesService) EnsurePrometheusServiceLevelStatus 

func (k KubernetesService) EnsurePrometheusServiceLevelStatus(ctx context.Context, slo *slothv1.PrometheusServiceLevel, err error) error

EnsurePrometheusServiceLevelStatus updates the status of a PrometheusServiceLeve, be aware that updating an status will trigger a watch update event on a controller. In case of no error we will update "last correct Prometheus operation rules generated" TS so we can be in a infinite loop of handling, the handler should break this loop somehow (e.g: if ok and last generated < 5m, ignore).

func (KubernetesService) ListPrometheusServiceLevels 

func (k KubernetesService) ListPrometheusServiceLevels(ctx context.Context, ns string, opts metav1.ListOptions) (*slothv1.PrometheusServiceLevelList, error)

func (KubernetesService) WatchPrometheusServiceLevels 

func (k KubernetesService) WatchPrometheusServiceLevels(ctx context.Context, ns string, opts metav1.ListOptions) (watch.Interface, error)

type PrometheusOperatorCRDRepo 

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

PrometheusOperatorCRDRepo knows to store all the SLO rules (recordings and alerts) grouped as a Kubernetes prometheus operator CR using Kubernetes API server.

func NewPrometheusOperatorCRDRepo 

func NewPrometheusOperatorCRDRepo(ensurer PrometheusRulesEnsurer, logger log.Logger) PrometheusOperatorCRDRepo

func (PrometheusOperatorCRDRepo) StoreSLOs 

func (p PrometheusOperatorCRDRepo) StoreSLOs(ctx context.Context, kmeta K8sMeta, slos []StorageSLO) error

type PrometheusRulesEnsurer

}

type SLOGroup 

type SLOGroup struct {
	K8sMeta K8sMeta
	prometheus.SLOGroup

Validate validates the SLO.

type StorageSLO 

type StorageSLO struct {
	SLO   prometheus.SLO
	Rules prometheus.SLORules
