Constants

const Label = "cache"

Label is a constant for the label of the cache prometheus instance.

Functions

func AdditionalScrapeConfigs

func AdditionalScrapeConfigs(isManagedSeed bool) ([]string, error)

AdditionalScrapeConfigs returns the additional scrape configs for the cache prometheus.

func CentralPrometheusRules

func CentralPrometheusRules() []*monitoringv1.PrometheusRule

CentralPrometheusRules returns the central PrometheusRule resources for the cache prometheus.

func CentralServiceMonitors

func CentralServiceMonitors() []*monitoringv1.ServiceMonitor

CentralServiceMonitors returns the central ServiceMonitor resources for the cache prometheus.

func NetworkPolicyToKubelet

func NetworkPolicyToKubelet(namespace string, nodeCIDR *string) *networkingv1.NetworkPolicy

NetworkPolicyToKubelet returns a NetworkPolicy that allows traffic from the cache Prometheus to the kubelet process running on the nodes.

func NetworkPolicyToNodeExporter

func NetworkPolicyToNodeExporter(namespace string, nodeCIDR *string) *networkingv1.NetworkPolicy

NetworkPolicyToNodeExporter returns a NetworkPolicy that allows traffic from the cache Prometheus to the node-exporter pods running in `kube-system` namespace. Note that it is only applicable/relevant in case the seed cluster is a shoot cluster itself (otherwise, there won't be a running node-exporter (typically)). The gardener-resource-manager's NetworkPolicy controller is not enabled for the kube-system namespace, hence we need to create this custom policy for this network path.

Types

type Data

type Data struct {
	IsManagedSeed bool
}

Data represents the data for the template.
