prometheus-operator-app release v24.0.0

Changed

• Upgraded chart dependency to kube-prometheus-stack-91.2.3 (from 88.6.3, via 90.0.0)
  • prometheus-operator (and prometheus-config-reloader) from v0.93.1 to v0.94.0
  • grafana subchart from 12.11.2 to 13.2.4, which switches the Grafana image from 13.2.0 to 13.2.1-distroless, enables readOnlyRootFilesystem on the Grafana container (with a new /tmp emptyDir) and sets plugins.preinstall_auto_update = false
  • k8s-sidecar (Grafana dashboard/datasource sidecar) from 2.10.1 to 2.11.2
  • kube-state-metrics subchart from 8.4.1 to 8.4.2 (KSM image unchanged at v2.20.0)
  • prometheus-node-exporter subchart from 4.56.3 to 4.57.0 (we keep nodeExporter.enabled: false, no impact)
  • Alertmanager, Prometheus, Thanos and kube-webhook-certgen images are unchanged.
• Breaking (chart 90.0.0): the control-plane ServiceMonitors (kubelet, kube-apiserver, kube-controller-manager, kube-scheduler, kube-etcd, kube-proxy, coredns) no longer use bearerTokenFile/tlsConfig.caFile. They now authenticate through a kubernetes.io/service-account-token Secret (<release>-prometheus-token, newly created by the chart) and read the CA from the kube-root-ca.crt ConfigMap. This makes the ServiceMonitors work with arbitraryFSAccessThroughSMs.deny and with Grafana Alloy’s prometheus.operator.servicemonitors component (>= v1.19.0), which silently dropped every control-plane target before.
• Breaking (chart 91.0.0 / operator v0.94.0): the Prometheus Operator ClusterRole no longer grants wildcard (*) verbs. Verbs are now explicit per resource group, and the operator only gets get/list/watch on the monitoring.coreos.com CRs plus writes on their /status and /finalizers subresources.
• prometheusOperator.admissionWebhooks.matchConditions changed type from a map ({}) to a list ([]). We do not set it, so no impact.
• Fixed the chart appVersion, which was still v0.92.0, to match the bundled Prometheus Operator (v0.94.0).
• Added global.controlPlaneScrapeAuth to configure the Secret the control-plane ServiceMonitors authenticate with.
• Dropped the scrape credential for coreDns, kubeEtcd and kubeProxy.
• Removed insecureSkipVerify from the kubeControllerManager and kubeScheduler ServiceMonitors.

Note: release the matching prometheus-operator-crd app (CRDs chart 32.0.0, Prometheus Operator v0.94.0) before this one. The CRDs shipped by this chart live in charts/crds/crds/ and are therefore only applied by Helm on install, never on upgrade.
