summary
Shows how Prometheus Operator uses eight CRDs (Prometheus, Alertmanager, ThanosRuler, ServiceMonitor, PodMonitor, Probe, PrometheusRule, AlertmanagerConfig) to auto-generate Prometheus configs, reload via a sidecar, and operate Alertmanager and Thanos; includes concrete examples for TLS config, remote_write with queue and OAuth2 auth, and Probe blackbox checks. Describes kube-prometheus ready-to-run manifests, Grafana mixins workflow, and claims daily maintenance across thousands of OpenShift clusters while noting scaling and configurability limits.
