- Prometheus需要修改yml配置，集群里需要改ConfigMap ```yml - job_name: 'k8s-service-endpoints' kubernetes_sd_configs: - role: endpoints relabel_configs: - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_scrape] action: keep regex: true - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_scheme] action: replace target_label: __scheme__ regex: (https?) - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_path] action: replace target_label: __metrics_path__ regex: (.+) - source_labels: [__address__, __meta_kubernetes_service_annotation_prometheus_io_port] action: replace target_label: __address__ regex: ([^:]+)(?::\d+)?;(\d+) replacement: $1:$2 - action: labelmap regex: __meta_kubernetes_service_label_(.+) - source_labels: [__meta_kubernetes_namespace] action: replace target_label: kubernetes_namespace - source_labels: [__meta_kubernetes_service_name] action: replace target_label: kubernetes_name ``` - Service里面需要增加两项annotations ```yaml kind: Service apiVersion: v1 metadata: name: redis namespace: candide-dev annotations: prometheus.io/scrape: "true" prometheus.io/port: "9121" spec: selector: app: redis ports: - name: redis port: 6379 targetPort: 6379 - name: prom port: 9121 targetPort: 9121 ``` - 配置完就可以集群自动发现打了prometheus的annotations对应的endpoints了
