前置条件

安装配置

说明：示例 kube-state-metrics 版本为 2.3.0，Kubernetes 集群 1.22.6 。

部署实施

(Kubernetes 集群)

指标采集 (必选)

1、 修改镜像

解压 kube-state-metrics-2.3.0.zip ，部署使用 kube-state-metrics-2.3.0\examples\standard\ 目录下的文件，打开 deployment.yaml 修改 k8s.gcr.io/kube-state-metrics/kube-state-metrics:v2.3.0 为 bitnami/kube-state-metrics:2.3.0。

注意： 如果原始镜像可访问，不必修改。

2、 开通 Prom 采集器

打开 deployment.yaml 增加 annotations

spec:
  template:
    metadata:
      annotations:
        datakit/prom.instances: |
          [[inputs.prom]]
            urls = ["http://$IP:8080/metrics"]
            source = "prom_state_metrics"
            metric_types = ["counter", "gauge"]
            interval = "60s"
            tags_ignore = ["access_mode","branch","claim_namespace","cluster_ip","condition","configmap","container","container_id","container_runtime_version","created_by_kind","created_by_name","effect","endpoint","external_name","goversion","host_network","image","image_id","image_spec","ingress","ingressclass","internal_ip","job_name","kernel_version","key","kubelet_version","kubeproxy_version","lease","mutatingwebhookconfiguration","name","networkpolicy","node","node_name","os_image","owner_is_controller","owner_kind","owner_name","path","persistentvolume","persistentvolumeclaim","pod_cidr","pod_ip","poddisruptionbudget","port_name","port_number","port_protocol","priority_class","reason","resource","result","revision","role","secret","service","service_name","service_port","shard_ordinal","status","storageclass","system_uuid","type","uid","unit","version","volume","volumename"]
            metric_name_filter = ["kube_pod_status_phase","kube_pod_container_status_restarts_total","kube_daemonset_status_desired_number_scheduled","kube_daemonset_status_number_ready","kube_deployment_spec_replicas","kube_deployment_status_replicas_available","kube_deployment_status_replicas_unavailable","kube_replicaset_status_ready_replicas","kube_replicaset_spec_replicas","kube_pod_container_status_running","kube_pod_container_status_waiting","kube_pod_container_status_terminated","kube_pod_container_status_ready"]
            #measurement_prefix = ""
            measurement_name = "prom_state_metrics"
            #[[inputs.prom.measurements]]
            # prefix = "cpu_"
            # name = "cpu"         
            [inputs.prom.tags]
            namespace = "$NAMESPACE"
            pod_name = "$PODNAME"

3、 部署

kubectl apply -f service-account.yaml
kubectl apply -f cluster-role.yaml
kubectl apply -f cluster-role-binding.yaml
kubectl apply -f deployment.yaml

4、 查看监控数据

kubectl get pods -n kube-system -owide
