希望得到一点帮助，我的 Google-Fu 并没有让我更接近。我正在尝试为我的 fedora-coreos kubernetes 4 节点集群安装指标服务器，如下所示：

kubectl apply -f deploy/kubernetes/
clusterrole.rbac.authorization.k8s.io/system:aggregated-metrics-reader created
clusterrolebinding.rbac.authorization.k8s.io/metrics-server:system:auth-delegator created
rolebinding.rbac.authorization.k8s.io/metrics-server-auth-reader created
apiservice.apiregistration.k8s.io/v1beta1.metrics.k8s.io created
serviceaccount/metrics-server created
deployment.apps/metrics-server created
service/metrics-server created
clusterrole.rbac.authorization.k8s.io/system:metrics-server created
clusterrolebinding.rbac.authorization.k8s.io/system:metrics-server created

该服务似乎永远不会启动

我已经将 kube-prometheus-stack 作为我的掌舵图中的依赖项安装在 Mac Kubernetes 集群 v1.19.7 的本地 docker 上。我可以查看 kube-prometheus-stack 提供的默认 prometheus 目标。

我有一个 python flask 服务，它提供了我可以在 kubernetes 集群中使用kubectl port forward.

但是，我无法在 prometheus 目标 Web 界面上显示这些指标。

该KUBE-普罗米修斯堆栈文档指出Prometheus.io/scrape不支持服务的基于注解的发现。相反，读者被称为概念ServiceMonitors和PodMonitors。

因此，我已将我的服务配置如下：
