如何使用prometheus operator部署prometheus？

Question

我正在尝试使用 Prometheus 运算符部署 Prometheus。我使用了 https://github.com/prometheus-operator/prometheus-operator 中的文档和 helm 图表。由于我需要图表供将来参考，而不是直接从存储库安装图表，我制作了一个 Chart.yaml 文件并将存储库添加为依赖项。

apiVersion: v2
description: kube-prometheus-stack collects Kubernetes manifests, Grafana dashboards, and Prometheus rules combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator.

  repository: https://grafana.github.io/helm-charts
  condition: grafana.enabled

Chart.yaml 文件

然后我执行下面的命令

hem dependency update 
helm install <chartname> .

一切正常，但是当我检查 pods 时，只创建了操作员 pod 和运行其他服务和 grafana。这是Prometheus算子的默认行为吗

我认为这可能是 Prometheus 的默认行为，所以我尝试使用 redis-cluster 运算符部署 redis-cluster 以及使用 rabitmq-cluster 运算符部署 rabbitmq-cluster，但每个都只创建运算符 pod 而不是集群 pods.

Answer 1

操作员 pod 充当控制器，侦听有关特定自定义资源的事件。如果你只部署算子，你必须单独部署你希望创建的自定义资源。

与 prometeus-operator，这将是一种“普罗米修斯”的自定义资源。如果您选择的 helm chart 也能够部署这个（或不能）应该被指出在图表 values.yaml 中并记录在他们的 github 页面上。

您还可以使用 prometheus-operator 存储库中的示例来创建 prometheus 实例。查看这些文件来执行此操作：https://github.com/prometheus-operator/prometheus-operator/tree/main/example/rbac/prometheus
