+# Moon
+
+Moon 是一款集成prometheus系列的监控管理工具，专为简化Prometheus监控系统的运维工作而设计。该工具提供了一站式的解决方案，能够集中管理和配置多个Prometheus实例及其相关的服务发现、规则集和警报通知。
+
+本 chart 使用 [Helm](https://helm.sh) 包管理器实现在[Kubernetes](https://kubernetes.io) (k8s)集群上部署moon
+
+## 安装Chart
+
+注意: 暂时只支持helm3
+
+- 通过源码安装(本示例默认源码安装)
+
+  ```
+  kubectl create ns moon
+  helm install [RELEASE_NAME] moon/ -n moon 
+  ```
+
+- 修改默认参数后, 打包上传到repos后, 例如https://artifacthub.io/, 再行安装
+
+  ```
+  helm repo add moon https://xxxx.xxx.xx/moon
+  helm repo update
+  helm install [RELEASE_NAME] ./moon -n moon
+  ```
+
+## 卸载Chart
+
+通过以下命令卸载:
+
+```console
+helm delete moon -n moon
+```
+
+## 更新Chart
+
+```
+helm upgrade [RELEASE_NAME] [CHART] -n moon --install
+```
+
+## 配置
+
+- 详情请参考: [values.yaml](./values.yaml)
+
+- 自定义参数:
+
+  ```
+  helm install moon moon/ --set=service.port=31008,resources.limits.cpu=300m
+  ```

+description: A Helm chart for Kubernetes
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 0.1.0
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.
